Answer: The ball would have the most kinetic energy at the lowest point and the most potential energy at the top of the hill
Explanation:
Since you didnt add the picture I cant tell which multiple choice answer it would be, but I hope this helps :)
Answer: 0.8
Explanation:
The efficiency is defined as the ratio of total imput energy that is actually utilized to the end of the device.
So if we have a total transfer of 1500j of energy, and 1200j are used to heat the thing inside the kettle, 300j are not used to the actual function of the kettle.
So the efficiency is n = 1200j/1500j = 0.8
This means that a 80% of the energy imput is actually used to heat the kettle.
Hey there :)
The increasing energy and frequency order is:
Radio waves, Microwaves, Infrared Rays, Ultraviolet Rays, X-Rays and Gamma Rays.
This is as well the decreasing wavelength order
Answer:
Explanation:
1. The net force acting on an object is the combination of all of the individual forces acting on it.
2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
