Answer:
C
Explanation:
Magnitude of any quantity is the measurable value of the quantity. While the direction of the given quantity is the specific pointing direction of position or the angle at which it move.
The magnitude of the vector described below? 13 m/s to the east will be 13 m/s
While the direction will be eastward.
Therefore, the magnitude is 13 m/s
The correct answer is option C
Answer:
5 hours
Explanation:
formula is 6 km per hour
if you have to travel 30 km, divide 30 by 6
30/6 = 5 hours
Answer:
As You know kinetic Energy is equal (mv^2)/2
You can increase it by increasing the mass(keeping the velocity)
Or You can add velocity
Explanation:
Answer:
(a) 108
(b) 110.500 kW
(c) 920.84 A
Solution:
As per the question:
Voltage at primary,
(rms voltage)
Voltage at secondary,
(rms voltage)
Current in the secondary,
Now,
(a) The ratio of secondary to primary turns is given by the relation:

where
= No. of turns in primary
= No. of turns in secondary
≈ 108
(b) The power supplied to the line is given by:
Power, P = 
(c) The current rating that the fuse should have is given by:
