Voltage = (current) x (resistance).
The current through the 60 ohms resistor is 0.10 A.
V = (0.10 A) x (60 ohms)
V = 6 volts
Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets

Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:
Now, for the average velocity of the girl we can use the following formula:
where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
KE = 1/2mv^2
m = 2000
v = 30m/s
1/2*2000*30^2=
1000*900 = 900,000kgm^2/s^2
