Answer:

Please find the answer in the explanation.

Explanation:

Given that the actual speed of the car at the top of the hill is 20.0m/s. What is the reason for this difference in velocity?

Speed is a scalar quantity that is, it has only magnitude but no direction.

While velocity is a vector quantity, that is, it has both magnitude and direction.

If the actual speed of a car is 20 m/s, that is the magnitude of the speed only without direction.

The velocity will therefore be of the same magnitude but with addition of direction. Either west, east or north south.

Aerobic respiration is used by an organism because it needs to generate  energy and has availability of oxygen. Option D is correct.

Aerobic respiration is a cellular process that occurs in the presence of oxygen and involves the breakdown of glucose to produce ATP (adenosine triphosphate), which is the main energy currency of cells. Organisms carry out aerobic respiration to generate energy needed for various cellular functions such as growth, metabolism, movement, and reproduction.

Oxygen acts as the final electron acceptor in the electron transport chain of aerobic respiration, allowing for the efficient production of ATP through oxidative phosphorylation. If an organism has access to oxygen, it would preferentially use aerobic respiration to produce ATP because it is more efficient in generating energy compared to other forms of cellular respiration.

Hence, D. is the correct option.

If a baseball dropped from the roof of a tall building takes 3.1 seconds to hit the ground, the height of the building would be 47.1 m.

According to Newton's second law of motion,

\(s=ut+\frac{1}{2}at^{2}\)

Where, s is the distance covered by the body, u is its initial velocity, t is the time taken by the body, and a is the acceleration of the body.

Here, the distance covered will be equal to the height of the building.

Since the ball was dropped, its initial velocity will be zero.

Also, the acceleration of the ball is the acceleration due to gravity, \(g=9.8 m/s^{2}\).

Substituting the values,

\(h=0+\frac{1}{2} gt^{2}\)

\(h=\frac{1}{2} \times9.8\times3.1^{2}\)

\(h=47.1m\)

Therefore, the height of the building would be 47.1 m.

Mugabe gained power by using political strategies, forming alliances, and exploiting his status as a liberation hero within ZANU-PF.

Robert Mugabe, the former president of Zimbabwe, was able to build power through a combination of political strategies and alliances. One key factor was his involvement in the liberation struggle against white minority rule in Rhodesia (now Zimbabwe).

Mugabe emerged as a prominent figure within the Zimbabwe African National Union (ZANU) party, which later merged with the Zimbabwe African People's Union (ZAPU) to form the Zimbabwe African National Union - Patriotic Front (ZANU-PF). Mugabe's role as a liberation hero and his ability to mobilize support among the majority black population of Zimbabwe gave him a strong power base.

Within ZANU-PF, Mugabe strategically positioned himself and gained influence by forming alliances and outmaneuvering rivals. He rose to become the party's leader and played a key role in negotiating the Lancaster House Agreement in 1979, which paved the way for Zimbabwe's independence in 1980. Mugabe became the country's first prime minister and later transformed the position into an executive presidency, consolidating his authority.

Mugabe maintained power through various means, including controlling key institutions such as the military, intelligence agencies, and the ruling party. He also utilized patronage networks, distributing resources and positions to loyal supporters within the party and government. Mugabe's policies, such as the controversial land reform program, further solidified his power base by appealing to nationalist sentiments and redistributing land from white farmers to black Zimbabweans.

However, Mugabe's consolidation of power was also marked by authoritarianism, human rights abuses, and a declining economy. His grip on power faced challenges over the years, including opposition movements, internal party factions, and economic crises. Ultimately, his rule came to an end in 2017 when he was ousted from power following a military intervention.

When the output does not meet the equilibrium quantity in a market, a situation known as disequilibrium occurs. Disequilibrium refers to a state where there is an imbalance between the quantity demanded and the quantity supplied of a particular good or service. In this situation, two possibilities can arise: Excess Demand and Excess Supply.

Excess Demand: If the quantity demanded exceeds the quantity supplied, it creates a situation of excess demand or a shortage. Consumers are willing to purchase more of the product at the prevailing price than what is available in the market. This can lead to increased competition among consumers, rising prices, and a potential loss of potential sales for suppliers.

Excess Supply: On the other hand, if the quantity supplied exceeds the quantity demanded, it creates a situation of excess supply or surplus. Suppliers are producing more of the product than what consumers are willing to purchase at the prevailing price. This can lead to price reductions, decreased profitability for suppliers, and a buildup of unsold inventory.

In either case, the market is not in equilibrium, and there is a discrepancy between the quantity demanded and the quantity supplied. In response to disequilibrium, market forces such as price adjustments, changes in consumer behavior, or shifts in production levels may occur in an attempt to restore equilibrium.

Answer:

A force that tries to slow things down that are moving through air. It is a type of friction. Air resistance and water resistance are both sometimes called drag.

The speed of the projectile when it strikes the ground below is approximately 620.6 m/s.

We can use the kinematic equations of motion to solve this problem.

First, we can find the time it takes for the projectile to hit the ground using the vertical motion equation:

y = vi*t + (1/2)at²

where y is the vertical displacement (in this case, the initial height of the cliff), vi is the initial vertical velocity (in this case, zero), a is the acceleration due to gravity (-9.8 m/s^2), and t is time.

