According to Boyle’s law, For a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional.
Therefore,
Given ,
and
.
Thus,
Two events are observed in a frame of reference S to occur at the same space point, with the second event occurring after a time
of 1.70 s . In a second frame S' moving relative to S, the second event is observed to occur after a time of 2.25 s . What is the difference between the positions of the two events as measured in S'?

as there is no acceleration in x direction therefore horizontal velocity is same
Answer:
upward force acting = 261.6 N
Explanation:
given,
mass of gibbon = 9.4 kg
arm length = 0.6 m
speed of the swing
net force must provide
force of gravity = - mg
=
=
=9 x 29.067
= 261.6 N
upward force acting = 261.6 N
