Answer:
c) both containers slide off the turntable at the same turntable speed.
Explanation:
The greater the mass of the cylinder, the greater the centrifugal force acting on it. That makes up for the greater force needed to move the heavier cylinder.
Answer:
Explanation:
From the information given,
V = 4 volts
A = 2 amps
a)
In the first instance, one light on the sting goes out and the whole string of lights no longer turns on. This means that the circuit is a series circuit.
b) Total voltage = 4 x 100 = 400 V
The current passing through each bulb is the same. Thus
Total Current = 2 Amps
Recall, V = IR
R = V/I
Thus,
Resistance = 400/2
Resistance = 200 ohms
c) In this case, one light goes out on the string all other lights still turn on. This means that the circuit is a parallel circuit
d)
The voltage is the same
Total voltage = 4 volts
Total current = 2 x 100 = 200 amps
Total resistance = 4/200
Total resistance = 0.02 ohms
