Answer: 65.25 J
Explanation:
Kinetic Energy K.E. = 1/2 * m * v^2 ; where m is the mass of the body and v is the velocity of the body ; K.E. = 1/2 * 0.145 * 30 * 30 = 65.25 Joules
Answer:
The correct answer is - do nothing.
Explanation:
If two same or identical objects, in this instance two glass rods, were rubbed together they neither attract nor repel each other as there is no transfer of electrons from one material to the other material as there is no difference in their charges.
Only two different objects are able to transfer electrons from one material to the other material if rubbed together, to produce the conditions for static electricity to be observed. Therefore there would be no charge on the glass rod so there would be no charge to balls to repel or attract.
Wavelength is measured in various units of distance (mm, cm, m, etc.). Frequency uses hertz, but that is not what the question is asking. Therefore, the answer is false.
Answer:
If the weight and forces are the same, it will result in a balance, i they are different, it will result in an overload in the lower force/mass object, reflecting it to the opposite direction with higher speed.

Answer:
Explanation:
No, the bungee jumper is not at equilibrium.
This can be explained when we consider a bungee jumper as a mass that is undergoing simple harmonic motion. At extreme points i.e. at the bottom, the velocity of the jumper is zero but not the acceleration because it is acting in the opposite direction that is why the jumper moves upward.
