Answer:
The store energy in the inductor is 0.088 J
Explanation:
Given that,
Inductor = 100 mH
Resistance = 6.0 Ω
Voltage = 12 V
Internal resistance = 3.0 Ω
We need to calculate the current
Using ohm's law


Put the value into the formula


We need to calculate the store energy in the inductor



Hence, The store energy in the inductor is 0.088 J
The new volume = 3 x 52.6 that’s because as the pressure decreases by 1/3 the volume increases x3
Answer:
The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth.
The force that opposes motion to moving parts is F<span>riction</span><span>
