Explanation:
As we know that relation between force, mass and acceleration is as follows.
F = ma
where, F = force
m = mass
a = acceleration
So, it is given that force is 3000 N and mass is 200 kg. Hence, calculate the acceleration as follows.
F = ma
3000 N =
a =
=
Thus, we can conclude that acceleration of the given object is .
Answer:
8.66 nano seconds
Explanation:
speed of k mesons ( v ) = c m/s
Distance between counters ( d ) = 9.00 m
number of countable electrical pulses = 1000 counts in first counter and 250 in second counter
time of travel = d / v = 18 / secs
Next write the decay of particles in lab frame
finally calculate the half life of Meson in its own frame
( t 1/2) of meson in its own frame = 8.66 n-secs
attached below is a detailed solution
