A boat has a porthole window, of
area 0.00849 m^2, 6.25 m below
the surface. The density of sea
water is 1027 kg/m^3. The air
inside the boat is at 1 atm. What
is the NET force on the window?
(Unit = N)
(1 atm = 101300 Pa)
Answers
Answer:
F = 534.6[N]
Explanation:
We must find the pressure exerted by the water at the depth of the boat, by means of the following equation.
\(P=Ro*g*h\)
where:
Ro = density of sea water = 1027 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = wáter Depth = 6.25 [m]
Now replacing:
\(P=1027*9.81*6.25\\P=62967.93[Pa]\)
The net force is:
\(F = P*A\\F = 62967.93*0.00849\\F = 534.6[N]\)

The scientist whose experiments showed that tin, upon heating, combined with a gas from the air was: A)Priestley. B) Stahl. C) Lavoisier. D) Becher.
Answers
The correct answer is C) Antoine Lavoisier.
Antoine Lavoisier was a French chemist who made significant contributions to the field of chemistry during the 18th century. He is considered one of the fathers of modern chemistry and is best known for his law of conservation of mass and his work on combustion and respiration.
In one of his experiments, Lavoisier heated tin in a closed container with air and observed that the tin gained weight. This led him to conclude that the tin was combining with a gas from the air, which he later named "oxygen." This discovery helped to lay the foundation for the modern understanding of chemical reactions and the role of oxygen in combustion and respiration.

Sam jumped from a plane. His acceleration was -9.8 m/s². He hit the ground in 30
seconds. What was his velocity just before he hit the ground?
Answers
The velocity of Sam just before hitting the ground is 294 m/s.
The above situation represents a case of motion in one dimension.
This type of motion is governed by the following three equations of motion,
v = u + at
v² - u² = 2as
S = ut + 1/2 at²
As in the given case, the acceleration and time have been given and the final velocity is to be calculated, therefore the 1st equation can be used,
v = u+ at
As Sam jumped from the plane, his initial velocity is zero.
So,
v = 0 + 9.8(30)
v = 294 m/s.
Thus, Sam's velocity just before hitting the ground is 294 m/s.

Net Force (N) = 5. 0
Mass (kg) = 2. 5
What is acceleration?
Answers
The acceleration of the object is 2.0 m/s². This means that for every second the object is in motion, its velocity will increase by 2.0 meters per second.
The given information is the net force (N) = 5.0 and the mass (kg) = 2.5. We need to determine the acceleration.
Acceleration is the rate at which an object's velocity changes over time.
It is directly proportional to the net force applied to the object and inversely proportional to its mass.
The formula to calculate acceleration is:
Acceleration = Net Force / Mass
Now, let's substitute the given values into the formula:
Acceleration = 5.0 N / 2.5 kg

the weight of the atmosphere above 1 m2 of earth's surface is about 100,000 n. density, of course, becomes less with altitude. but suppose the density of air were a constant 1.2 kg/m3.
Answers
The thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is equal to 8,680.56 meters assuming the density of air remained constant at 1.2 kg/m³.
If the density of air were a constant 1.2 kg/m³ throughout the atmosphere, we can calculate the thickness of the air column that would have a weight of about 100,000 N on an area of 1 m².
The weight of the air column can be calculated using the formula:
Weight = density × volume × gravitational acceleration
We can rearrange the formula to solve for the volume:
\(\text{{Volume}} = \frac{{\text{{Weight}}}}{{\text{{density}} \times \text{{gravitational acceleration}}}}\)
Substituting the given values:
Weight = 100,000 N
Density = 1.2 kg/m³
Gravitational acceleration (g) ≈ 9.8 m/s²
\(Volume = \frac{100000 N}{(1.2 kg/m^3) \times (9.8 m/s^2)}\)
Volume ≈ 8,680.56 m³
Therefore, if the density of air were a constant 1.2 kg/m³, the thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is approximately 8,680.56 meters.

Why are thire only large impact craters on Venus?

