-- Kinetic energy is the energy of mass in motion. The amount is determined by the mass of whatever is moving, and its speed.
-- Potential energy is the energy that's stored up in some form, not being used yet but ready to be used when you want it.
For example, one form of it is <u><em>chemical</em></u><em> </em>potential energy, like in a battery, or a match. You get the energy out of a battery when you connect it to a motor or a light. You get the energy out of as match when you make the tip hot and it flares up.
This question is asking about <u><em>gravitational</em></u> potential energy. An object has stored energy just by being up high, like a bowling ball on a shelf. You get the energy out of it just by dropping it ... possibly enough to crack the floor !
The amount of this kind of potential energy is determined by the mass of the object, and how high up it is.
-- Getting the answers from other people doesn't help you a bit, until you understand them and can answer the question on your own.
The area of the sprinkles can be determined through the area of a circle that is pi * r^2 in which the given dimensions above are the radii, r. The second scenarios radius is only half of the original, that is 4 ft. In this case, we can compute the area of the second again. We calculate next the difference of two areas of circles.
It will have the strongest attraction for a conductor.
Answer:
Fracturing can emit seismic waves through the ground.
Explanation:
I believe the answer is seismic, I've studied this before.
Answer:
Distance(h1) = 12 m
Explanation:
Given
:
Height of cliff (h) = 4m
Time (t) = 1s
Intial velocity (u) = 0m/s
Computation:
Distance(h) = 1/2(g)(t)²
4 = 1/2(g)
g = 8m/s
²
Distance(h1) = 1/2(g)[(t1)²-(t)²]
Distance(h1) = 1/2(8)(3)
Distance(h1) = 12 m
