A disk drive plugged into a 120V outlet operates on a voltage of 12V . The transformer that powers the disk drive has 125 turns

Serga [27]

Answer:

(A-) Number of turns in secondary coil will be<u> less than 125.</u>

(B-) EXPLAIN- The voltage is to be lowered.<u> The voltage will be reduced from 120 to 9 volts.</u> As a result, a<u> step down transformer </u>will be used, indicating that the secondary coil's number of turns would be less than 125.

(C-)<u> The number of turns on the secondary coil is 12.5</u>

<u></u>

Explanation:

STEP DOWN TRANSFORMER - A step-down transformer transforms high voltage (HV) and low current from the transformer's primary side to low voltage (LV) and high current on the secondary side. A phase down transformer is the opposite of this.

In electrical networks and transmission lines, a step-down transformer can be used in a number of ways.

<u>Step down transformer formula-</u>

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

We are given with the -

Primary voltage $V_p$ = 120V

Secondary voltage $Vs=12V$

Number of primary turns $N_p=125$

<u>To calculate the number of turns on the secondary coil -</u>

Since , the transformer ratio is given as -

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

So, the number of turns on the secondary coil is - $N_s=N_p\times\frac{V_p}{V_s}$

Putting , the given values -:

$125\times\frac{12}{120}$

= 12.5

<u>Therefore , the number of turns on secondary coil is 12.5 .</u>

science numerical problem .Hari drag a load a of 60 kg along a distance of 12 m . what amount of work does he do? as 0 mention t

Komok [63]

We don't know, and we don't have enough information to calculate it.

The weight of the 60kg load is (m g) = 588 Newtons.

IF Hari wanted to<em> lift </em>the load 12m <em>straight up</em>, he would have to do

(Force x distance) = (588 N) x (12 m) = 7,056 Joules of work.

But to drag it, he has to provide enough force to balance out the force of friction, and we don't know how much that is. It depends on the weight of the load, the shape of the load, the smoothness of the part of the load that sits on the ground, and the smoothness of the ground. But the only thing we know is the weight of the load.

What happens to momentum when two objects collide

Lostsunrise [7]

Answer:

The sum of momenta of each object before and after collision is equal . Thus when they collide , their momentum will change but its sum will be sane as the sum of the momentum before collision
