The normal result of the trade wind blowing from South America to Indonesia and Australia warm water produces rainy weather in Indonesia and Australia. Option D

We know that the trade winds are the winds that tend to originate at the north east or the south eastern parts of the hemisphere and tend to be blowing across the seas towards the equator. Thus we can see that the focus of the trade winds is the equator and they emanate from north or south.

One of the effects of the trade winds is that they make the wind warmer and that would make to the emergence of a warmer weather and this would spread to the other parts of the word as we can see from map studies.

The effects of the trade winds  blowing from South America would tend  to be much more felt around the areas of  Indonesia and Australia and this is very important to weather changes around those areas.

It would take 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

To calculate the time required to crumple the barrier and safely slow down the person, we can use the concept of impulse.

The impulse, denoted by J, is defined as the product of force and time, and it represents the change in momentum of an object. In this case, the impulse required to safely slow down the person can be calculated using the maximum force and the person's initial momentum.

The momentum of a person is given by the product of their mass and velocity:

Momentum = mass × velocity

Given that the person's mass is 68 kg and their velocity is 27 m/s, the initial momentum is:

Initial momentum = 68 kg × 27 m/s

To safely slow down the person, the impulse provided by the barrier should be equal to the change in momentum.

Therefore, we have:

Impulse provided by barrier = Final momentum - Initial momentum

Since the person is brought to rest, the final momentum is zero. Thus, we have:

Impulse provided by barrier = -Initial momentum

Now we can express the impulse in terms of force and time:

Impulse provided by barrier = Force × Time

Plugging in the known values, we can solve for time:

-Initial momentum = Force × Time

68 kg × 27 m/s = 1180 N × Time

Simplifying the equation, we find:

Time = (68 kg × 27 m/s) / 1180 N

Evaluating the expression:

Time = 1836 kg·m/s / 1180 N

Finally, converting kg·m/s to seconds, we get:

Time ≈ 1.5559 seconds

Therefore, it would take approximately 1.556 seconds for the barrier to crumple and safely slow down the person with a force of 1180 N.

The density of the object is 5911.94 kg/m³

An object's buoyancy is the upward force produced by a fluid in opposition to the weight of a partly or totally submerged object.

The buoyancy = weight of the object - weight in water

= 15 N - 13N

= 2 N

The buoyancy force can also be determined by using the expressed:

\(\mathbf{F_B = Volume (V) \times density ( \rho) \times g}\)

\(\mathbf{2 = Volume (V) \times788 \ kg/m^3 \times9.8 }\)

\(\mathbf{ Volume (V) = \dfrac{2}{ 788 \ kg/m^3 \times9.8 }}\)

volume (v) = 2.589 × 10⁻⁴m³

Recall that:

The mass of an object can be estimated by using the formula:

Weight = mass × gravity

mass = Weight / gravity

mass = 15/9.8

mass = 1.5306 kg

The density of the object can now be calculated using the relation

Density = mass/volume

Density = 1.5306 kg / 2.589 × 10⁻⁴m³

True. Under electrostatic conditions, an electric field intersects the surface of a conductor at a right angle.

This is because a conductor is a material that allows electric charges to flow freely on its surface, and the electric field inside a conductor is zero. When an electric field is present outside a conductor, it will produce an electric potential difference across the surface of the conductor, which will cause electric charges to redistribute themselves on the surface of the conductor until the electric field inside the conductor is zero.

This phenomenon is known as the electric field being screened by the conductor. The electric charges that are redistributed on the surface of the conductor will produce an electric field that opposes the original electric field, and this new electric field will intersect the surface of the conductor at a right angle. This means that the direction of the electric field at the surface of a conductor is always perpendicular to the surface of the conductor.

The mass of the copper block dropped into 539g of water initially at 70oC, that resulted in an equilibrium temperature of 64oC, is 257g.

In this instance, 539g of water that was initially at 70oC was put into a copper block that had an initial temperature of 13oC, and they eventually achieved an equilibrium temperature of 64oC. We may construct the following equation using the formula Q = mcT, where Q is the quantity of heat transferred, m is the mass of the material, c is the specific heat capacity, and T is the change in temperature: mcT copper = mcT water  where "copper" refers to the copper block and "water" refers to the water. m copper (0.385 J/g°C)(64°C - 13°C) = m T copper (539 g)(4.18 J/g°C)(70°C - 64°C) m copper is calculated as follows: (539 g)(4.18 J/g°C)(70°C - 64°C) / (0.385 J/g°C)(64°C - 13°C)

Answer:

Explanation:

Given that Bert is standing on a ladder picking apples in his grandfather’s orchard. As he pulls each apple off the tree, he tosses it into a basket that sits on the ground 5.0 m below at a horizontal displacement of 2.0 m from Bert.

