Answer:

360 V

Explanation:

We can use the transformer equation:

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

where

V_p is the primary (input) voltage

N_p is the number of turns in the primary coil

V_s is the secondary (output) voltage

N_s is the number of turns in the secondary coil

In this problem,

V_p = 120 V\\N_p = 25\\N_s = 75

Substituting into the equation, we can find the output voltage:

V_s = N_s \frac{V_p}{N_p}=(75)\frac{120}{25}=360 V

The following force diagram represents Newton’s Third Law of Motion:
Julli [10]

Answer:

<u>FALSE.</u>

Explanation:

Newton's third law states that :

  • <em>Every action has equal and opposite reaction</em>
  • <em>That is , the magnitude is the same but the directions are opposite</em>
  • <em>The action reaction forces DONOT operate on the same body.</em>

For example ,

If a block is kept on the ground , the action force is the normal force acting on it due to the ground. <em>BUT , NOTE THAT : the reaction force isn't the gravitational force on the body ! It is the normal force acting on the ground due to the block !</em>

Thus,

we conclude that action and reaction forces donot act on the same body and therefore , this case has the <u>answer : FALSE </u>

Two equal charges with magnitude Q and Q experience a force of 12.3442 when held at a distance r. What is the force between two
Pepsi [2]

Answer:197.504 N

Explanation:

Given

Two Charges with magnitude Q experience a  force of 12.344 N

at distance r

and we know Electrostatic force is given

F=\frac{kq_1q_2}{r^2}

F=\frac{kQ\cdot Q}{r^2}

F=\frac{kQ^2}{r^2}

Now the magnitude of charge is 2Q and is at a distance of \frac{r}{2}

F'=\frac{k2Q\cdot 2Q}{\frac{r^2}{2^2}}

F'=16F

F'=197.504 N
