Tema [17]

Answer:

Voltage in the primary winding of the coil is 3.9 V

Explanation:

As we know by the principle of transformer we have

$\frac{V_s}{V_p} = \frac{N_s}{N_p}$

here we know that

$V_s = 25 volts$

$N_s = 3200$

$N_p = 500$

now we have

$\frac{25}{V_p} = \frac{3200}{500}$

$V_p = 3.9 Volts$

Why do we feel the force of gravity from the Earth but we don’t feel the force of gravity from the moon?

Zigmanuir [339]

Answer:

The gravitational force on the moon is less than on Earth because the strength of gravity is determined by an object's mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere. We just feel it in different ways depending on our state of motion.