Let us use pythagorean theorem

H = sqrt ( 5^2 + 2^2 )

H = sqrt ( 25 + 4 )

H = sqrt ( 29 )

H = 5.385 m

Using the third equation of motion

V^2 = U^2 + 2gH

But U = 0

V^2 = 2 × 9.8 × 5.385

V^2 = 105.549

V = sqrt ( 105.549 )

V = 10.27 m/s

Therefore, Bert will throw the apples (horizontally) in order to land in the basket as fast as 10.3 m/s approximately.

When looking through a linear polarizer at a light source producing randomly polarized light the light intensity will fluctuate between 100% and 0% (no light) as the polarizer is rotated 360°.

Therefore the answer is B.

Linear polarizers are used to filter light that is polarized in a particular direction. If the light source is producing randomly polarized light, then the light waves are oriented in many different directions. When the light passes through a linear polarizer, only the light waves that are aligned with the polarizer's axis are transmitted, while the others are absorbed.

As the polarizer is rotated, the transmitted light intensity will decrease until the polarizer's axis is perpendicular to the orientation of the light waves, at which point no light is transmitted. As the polarizer is rotated further, the transmitted light intensity will increase again until it reaches maximum when the polarizer's axis is parallel to the orientation of the light waves. This results in a sinusoidal pattern of light intensity, with a maximum at 100% and a minimum at 0%, as the polarizer is rotated 360°.

Bubba generates a momentum of 216 kg·m/s, while Bertha generates a momentum of 215 kg·m/s. Therefore, Bubba would win the argument as he generates more momentum.

Given:

Bubba's mass (m1) = 27 kg

Bubba's velocity (v1) = 8 m/s

Bertha's mass (m2) = 43 kg

Bertha's velocity (v2) = 5 m/s

Bubba's momentum can be calculated as:

Momentum1 = m1 * v1

        = 27 kg * 8 m/s

        = 216 kg·m/s

Bertha's momentum can be calculated as:

Momentum2 = m2 * v2

        = 43 kg * 5 m/s

        = 215 kg·m/s

Comparing the two momenta, we can see that Bubba generates a momentum of 216 kg·m/s, while Bertha generates a momentum of 215 kg·m/s. Since Bubba's momentum is higher, Bubba would win the argument and can claim to generate more momentum.

Based on the calculations, Bubba generates more momentum than Bertha. Momentum depends on both mass and velocity, and in this case, Bubba's lower mass is compensated by his higher velocity, resulting in a greater momentum. Therefore, Bubba would win the argument and can assert that he generates more momentum.

In a storage tank with a 110-foot diameter, it would take roughly 46 hours of flow rate to raise the water level from 6.6 feet to 18.0 feet.

We need to calculate the amount of water needed to fill the tank from 6.6 feet to 18.0 feet using the formula in order to determine how long it would take to increase the water level up in the tank.

V = (π/4) x D^2 x H,

where V denotes volume, D denotes tank breadth, and H denotes the level of water that ought to have been added.

The measurement of the volume is 330,814.93 cubic feet. Using the stream rate of 2.0 cubic feet per second, we can then calculate how long it will take to fill the tank, which comes out to be 165,407.46 seconds or around 46 hours.

Accordingly, if a 110-foot width capacity tank were to be filled at a rate of 2.0 cubic feet per second, it would take around 46 hours to raise the water level from 6.6 feet to 18.0 feet.

The rate at which water is leaking out of the cone is approximately 16.76 cubic feet per minute (ft^3/min).

To determine the rate at which water is leaking out of the cone, we need to use the formula for the volume of a cone:

V = (1/3)πr^2h

where V is the volume of the cone, r is the radius of the base, and h is the height of the cone.

We also need to use the formula for related rates:

dV/dt = (∂V/∂h)(dh/dt)

where dV/dt is the rate at which the volume of the cone is changing, (∂V/∂h) is the partial derivative of the volume with respect to the height, and dh/dt is the rate at which the height of the water level is changing.

