Answer:
this is due to difference in speeds of sound and light
Explanation:
light has a speed of 3×10^8 m/s and it is seen at once because it takes negligible time due to very high speed and short distance that is why as soon as lightning occurs we can see it . since thundering sound travels with speed of sound which is about 330 to 340 m/s in air hence it takes some time as described in question as 6 seconds
Answer:
2 ms^2
Explanation:
Given that the mass of the refrigerator is 200Kg
The net force acting on the refrigerator is 400N
The time takes is 4s
From Newtons's second law of motion;
F =ma
a = F/m
a = 400/200
a = 2 ms^2
This is a constant acceleration
