Answer:
Force = 10.244 Newtons
b) No of oscillations = 0.88
Explanation:
Since the block executes SHM we can write it's position as function of time as
ω is the natural frequency of the system
A is the amplitude of the system
Thus accleration of the block
Thus using the given values at t= 3.50 sec we can calculate the acceleration as
thus force can be calculated using newtons second law as
b)
Now no of oscillations can be obtained as
no of oscillations in 3.50 seconds = 3.50/3.976 = 0.88

Answer:
longer than
Explanation:
given,
time of nap = 10 min
speed of orbiting earth = 8000 m/s
c is the speed of light
using the equation of time dilation
now inserting all the values
t' = 10.001 s
on solving the above equation we will get a value greater than 10minutes.
hence, On earth time of nap measured will be longer than 10 min
Answer: 6.284N
Explanation:
Pressure is the ratio of force exerted to cross sectional area of the material.
Pressure = Force/Area
Pressure = 500,000Pa
Area = Πd²/4 where d is the diameter of the hole.
If d = 4mm = 0.004m
Area = Π×0.004²/4
Area = 1.26×10^-5m²
Force = Pressure×Area
Force = 500,000× 1.26×10^-5
F = 6.284N
The gum must be able to withstand 6.284N force
