What is the velocity of an object with a mass of 4 kg and a momentum of 24 kg.m/s
Eva8 [605]

Answer:

6m/s

Explanation:

momentum = mass × change in velocity

∆p =m(v)

24 = 4(v)

V =>24/4 = 6m/s

Calculate the resistance of the 1000 W microwave oven that gets plugged into a 110 v outlet
alekssr [168]

The resistance of the 1000 W microwave oven that gets plugged into a 110 v outlet will be 10 ohms.

<h3>What is resistance?</h3>

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

P is the power= 1000 W

V is the voltage= 110 V

I is the current

R is the resistance

The resistance is found by the formula;

\rm P = \frac{V^2}{R} \\\\ \rm R = \frac{V^2}{P} \\\\  R = \frac{(100)^2}{10000} \\\\ R= 10\ ohm

Hence, the resistance value will be 10 ohms.

To learn more about the resistance, refer to the link;
