Stressing an equilibrium simply means that the physical properties in which already exists are balanced. Stress can be applied by either changing the pressure or the volume or temperature.
Answer:
255N
Explanation:
Given parameters:
Mass of barrel = 75kg
Acceleration = 3.4m/s²
Unknown:
Force exerted = ?
Solution:
Force is the product of mass and acceleration according to Newton's second law of motion.
Force = mass x acceleration
Now insert given parameters and solve,
Force = 75 x 3.4 = 255N
Answer:
time taken = 6 secs
Explanation:
Power (P) = Force(F) * displacement(d)/ TIME (t)
75= 225 * 2.0/t
t= 225*2/75
t= 6 sec
Answer:
The ring has a larger moment of inertia.
Explanation:
Given that the mass of disc=61 kg
Let the radius of the disc is R
The moment of inertia of the disc having mass m, about the axis passing through the center of the disc,

Mass of hoop = 36 kg
As the radius of disc and hoop is the same, so the radius of the hoop is R.
The moment of inertia of the ring (hoop) having mass m, about the axis passing through the center of the disc,

Hence, the ring has a larger moment of inertia.
