1. Giga is the largest
2. Stem-and-leaf
This statement is true. The greater the mass is in an object, it is indeed the higher resistance to a change in movement the object will have. That only mean that the mass of an object and its resistance to change of movement is directly proportional.
The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s is 107 s
<h3>Data obtained from the question</h3>
The following data were obtained from the question given above:
- Initial velocity (u) = 11.1 Km/s
- Final velocity (v) = 11.7 Km/s
- Distance (s) = 1220 Km
- Time (t) =?
<h3>How to determine the time</h3>
The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s can be obtained as illustrated below:
s = (u + v)t / 2
Cross multiply
(u + v)t = 2s
Divide both sides by (u + v)
t = 2s / (u + v)t
t = (2 × 1220) / (11.1 + 11.7)
t = 2440 / 22.8
t = 107 s
Thus, the time taken for the spaceship to change its speed is 107 s

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>
