Which kind of energy is greater? Potential or kinetic energy?

2 answers:

5 0

Answer: it depends potential energy is the build up of kinetic energy like going to the top of a roller coaster. kintic is the use of the potential energy like going down the roller coaster so depends how much energy one another give :)

Hope this helps you out :)

Answer:

Explanation:

The question has no set meaning. Suppose you take a rock to the top of a building. You put the rock over the edge of the building. You don't drop it yet. The potential energy is greatest for the rock under this condition. The kinetic energy is 0 because the rock is not moving.

Now you let the rock go. As it falls, it looses distance to the ground which means that the Potential energy is nearing 0. The Kinetic energy is picking up because the rock is moving faster.

At the bottom of the rock's journey just before it hits the ground, the KE is at a maximum and the PE is nearly 0.

If a student took seven science classes, his/her at score would be 1200.

<h3>What is a graph?</h3>

A graph is a relationship in which data is presented on the axes of cartesian coordinates. The presentation of the graph must be such that it is easy to read off the graph.

Now we can see that the graph is a plot of SAT scores versus the number of science classes that students take. In this case, the slope would tell us the score per subject of a student in the SAT.

a) The mathematical model that re[resents this graph is;

y =100x + 500

b) The slope of the graph must be obtained by the use of two points thus;

m = y2 - y1/x2 - x1

m = 600 - 500/1 - 0

m = 100

c) Using the relation;

y = mx + c

m = 100

c = 500

y = 100(7) + 500

y = 1200

Thus if a student took seven science classes, his/her at score would be 1200.

What energy comes from a rining bell

Harrizon [31]

Answer: Sound Energy

Sound Energy

Explanation:The vibrations produced by the ringing bell causes waves of pressure that travel or propagate through the medium that is air. Sound energy is a form of mechanical energy that is generally associated with the motion and position of the ringing bell.

Name three types of stress that a force can cause inside an object?

Anton [14]

Answer:

Explanation:

Stress is the force applied to a rock and may cause deformation. The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries.
