The correct answer is
<span>C. The current in the battery and in each resistor is the same.
In fact, when resistors are connected in series, the current flowing through them is the same in each resistor. This is also equal to the current flowing in the circuit, so it is the same as the current flowing through the battery.</span>
True. The mass of an electron is about 1/2000 amu whereas the mass of a proton is 1 amu.
Answer:
Correct answer: Third statement P = 4900 W
Explanation:
Given:
m = 500 kg the mass of the elevator
h = 10 m reached height after t = 10 seconds
P = ? power of the motor
The formula for the calculating power of the motor is:
P = W / t
since work is a measure of change in this case of potential energy then it is:
W = ΔEp = Ep - 0 = Ep
In this case we must take g = 9.81 m/s²
Ep = m g h = 500 · 9.81 · 10 = 49,050 W ≈ 49,000 W
Ep ≈ 49,000 W
P = Ep / t = 49,000 / 10 = 4,900 W
P =4,900 W
God is with you!!!
Answer:
ke = 1/2mv^2
= 1/2 * 1200 * 22^2
= 600 * 484
= 290400 J
Hope it helped u,
pls mark this as brainliest
