Answer:
39.2 N
Explanation:
1kg at the earth's surface has a force of 9.8 N acting on it.
(4 kg) (9.8N) = 39.2 N
It rises up the the surface when the surrounding rock is less dense
Answer:
f=15.5 Hz
Explanation:
Let's determine the internal resistance:
ρ = 1.68*10^-8 Ω m
Ω
Since the bulb is rated at 12.0 V and 25.0 W,
Current
Therefore, voltage drop inside generator =
Actual EMF required is
Note that this is an RMS value.
The peak voltage is
For a generator, by Faraday's Law,
*ω
ω
f=ω/(2π)=
f=144.5 rad/s/(2π)
f=23.001 Hz
