B. Some of the ball’s energy is transformed to thermal energy.
Hope this helps you!
Friction produces heat hope this helps
Isn’t it a light box , mirror and / or angle measurer?
These actions are an example of feedback.
Given that the room has reached the desired temperature, there is no more need for it to be heated, at least until the temperature drops a bit. This is why the thermostat sends feedback about this situation to the heater, which immediately switches off until it is needed again.
Answer:

Explanation:
= Maximum charge stored by capacitor = 6 μC = 6 x 10⁻⁶ C
= time taken for charge on the capacitor to become zero = 2 ms = 2 x 10⁻³ s
Time period is given as



Angular frequency is given as


=785 rad/s
Charge at any time is given as

Taking derivative both side relative to "t"


Amplitude of the current is given as
