The forces that do non-zero work on the block are gravity and normal reaction force
Explanation:
The physical description would be soft due to the lava cooling the rock.
Answer:
I think it's 0 N 3rd choice
The mass of the astronaut is still 65 kilograms. Mass is constant or doesn't change no matter where you are.
The relationship between inductance and frequency can be clearly described using the following equation of inductive reactance:
Xl = 2*pi*f*L ; simplifying:
L = Xl / 2*pi*f
Therefore, as what we saw, inductance and frequency are inversely proportional. To add up, when inductance increases the frequency would decrease.
