An electric heater works by passing a current of 112 amps through a coiled metal wire, causing it to become red hot. if the resistance of the wire is 0.95 ohms, what voltage must be applied to it?

Voltage, V = 106.4 volts

Explanation:

It is given that,

Current passing through coiled metal wire of electric heater, I = 112 amps

Resistance of the wire, R= 0.95 ohms

We have to find voltage applied to the electric heater. It can be calculated using Ohm's law. Mathematically, it can be written as :

V = 106.4 volts

Hence, this much amount of voltage must be applied to the electric heater.

chemical properties of thing

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.
