Answer:
0.20 A
Explanation:
The current in the wire is given by Ohm's law:
where
I is the current
V is the voltage
R is the resistance
In this problem,
V = 3.0 V is the voltage
is the resistance
Substituting into the formula,
Answer:
Its rotation will be 3.89x10⁴ rad/s.
Explanation:
We can find the rotation speed by conservation of the angular momentum:
(1)
The initial angular speed is:
The moment of inertia (I) of a sphere is:
(2)
Where m is 9 times the sun's mass and r is the sun's radius
By entering equation (2) into (1) we have:
Hence, its rotation will be 3.89x10⁴ rad/s.