B. There are only large impact craters on Venus because geological activity erodes impact craters over time.
C. There are only large impact craters on Venus because most smaller asteroids and meteors have been cleared out of the inner solar system over the last few billion years.
D. There are only large impact craters on Venus because the weather on the planet erodes impact craters over time.
E. There are actually impact craters of all sizes on the surface of Venus.
Answers
Venus has large impact craters due to the absence of erosive forces and the survival of only the largest meteors and asteroids through its thick atmosphere.
Option (A) is correct.
Venus, known as the sister planet of Earth, is characterized by its thick, corrosive atmosphere and extreme temperatures. Its surface lacks water and volcanic activity, and is instead marked by numerous large impact craters. This is due to the absence of erosive forces, like water, which would have gradually eroded the craters over billions of years. The craters formed on Venus as a result of asteroid and comet impacts over the past 4.6 billion years. However, the impact process on Venus differs from that on Earth. Venus' thick atmosphere burns up most smaller meteorites and asteroids upon entry, allowing only the largest ones to survive their descent. Consequently, only the large impact craters remain visible on the planet's surface today. Therefore, option (A) is correct. In summary, Venus bears only large impact craters as a consequence of the survival of substantial meteors and asteroids through its thick and corrosive atmosphere.

A 28 g ball of clay traveling east at 3.2 m/s collides with a 32 g ball of clay traveling north at 2.8 m/s
Answers
The two balls will move together at a velocity of 2.987 m/s at an angle between east and north after the collision.
When the 28 g ball of clay traveling east at 3.2 m/s collides with the 32 g ball of clay traveling north at 2.8 m/s, the two balls will stick together due to the conservation of momentum.
To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum before the collision is equal to the total momentum after the collision.
The momentum of an object is given by the product of its mass and velocity. Therefore, the momentum of the 28 g ball of clay before the collision is (28 g) * (3.2 m/s) = 89.6 g·m/s east, and the momentum of the 32 g ball of clay before the collision is (32 g) * (2.8 m/s) = 89.6 g·m/s north.
After the collision, the two balls stick together, so their total mass is 28 g + 32 g = 60 g. The momentum of the combined mass can be calculated by adding the momenta of the individual balls before the collision.
Therefore, the total momentum after the collision is 89.6 g·m/s east + 89.6 g·m/s north = 179.2 g·m/s at an angle between east and north.
To calculate the velocity of the combined balls after the collision, divide the total momentum by the total mass: (179.2 g·m/s) / (60 g) = 2.987 m/s.

Answers
The final speed of the cart on the floor surface is 14.28m/sec if a grocery cart weight is 60.8N
Since, we need to find the final speed of the object and distance is given, it means that we can use third equation of motion, which is
v² - u² =2aS where v is the final velocity and u is the initial velocity,a is the acceleration of the object and S is the displacement of the object.
Since weight =60.8N,=W=mg
=>60.8=m×9.8
=>m=60.8/9.8
=>m=6.204kg
Now,we have mass and force,so we need to find the acceleration of cart which is given by the formula
=>F=ma
=>58.1N=6.204×a
=>a=(58.1)/6.204
=>a=9.364m/sec²
Now, we have acceleration and initial velocity of cart=0,so we can apply the third equation of motion
=>v²-0= 2×9.364×10.9
=>v²=204.155
=>v=√204.155
=>v=14.28m/sec

Speed of the bricks at the top of hill is 6.26 m/s. c.)speed of the bricks at the top of hill is 14.14 m/s. d)minimum compression of spring necessary to get to the top of hill is 6.26 m. e) speed of the bricks at the top of hill with 2 m of initial compression and 15% energy dissipation is 13.04 m/s.
What is energy?The capacity or power to do work, such as the capacity to move an object by application of force is called energy.
Initial potential energy of compressed spring is:
Ep = 1/2 kx^2 = 1/2 * 500 N/m * (2 m)^2 = 1000 J
k is spring constant, x is compression of the spring, and J is unit of energy in joules.
Final potential energy of the bricks is:
Ep = mgh = 100 N * 9.81 m/s^2 * 2 m = 1962 J
Ep = Ep
1/2 kx^2 = mgh
v = sqrt(2gh) = sqrt(2 * 9.81 m/s^2 * 2 m) = 6.26 m/s
Therefore, the speed of the bricks at the top of the hill is 6.26 m/s.
c. Initial potential energy of compressed spring is: 1000 J
Ek = Ep = 1000 J
Kinetic energy of the bricks is given by:
Ek = 1/2 mv^2
1000 J = 1/2 * 100 N * v^2
v = sqrt(200 / 1) = 14.14 m/s
Therefore, the speed of the bricks at the top of the hill is 14.14 m/s.
d. As, Ep = m g h
where m is mass of the bricks, g is acceleration due to gravity, and h is height of the hill.
Ep = 100 N * 9.81 m/s^2 * 2 m = 1962 J
Ep = 1/2 kx^2 = 1962 J
1/2 * 500 N/m * x^2 = 1962 J
x = sqrt(2 * 1962 J / 500 N/m) = 6.26 m
Therefore, the minimum compression of the spring necessary to get to the top of the hill is 6.26 m.
e. If 15% of the energy is dissipated through friction, final kinetic energy of the bricks at the top of the hill will be 85% of initial potential energy of the compressed spring. Therefore,
0.85 * 1000 J = 1/2 mv^2
v = sqrt(170 / 1) = 13.04 m/s
Therefore, the speed of the bricks at the top of the hill with 2 m of initial compression and 15% energy dissipation is 13.04 m/s.

