Some metal conductor has a resistance of 12ohm. When plugged into a circuit, the amount of heat 144J is released in 12s. What is the voltage at the ends of the conductors?

The voltage at the end of the conductors is 12V

Explanation:

Given:

Resistance, R = 12Ω

Heat released, H = 144J

Time, t = 12s

Voltage, V = ?

According to joule's law:

H = I²RT

where,

I is the current

T is the time

R is the resistance

The above formula can also be written as:

where,

V is the voltage

On substituting the value in the formula we get:

Therefore, the voltage at the end of the conductors is 12V

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