First, we need to find the radius of the cone. We can do this by using the fact that the depth of the water is 8 ft:

h = 8 ft

The cone is similar to the larger cone, so the ratio of the corresponding dimensions is the same:

r/h = 2/3

r = (2/3)h = (2/3)(8 ft) = 16/3 ft

Now we can find the volume of the cone at any time:

V = (1/3)πr^2h

V = (1/3)π[(16/3 ft)^2](h)

Next, we need to find the rate at which the height of the water level is changing:

dh/dt = -3 in/min

We need to convert this to feet per minute, since the other measurements are in feet:

dh/dt = -0.25 ft/min

Now we can find the rate at which water is leaking out of the cone:

dV/dt = (∂V/∂h)(dh/dt)

dV/dt = (2/3)πr^2(dh/dt)

dV/dt = (2/3)π[(16/3 ft)^2](-0.25 ft/min)

dV/dt ≈ -16.76 ft^3/min

The centripetal acceleration experienced by an object moving in a circle is given by the formula:

a = v²/r

where a is the centripetal acceleration, v is the speed of the object, and r is the radius of the circle.

In this problem, we are given that the object has a mass of 20 g, which we need to convert to kilograms:

m = 20 g = 0.02 kg

We are also given that the object is moving in a horizontal circle of radius 250 cm at a speed of 50 cm/s. We need to convert these measurements to SI units (meters and seconds) to use the formula for centripetal acceleration:

r = 250 cm = 2.5 m

v = 50 cm/s = 0.5 m/s

Now we can calculate the centripetal acceleration:

a = v²/r = (0.5 m/s)² / 2.5 m = 0.1 m/s²

Therefore, the centripetal acceleration experienced by the object is 0.1 m/s².

A passenger rushes down onto a subway platform and finds her train already departing. she stops and watches the cars go by. each car is 8.60 m long. the first moves past her in 2.10 s and the second in 1.83 s. The constant acceleration of the train is 236.16 m/s².

To calculate the constant acceleration of the train, we can use the following equation:

acceleration = 2 * (change in distance) / (change in time)²

Given:

Length of each car = 8.60 m

Time taken for the first car to pass = 2.10 s

Time taken for the second car to pass = 1.83 s

Step 1: Calculate the change in distance between the two cars:

change in distance = length of each car = 8.60 m

Step 2: Calculate the change in time between the two cars:

change in time = time taken for the second car to pass - time taken for the first car to pass

change in time = 1.83 s - 2.10 s = -0.27 s (The negative sign indicates that the second car passed before the first car)

Step 3: Calculate the acceleration:

acceleration = 2 * (change in distance) / (change in time)²

acceleration = 2 * 8.60 m / (-0.27 s)²

acceleration = 2 * 8.60 m / (0.27 s)²

acceleration = 2 * 8.60 m / 0.0729 s²

acceleration = 17.2 m / 0.0729 s²

acceleration = 236.16 m/s²

Therefore, the constant acceleration of the train is approximately 236.16 m/s².

The reason a 20-kg rock falls no faster than a 10-kg rock in free fall is that the force of gravity on both is the same. This is because the force of gravity is proportional to the mass of an object, so a 20-kg rock experiences twice as much force as a 10-kg rock. However, the acceleration due to gravity is also proportional to the force but inversely proportional to the mass. Therefore, the acceleration experienced by both rocks is the same, causing them to fall at the same speed.

Air resistance, on the other hand, can have a significant impact on the speed of an object in free fall. As objects fall through the air, they experience a drag force that opposes their motion. This can cause the object to reach a terminal velocity, where the force of air resistance is equal to the force of gravity, resulting in a constant speed. In cases where air resistance is not negligible, the speed at which an object falls will be impacted by the resistance it experiences.

In summary, the force of gravity is what determines the speed at which objects fall in free fall, while air resistance can impact this speed in situations where it is not negligible.

Answer:

the twenty-fourth, and last, letter of the Greek alphabet (Ω, ω), transliterated as ‘o’ or ‘ō.’.

Explanation:

The statement "the current capacity of a battery increases with an increase in current demand" is False. This is because, as the current demand of a battery increases, the battery's ability to hold its charge decreases and its capacity decreases as well, not increases.

When a battery is used, it releases energy to power whatever device is being used. When the content loaded on the device is low, the demand for current is low, and the battery can sustain the demand for a longer time.

However, when it is high, the battery's demand for current is higher, and the battery can supply energy for a shorter time, meaning that the battery's capacity has decreased due to an increase in current demand.

The battery's ability to hold its charge and supply energy is influenced by several factors, such as temperature, age, charging cycles, and discharge rates. Therefore, a battery's capacity is reduced as the demand for current increases
