Answer:
The resistance of the motor is 8.91 ohms.
Explanation:
Given that,
Voltage of the socket, V = 120 V
Current, I = 2.4 A
Back emf generated by the electric motor is, E = 98.6 V
We need to find the coil resistance of the motor. The new emf on the vacuum cleaner is


The resistance of the motor is given by :

So, the resistance of the motor is 8.91 ohms. Hence, this is the required solution.
gold density = 38.6 *10^-3 / 2 *10^-6 = 19300 Kg/m3
Iron density = 46.8 *10^-3 / 6 *10^-6 = 7800 Kg/m3
water mass = density*volume = 1 * 10 = 10 grams = 0.01 Kg
pushing on something that pushes back = action and reaction.
Gravity is non contact. Action at a distance. Hence stones wil fall if dropped.
750 divide 50 which is 15n
or it is 750 times 50 which is 37500n
