Answer:
This is because The glass rod of the electroscope is an insulator therefore only charge transferred to the ball is at the point of contact on the rod. Thus, When the charge rod is dragged across the top of the electroscope, by the experienced teacher the more charge is transferred to electroscope thereby producing a greater effect
Well usually when you go on a diet, you don't really want gain weight, when you lose 20 pounds on a diet to 20 pounds that you lost got used as energy for your body, if you eat healthy then you can expect to see weight loss.
As this mechanical energy is associated with height, it would be "Potential Energy" in particular.
U = mgh
U = F.h
U = 1.5 * 4
U = 6 Joules
So, 6 J of energy is lost before it hits the ground.
Hope this helps!
The acceleration of gravity on the surface of the Moon is about 1.62 m/s^2.
Answer:
<u>Option-(D):</u>Thermal energy unchanged, temperature decreased.
Explanation:
<u>Thermal energy and Temperature,T:</u>
Thermal energy of the system is remained unchanged while the temperature,T of the objects present inside the system is more associated with the objects fundamental properties which each matter shows or exhibits in nature.
While the thermal energy is the flow or exchange of thermal or heat energy between the different objects in interaction to each other.
