<h3><u>Answer</u> :</h3>
◈ As per newton's second law of motion, Force is defined as the product of mass and acceleration
Mathematically,
Unit of mass : kg
Unit of acceleration : m/s²
Therefore,
Unit of force ➠ <u>kg m/s²</u>
SI unit : <u>N (newton)</u> or <u>kg m/s²</u>
Answer:
there it is fella u were right with ur answer
Answer:
s = 3.84 x 10⁸ m
Explanation:
The distance traveled by an object, while in uniform motion, is given by the following equation:
s = vt
where,
s = distance covered
v = speed
t = time interval
In this case:
s = distance between Moon and Earth = ?
v = speed of radio waves = 3 x 10⁸ m/s
t = time taken to travel = 1.28 s
Therefore,
s = (3 x 10⁸ m/s)(1.28 s)
<u>s = 3.84 x 10⁸ m</u>

Answer:
No. of turns in secondary coil are 5.
Transformer Type: STEP DOWN TRANSFORMER
Explanation:
The relationship of the no. of turns in transformer secondary and primary coils with their voltages is known as the turn ration. The formula for turns ratio is as follows:
Np/Ns = Vp/Vs
where,
Np = No. of turns in primary coil = 40
Ns = No. of turns in secondary coil = ?
Vp = Voltage supplied to primary coil = 120 V
Vs = Voltage output of secondary coil = 15 V
Therefore,
40/Ns = 120 V/15 V
Ns = 40/8
<u>Ns = 5</u>
TYPE OF TRANSFORMER:
Since, this transformer decreases the voltage value at the output. Hence it is a <u>STEP DOWN TRANSFORMER.</u>
