Answer:

50m; 0m/s.

Explanation:

Given the following data;

Initial velocity = 20m/s

Acceleration, a = - 4m/s²

Time, t = 5secs

To find the displacement, we would use the second equation of motion;

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

Substituting into the equation, we have;

\( S = 20*5 + \frac {1}{2}*(-4)*5^{2}\)

\( S = 100 + (-2)*25\)

\( S = 100 - 50\)

Displacement, S = 50m

Next, to find the final velocity, we would use the third equation of motion;

\( V^{2} = U^{2} + 2aS \)

Where;

Substituting into the equation, we have;

\( V^{2} = U^{2} + 2aS \)

\( V^{2} = 20^{2} + 2(-4)*50 \)

\( V^{2} = 400 - 400\)

\( V^{2} = 0\)

Final velocity, V = 0m/s

Therefore, the displacement of the bus is 50m and its final velocity is 0m/s.

Explanation:

The speed of the block of mass m after the cord is burned after the block of mass 3m moves to the right with a speed of 2.00 m/s is -6 m/s.

To find the speed of the block of mass m after the cord is burned, we can use the conservation of momentum principle.

Step 1: Define the initial and final momenta.

Initially, both blocks are at rest, so the total momentum is zero. After the cord is burned, the block of mass 3m moves to the right with a speed of 2.00 m/s, and we need to find the speed of the block of mass m.

Step 2: Apply conservation of momentum.

The total momentum before the cord is burned equals the total momentum after the cord is burned.

Initial Momentum = Final Momentum

0 = m × v_m + 3m × 2.00 m/s

Step 3: Solve for the speed of the block of mass m (v_m).

0 = m × v_m + 6m

-6m = m × v_m

Divide both sides by m:

v_m = -6 m/s

Thus, the speed of the block of mass m after the cord is burned is -6 m/s. The negative sign indicates that it moves in the opposite direction to the block of mass 3m.

a. The initial velocity of the pumpkin is approximately 63.44 feet per second. b. The total time that the pumpkin is in the air is approximately 8 seconds.

a. To calculate the initial velocity of the pumpkin, we can use the kinematic equation for projectile motion:

s = ut + (1/2)gt^2

Where:

s = distance traveled (400 feet)

u = initial velocity (unknown)

t = time of flight (unknown)

acceleration due to gravity (g) = 32.2 ft/s^2)

Equation to solve for u:

u = (s - (1/2)gt^2) / t

Substituting the given values, we have:

u = (400 ft - (1/2)(32.2 ft/s^2)(8 s)^2) / 8 s

u ≈ 63.44 ft/s

b. The total time that the pumpkin is in the air can be determined using the equation:

t = 2u / g

Substituting the values, we get:

t = 2(63.44 ft/s) / (32.2 ft/s^2)

t ≈ 8 s

a. The initial velocity of the pumpkin is approximately 63.44 feet per second.

Answer: A wavelength is how long ONE wave is. First divide the distance of the whole diagram by the number of waves. you will get 2m. This is the answer.

Usain Bolt's remarkable feat of running 100 meters in 9.58 seconds translates to an impressive speed of approximately 10.44 meters per second. This means that for every second that elapses, Bolt covers a distance of approximately 10.44 meters.

To calculate the speed, we use the formula: Speed = Distance / Time

In this case, the distance is 100 meters and the time taken is 9.58 seconds. By dividing 100 meters by 9.58 seconds, we find that Bolt's average speed over the course of 100 meters is approximately 10.44 meters per second. It's important to note that Bolt's speed may not remain constant throughout the entire 100-meter sprint.

Explanation:

(a) The equilibrium temperature of the system is 0°C.

(b) There is no unmelted ice when the system reaches equilibrium.

The three ice cubes have a total mass of 3 * 111.0 g = 333 g. The water has a mass of 0.840 kg = 840 g. The specific heat capacity of water is 4.184 J/g°C. The latent heat of fusion of water is 333.55 J/g.

When the ice cubes are added to the water, the ice cubes will absorb heat from the water until they reach 0°C. Once the ice cubes reach 0°C, they will begin to melt. The heat required to melt the ice cubes will come from the water.

The water will continue to lose heat until all of the ice cubes have melted. The total heat required to melt the ice cubes is:

Q = m * Lf

Q = 333 g * 333.55 J/g

Q = 111,476 J

The total heat lost by the water is:

Q = m * c * ΔT

Q = 840 g * 4.184 J/g°C * (21.0°C - 0°C)

Q = 75,056 J

Since the heat lost by the water is equal to the heat required to melt the ice cubes, the equilibrium temperature of the system is 0°C. At 0°C, the water will be in equilibrium with the ice. There will be no unmelted ice when the system reaches equilibrium.

The existence of coal beds in Antarctica is evidence that the region once experienced significant warming and was home to vast amounts of plant life.

One of the earliest hypotheses put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift.

The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. He referred to it as continental drift.

What is known about Antarctica's changing climate is that it didn't begin to cool until roughly 34 million years ago, when the continent was severed from the others which supports Continental Drift theory.