The best way is to use a hand crank such as a hand cranked flashlight or radio because it is easy to power enough energy for a short amount of time.
The concept of an energy capturing rocking chair is creative, its practicality and effectiveness for a rescue team might be limited due to the relatively low energy output, efficiency concerns, and availability of more efficient alternatives.
The rescue team's energy needs, the specific environment they operate in, and the available resources would need to be carefully considered before implementing such a solution.
An "energy capturing rocking chair" is an interesting concept, but its effectiveness for a rescue team would depend on several factors.
Pros:
Renewable Energy Source: If the rocking chair is designed to convert the kinetic energy generated by rocking into electrical energy, it could provide a renewable energy source for charging devices or powering equipment in remote or emergency situations where traditional power sources might be unavailable.
Low Maintenance: Rocking chairs are relatively simple mechanical devices, which means they could potentially have lower maintenance requirements compared to more complex energy generation systems.
Portable and Compact: Rocking chairs are typically portable and don't require a large footprint, making them suitable for deployment in various environments, including temporary shelters or remote locations.
Human-Powered: Rescue team members could generate energy while resting or waiting, which could be especially useful during downtime.
Cons:
Energy Output: Rocking chairs might not generate a significant amount of energy. The energy output from rocking would likely be relatively low compared to more efficient energy generation methods.
Efficiency: Converting mechanical motion into electrical energy involves energy losses due to friction and other factors. The overall efficiency of the energy conversion process could be a limitation.
Time and Effort: Rescue team members' primary focus is on performing their duties effectively. Spending significant time and effort rocking in chairs to generate energy might divert their attention from critical tasks.
Limited Applicability: The energy generated from rocking chairs might be suitable for low-power devices like lights, radios, or small electronics. However, it may not provide sufficient power for high-energy-demand equipment like communication systems, medical devices, or power tools.
Alternative Solutions: There are other portable and renewable energy solutions available, such as solar panels, portable wind turbines, or hand-crank generators, which might be more efficient and practical for a rescue team.

Engine and brake traction control systems keep you from having to replace the _______ as often.
Answers
Engine and brake traction control systems keep you from having to replace the brakes as often.
The traction control uses the brakes and the torque of the engine to control the spin of the driving wheels.
As maximum of the burden is pulled up by the engine and brake traction control systems, this helps in keeping the brakes of the car protected.
The engine and the brake traction control systems provide stability as well as maximum traction due to which the brakes do not have to be replaced as often.
Brake traction control detects braking force to the wheels that need it hence increasing the torque on that particular wheel.

The absolute brightness of a star depends on its _____.
a. size and temperature
b. distance an temperature
c. color and temperature
d. distance and color
Answers
Option A. The absolute brightness of a star depends on its size and temperature
What is the absolute brightness of a star
The absolute brightness of a star is the amount of light it emits at a standard distance from Earth, regardless of how far away it actually is.
The size and temperature of a star are the primary factors that determine its absolute brightness. The size of the star affects the amount of light it emits, with larger stars emitting more light. The temperature of a star affects the color of the light it emits, with hotter stars emitting bluer light and cooler stars emitting redder light. Both of these factors play a significant role in determining a star's absolute brightness.
Distance and color can also affect a star's brightness, but in different ways. The distance of a star affects its apparent brightness as seen from Earth, but not its absolute brightness. The color of a star can provide information about its temperature and composition, but does not directly determine its absolute brightness.
