An electric heater carries a current of 13.5 A when operating at a voltage of 120V . What is the resistance of the heater?
Aloiza [94]

An electric heater that carries a current of 13.5 A when operating at a voltage of 120V , will have  the resistance of the heater as 8.89 ohm.

<h3>What is Ohm's law?</h3>

Ohm's law  can be described as the law in physics that   focus on how voltage or potential difference between two points is directly proportional to the current or electricity that is moving in the direction of the resistance.

An this is also  directly proportional to the resistance of the circuit, hence it can be calculated using the Ohm's law is V=IR.

from V=IR

R=V/I

= 120/13.55

=8.89 ohm.

Therefore,  electric heater that carries a current of 13.5 A when operating at a voltage of 120V , will have  the resistance of the heater as 8.89 ohm.

A paper airplane with mass 0.1 kg is flying 1.5 m above the ground with a speed of 2 m/s. What is the total mechanical energy of
Wewaii [24]
Total mechanical energy = kinetic energy + potential energy
E = KE + PE
E = ½mv² + mgh
E = ½(0.1 kg)(2 m/s)² + (0.1 kg)(9.8 m/s²)(1.5 m)
E = 0.2 J + 1.47 J
E = 1.67 J
