Explanation:
A. 1.35 is the number in between 1.2 and 1.5.
Answer:
20 m/second squared
Explanation:
Initial velocity of the car (u) = 0 m/s
Final Velocity of the car (v) = 120 m/s
Time (t) = 6 seconds
The intensity of an electromagnetic wave increases with the field strength.
Answer:
The train is moving with a speed of 57.6 m/s.
Explanation:
Given that,
Distance of observer from the road, d = 40 m (due south)
Velocity of the train, v = 60 m/s (due east)
So,
t is time
Net displacement is given by :
Differentiating above equation wrt t as :
Put t = 4 s
So, the train is moving with a speed of 57.6 m/s.