Plugging in the values, we get:

265 m = 0t + (1/2)(-9.8 m/s²)*t²

Solving for t, we get:

t = √((2*265 m) / (9.8 m/s²)) = 8.25 s

Next, we can find the horizontal displacement of the projectile using the horizontal motion equation:

x = v*t

where x is the horizontal displacement, v is the initial horizontal velocity, and t is time.

Since the initial velocity is at a 45-degree angle, we can break it down into its horizontal and vertical components:

v_initial_x = v_initial*cos(45 degrees) = 350 m/s * cos(45 degrees) = 247.5 m/s

v_initial_y = v_initial*sin(45 degrees) = 350 m/s * sin(45 degrees) = 247.5 m/s

The horizontal displacement can now be calculated as:

x = v_initial_x * t = 247.5 m/s * 8.25 s = 2041.9 m

Finally, we can find the speed of the projectile when it hits the ground using the total velocity equation:

v_final² = v_initial_x² + v_initial_y² + 2ay

where v_final is the final velocity, v_initial_x and v_initial_y are the horizontal and vertical components of the initial velocity, and y is the vertical displacement.

Plugging in the values, we get:

v_final² = (247.5 m/s)² + (350 m/s)² + 2*(-9.8 m/s²)*(265 m)

Solving for v_final, we get:

v_final = √((247.5 m/s)² + (350 m/s)² + 2*(-9.8 m/s²)*(265 m)) = 620.6 m/s

Therefore, the speed of the projectile when it strikes the ground below is approximately 620.6 m/s.

Explanation:

\(p1 \times v1 = p2 \times v2 \)

\(p1 = initial \: pressure \\ v1 = initial \: volume \\ p2 = final \: pressure \\ v2 = final \: volume\)

You're looking for p2. So, divide both sides by v2...

\( \frac{p1 \times v1}{v2} = p2\)

volume of a cylinder is

\(h \times \pi \: \times {r}^{2} \)

let's assume r = 1

\( \frac{p1 \times (20cm \times \pi)}{(60cm \times \pi)} = p2\)

the Pi's cancel out, the 20/60 can be reduced to 1/3.

So you end up with

\(p1 \times \frac{1}{3} = p2\)

or as the book shows....

\( \frac{1}{3} p\)

1. Kinetic energy is the energy possessed by a body due to its motion. Potential energy is the energy possessed by a body due to its position or state. Kinetic energy can be transferred from one object to another, in case of collisions. Potential energy cannot be transferred. Thus, the potential energy is stored in the object due to its position, whereas the kinetic energy is possessed by an object due to motion.

Eg: A ball kept on the edge of the table possesses potential energy due to its height, whereas a ball falling down from the table will possess kinetic energy due to its motion.

2. The formula for Kinetic energy is as below: This means that kinetic energy is directly proportional to mass as well as velocity. But it is proportional to 1 unit of mass and a square of velocity. Hence, velocity has a greater effect on kinetic energy.…show more content…

3. The equation for kinetic energy is: .

Let’s calculate the kinetic energy of a 40 kg object traveling 15 m/s.

Solution: mass= 40kg, velocity= 15 m/s, so putting these numbers into the kinetic energy equation,

Now, let’s calculate the kinetic energy of a 40 kg object traveling 30 m/s.

Solution: mass= 40kg, velocity= 30 m/s, so putting these numbers into the kinetic energy equation, Thus, when we double the velocity of an object, its kinetic energy increases by four times. Hence the velocity of an object has more impact on kinetic energy than the mass of an object.

The light from the green glow stick held by the Olympic sprinter will appear redshifted.

The phenomenon of redshift occurs when the source of light is moving away from the observer. In this case, as the sprinter is running towards you, the distance between you and the glow stick is decreasing over time. This decrease in distance causes a Doppler shift in the frequency of the light emitted by the glow stick.

Since the light is redshifted, its wavelength increases and the frequency decreases compared to its original emitted frequency. As a result, the light that reaches your eyes appears more towards the red end of the visible spectrum.

It is important to note that the color of the glow stick itself remains the same, but due to the relative motion between the source (the sprinter) and the observer (you), the light undergoes a change in frequency and appears redshifted.

This phenomenon is similar to the redshift observed in cosmology, where the light from distant galaxies appears to be redshifted due to the expansion of the universe.

The set of waves that travels through the Earth's interior consists of seismic waves.

Seismic waves are waves of energy that are generated by various sources, such as earthquakes, volcanic activity, or human-made explosions. These waves propagate through the Earth's layers, providing valuable information about the Earth's interior structure.

There are two primary types of seismic waves: P-waves (primary waves) and S-waves (secondary waves). P-waves are compressional waves that can travel through solids, liquids, and gases. They are the fastest seismic waves and are capable of traveling through the Earth's interior in a straight line. S-waves, on the other hand, are shear waves that can only travel through solids. They are slower than P-waves and can only propagate through the solid layers of the Earth.

In addition to P-waves and S-waves, there are also surface waves, which travel along the Earth's surface and are responsible for the most significant damage during earthquakes. Surface waves include Rayleigh waves and Love waves.
