Answer:
it can be calculated by measuring the final distance away from a point, and then subtracting the initial distance
If a mass of a neutron is 1 the electron mass is 0.00054386734 and it's charge is negative. Hope this helps! ;)
Answer:
The torque is 0.31 Nm.
Explanation:
Electrical energy, E = 8400 J
time, t = 1 min
Angular speed, w = 2900 rpm = 303.53 rad/s
efficiency = 2/3 of input power
The toque is given by

Answer:

Explanation:
In an ideal transformer, the ratio of the voltages is proportional to the ratio of the number of turns of the windings. In this way:

In this case:

Therefore, using the previous equation and the data provided, let's solve for
:

Hence, the number of loops in the secondary is approximately 41667.
