Is energy conserved when a ball falls to the ground

Answers

Answer 1

Answer: Of course. You've certainly heard that energy is conserved, period. Why would you think it's different when a ball falls to the ground ? ?

a Pontiac trans-am, initially at rest accelerates at a constant rate of 4.0 m/s squared for six seconds how fast will the car be traveling a T equals six seconds

Answers

use formula: a= Vf-Vi/t
rearrange: Vf=at
solve: Vf= 4.0m/s squared x 6s
Vf = 24 m/s --> sigdigs
Vf = 2.4 x 10^1 m/s

Explain the relationship between heat and physical state of a substance.

Answers

Answer:

When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

The volume of a gas is 605 liters at 27.0°C. The new temperature is -3.0°C. What is the new volume?-67.2 L
-545 L
-672 L
-5450 L

Answers

According to the Charle's law, the new volume of gas is -545 L when the pressure is constant.

What is Charle's law?

Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.

The graph of volume versus temperature is a straight line passing through the origin.It was formulated in the year 1780 by scientist Jacques Charles.

The new volume of gas is obtained by substituting values in the formula V₂=605×(-270)/300=-545 L.

Thus, the new volume of gas is -545 L.

#SPJ2

from p1v1/t1 = p2v2/t2
pressure unchanged ... cancelled out
v1=605 , t1=27C = 300K,
t2=-3C = 270K
***remember temperature must be in Kelvin
we got
605/300 = v2/270
v2 = 545

a. What kind of curve did you obtain?
b. What is the relationship between the variables?
c. What do you expect the distance traveled to be after 45 s?
d. How much time is required for the object to travel 74 m?

Answers

You would get perhaps a very slight curve upward (assuming distance is plotted along the x axis and time up the y axis), as the distance increases by about 10 each time, and usually the time in seconds increases by 1, but occasionally the time increases by 2
Not sure about the relationship, I guess you could call it a positive correlation, if that's the kind the question is looking for
I'd expect the object to have travelled 334m after 45 seconds, assuming that there are no more jumps in the data, because 12*4 = 48, so 91*4 = 364, then because 10m = 1s, subtracting 3s to get down to 45s means subtracting 30m, so as to get 334m. Honestly though, for a better result, you would need to draw out the graph and calculate from there to get a better answer
74m, being between 70 and 80m, means the time needs to be between 10 and 11s
I'd expect it to be 10.4s, because as we said earlier 10m = 1s, so 4m would equal 0.4s
Hopefully that helps you, I know the answers aren't of the best quality (I know I'm not particularly happy with some of them), but that's the best I can do for you on short-notice :)

A change from one form of energy into another is calleda. gravitational potential energy.
b. work.
c. conservation of energy.
d. an energy transformation.

Answers

A change from one form of energyinto another is called conservation of energy. The answer is letter C. youcannot create something and destroy it. An example is eating food. You can seefood as how as a physical being. However, when you eat the food, the digestiveenzymes in your stomach helps break down the food into smaller form. The chemicalenergy in the food is being changed into mechanical energy. You need food toperform the necessary activities in your life.

Answer: d. an energy transformation.

Explanation:

Gravitational potential energy is the energy possessed by an object by virtue of its position.

Work is defined as the force leading to displacement of the point of application in the direction of the force.

Law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.

Energy transformation occurs when one form of energy is converted into another form. For example : A body in rest possess potential energy and when it moves potential energy is converted into kinetic energy.

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct? -Brody is correct because the wave involves an input of energy. -Ethel is correct because energy is not carried from one place to another. -Brody is correct because the pattern repeats. -Ethel is correct because the motion has no pattern. Also... Khalad is measuring the amplitude of a wave. What can be known about this wave? -It is a sound wave. -It is a transverse wave. -It is an electromagnetic wave. -It is a mechanical wave.

Answers

In the first question, the answer would be the statement 'Brody is correct because the wave involves an input of energy'. The hand wave involves an input of energy and this energy is repeated and is carried from one place to another.

For the next question, the answer would be 'it is a transverse wave' because all are transverse waves.

Answer:

Ethel is correct because energy is not carried from one place to another.

It is a transverse wave.

Explanation:

During the propagation of waves from one point or place to another, energy is being transferred. Thus, when one's hand is being waved, there is no transfer of energy from one point to another. Therefore, Ethel is right while Brody is wrong.

A transverse wave is known as a type of wave that the direction of propagation is perpendicular to the vibration of the medium. Therefore, the wave is a transverse wave.