The clocks on the space vehicle will gain approximately 0.0031 day or 4.5 minutes per day compared to Earth-based clocks due to time dilation. This means that if the space vehicle travels for a year, its clocks would be ahead of Earth-based clocks by approximately 26 hours.

According to the theory of relativity, time is not absolute and can vary depending on the relative motion of two observers. When an object travels at a high velocity relative to another object, time dilation occurs, which means that time appears to move slower for the moving object. In the case of a space vehicle traveling at a high velocity relative to the Earth, its clocks will appear to move slower than Earth-based clocks.

To calculate the exact amount of time dilation, we need to use the formula:

Δt' = Δt * √(1 - v²/c²)

where Δt' is the time interval measured by the moving clock, Δt is the time interval measured by the stationary clock (Earth-based clock), v is the velocity of the moving clock relative to the stationary clock, and c is the speed of light.

Assuming that the space vehicle is traveling at a velocity of 27,500 km/h, which is about the speed of the International Space Station (ISS), we can calculate the time dilation as follows:

Δt' = Δt * √(1 - v²/c²)
Δt' = 1 day * √(1 - (27,500 km/h)²/(299,792 km/s)²)
Δt' = 1 day * √(1 - 0.0002525)
Δt' = 1 day * √(0.9997475)
Δt' = 0.999873 day or 23.9969 hours

Therefore, the clocks on the space vehicle will gain approximately 0.0031 day or 4.5 minutes per day compared to Earth-based clocks due to time dilation. This means that if the space vehicle travels for a year, its clocks would be ahead of Earth-based clocks by approximately 26 hours.

Unless a light ray comes into contact with a surface or enters a different material, it travels in a​ straight line.

When light enters a medium with a different speed or transitions from a fast to a slow medium, refraction occurs. According to Snell's law, if a light ray is incident ordinarily on the surfaces, then deviating from the normal will always lengthen the travel time.

Theoretically, sine (angle of incidence)*index of refraction of the incident media = sine (angle of refraction)*index of refraction of the refractive medium

Sine (0)=0 because the angle of incidence is 0 degrees.

Answer:

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. ... When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet.

Explanation:

Explanation:

The electric motor, generator, and transformers all work on the principle of electromagnetic induction. The electric motor converts electrical energy into mechanical work. The electric generator works in the opposite way of an electric motor. It converts mechanical work into electrical energy. The source of mechanical energy varies from a wide range of hand cranks and combustion engines.

An electric generator works on the principle of electromagnetic induction phenomenon. According to it, whenever a coil is rotated between the poles of a magnet, an induced current is set up in the coil, whose direction is given by Fleming’s right-hand rule. The principle of working of a generator is such that the flow of electric charges can be induced by moving an electrical conductor in a magnetic field. Moving the conductor in the magnetic field or stationary conductor in a fluctuating magnetic field produces a voltage difference between the two ends of the wire (electrical conductor), thus producing an induced current.

The value of K is x > A₀ / 3 for indicating that there are more moles of b than a at equilibrium.

The equilibrium constant, represented by K, is a measure of how much the concentration of the reactants at equilibrium, which is the state of balance in which the forward and backward reaction rates are equal.

There are two things to keep in mind here:

a and b are gas molecules and the stoichiometric coefficient of a is 1, while that of b is 2.

Let us calculate the value of K for this reaction:

K = [B]^2 / [A]

In this equation, [B] refers to the concentration of b at equilibrium, whereas [A] refers to the concentration of a at equilibrium.

Therefore, the K value would indicate that there are more moles of b than a at equilibrium when:

[B]²/[A] > 1

This is due to the fact that K can only be greater than 1 when there is more product at equilibrium. This suggests that there are more moles of B at equilibrium than there are moles of A.

Here is the calculation of K and the solution:

K = [B]²/[A]

Let x be the number of moles of A that react to generate the number of moles of B at equilibrium, which is 2x. This is due to the fact that the stoichiometric coefficient of B is twice that of A.

B(x) = 2x

We can conclude that,

[A] = [A₀] - x

[B] = [B₀] + 2x

Now let us insert these values into the expression for K.

K = [B]²/[A]

K = (2x)² / (A₀ - x)

K = 4x² / (A₀ - x)

As we saw earlier, K is greater than 1 if and only if:

[B]²/[A] > 1

K = 4x² / (A₀ - x) > 1

x² > (A₀ - x) / 4

x > √[(A₀ - x) / 4

The final answer is:

2x > A₀ - x

x > A₀ / 3.

Firstly, the gravitational pull would drastically increase. Black holes have an extremely strong gravitational field, so the planets, asteroids, and other objects in the solar system would experience a much stronger gravitational force.  Secondly, the Sun's energy output would cease. The Sun is a main-sequence star that produces energy through nuclear fusion. A black hole, on the other hand, does not emit any significant amount of light or energy itself.  Lastly, the event would likely have catastrophic consequences for life on Earth. The sudden disruption in gravitational forces and the loss of the Sun's energy would disrupt ecosystems, temperature regulation, and the availability of sunlight for photosynthesis. The sudden increase in gravitational forces could also lead to gravitational disturbances and potentially dangerous orbital changes for the planets.
