What happens to the force of gravitational pull if we tripled the distance and one of the masses is doubled

2 answers:

5 0

Triple the distance ... The force drops to 1/9 of the original force.

Double one mass ... The original force doubles.

Do both ... The original force becomes 2/9 as strong, = about 22.2% of what it was originally.

This depends on the original mass of the object having its mass doubled and the the original distance before the distance was tripled.

how much voltage is in the primary coil if there are 3200 winding in the secondary coil 500 winding in the primary and 25v in th

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

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

$V_p = 3.9 Volts$

Coulomb's law is expressed mathematically as

nataly862011 [7]

Force between two charges =

( 1/4πε₀ ) · (Charge #1) · (Charge #2) / (Distance between them)²

in the direction away from each other.

In other words, if the force is positive, the charges are repelling.
If the force is negative, the charges are attracting.
