The process of converting one form of energy into another is referred to as energy conversion.

The process of converting energy from one form to another is referred to as energy transformation.  Energy is a quantity in physics that gives the capacity to perform labour or move (e.g., lifting an object) or provides heat. Energy, in addition to being converted, is transferable to a different location or object, but it cannot be created or destroyed, according to the law of conservation of energy.

Many sources of energy can be employed in natural processes or to give a service to society, such as heating, refrigeration, lighting, or mechanical work to power machines. For example, to heat a house, the furnace burns fuel, converting its chemical potential energy into thermal energy, which is then delivered to the house.

The presented statement estimates that the subway train traveled a total of 1798.18 meters.

The degree which an object's positioning changes in any direction. The inverse of the distance reached to the time needed to travel that distance is known as speed. Given that it only has to have a direction and no magnitude, tempo is a synthesis number.

initial acceleration (a1)= 1.60m/s^2

time (t1) = 14s

time for constant speed = 70s

deceleration (a2) = 3.50 m/s^2

total distance = ?

Velocity - Time Graph

We need to create the velocity-time graph in order to adequately address this problem.

By summing the separate areas of the figures, the distance may be computed.

Area of first triangle.

1/2b*h

However, this train's speed would be indicated by its height.

Velocity = acceleration * time

Velocity = 1.6 * 14 = 22.4m/s

The triangular is 22.4 meters tall.

Let's swap the variables and calculate the area.

A1 = 1/2*14*22.4 = 157.5m

The perimeter of the rectangle is the following distance that we would measure.

A = L*W

L = 22.4

W = 70

A = 22.4 * 70 = 1568m

The last triangle is the distance that has to be calculated.

Triangle area is equal to 1/2b*h.

However, we are unsure exactly how long the slowdown took on a base (time) basis.

Use the link between velocity, acceleration, and time.

Acceleration = velocity/time

time = velocity/acceleration

time = 22.4/3.5

time = 6.4s

Replace the values and find the Area by substituting

A = 1/2*b*h

A = 1/2 *6.4*22.4

A = 72.68m

The train travels a total of 157.5m Plus 1568m + 72.68m.

Distance = 157.5 + 1568 + 72.68

Velocity is a vector quantity that refers to the rate of change of an object's position with respect to time. It measures the speed of an object in a specific direction. The unit of velocity is meters per second (m/s) or miles per hour (mph) depending on the measurement system being used. In physics, velocity is considered a fundamental concept that is used to describe the motion of objects in the physical world.

Velocity is calculated by dividing the change in position by the change in time. For example, if an object moves 10 meters in 2 seconds, its velocity would be 5 m/s in the direction of the movement. It is important to note that velocity is not the same as speed, which is only concerned with the magnitude of the velocity and not the direction.

The new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L. The sound intensity level, L, is a measure of the sound wave's power per unit area, relative to a reference value. It is expressed in decibels (dB).

The sound intensity level, L, is defined as 10 log (I/I0), where I is the intensity of the sound wave and I0 is the reference intensity. To find the new sound intensity level if the pressure amplitude is increased by a factor of 10.0, we first need to find the new intensity of the sound wave.

The sound intensity, I, is proportional to the square of the pressure amplitude, P:

I ∝ P²

So if the pressure amplitude is increased by a factor of 10.0, the intensity will be increased by a factor of 10.0² = 100.0. The new intensity, I', is given by:

I' = 100.0I

Using this new intensity, we can find the new sound intensity level:

L' = 10 log (I'/I0) = 10 log (100.0I/I0) = 10 log (100.0) + 10 log (I/I0) = 20 + L

So the new sound intensity level, L', will be 20 dB higher than the original sound intensity level, L.

In this calculation, we use the fact that log (ab) = log a + log b, where a and b are positive numbers.

So, if the pressure amplitude were increased by a factor of 10, the new sound intensity level would be 20 dB higher than the original sound intensity level. This relationship between pressure amplitude, intensity, and sound intensity level is important for understanding the physical properties of sound waves and for comparing the strength of different sounds.

The velocity of an object under constant acceleration (in this case, due to gravity) can be found using the equation

v = v_0 + a * t

where v is the final velocity, v_0 is the initial velocity,

a is the acceleration (in this case, due to gravity,

where an is the acceleration brought on by gravity (-9.8 m/s2), vi is the initial velocity, t is the time (1.3 s), and h is the window's height (2 m).

Rearranging the equation to solve for vi:

vi = sqrt(2 * a * h / t^2)
