Answer:
The seed as a fraction of the speed of light is
Solution:
As per the question:
Suppose, be the rate of an identical clock between two time intervals.
For a moving clock, moving with velocity 'v', at the clock tick of four-fifth:
t =
Now,
Using the relation of time dilation, from Einstein's relation:
Squaring both sides:
Answer:
110.25 J
Explanation:
We are given that
Mass,M=2.5 kg
Radius,R=0.5 m
Distance,d=4.5 m
Initial speed,u=0
We have to find the total kinetic energy
According to law of conservation of energy
Total kinetic energy=Potential energy=mgh
Where g=
Using the formula
Total kinetic energy=
Total kinetic energy
Answer:
t = 0.018 s
Explanation:
given,
nerve impulse in human body travel at a speed of = 100 m/s
height of the man = 1.80 m
time taken by the impulse to travel from foot to brain = ?
distance = speed × time
1.80 = 100 × t
t =
t = 0.018 s
hence, the time taken by the nerve to reach brain from toe is 0.018 s
