ΔPE = mgh₂ - mgh₁= mg(h₂- h₁) = mgΔh
Answer:
3260.33 J
Explanation:
= number of rods = 5
= length of each rod = 0.715 m
= mass of rod = 2.51 kg
= total moment of inertia
Total moment of inertia is given as
= 2.14 kgm²
= angular speed = 527 rpm = 55.2 rad/s
Rotational kinetic energy is given as
E = (0.5) ( )²
E = (0.5) (2.14) (55.2)²
E = 3260.33 J
Answer:
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container
Explanation:
Bro again the same type of sum..
well
it takes 3 second to hit the ground
the height will be
h = 5*3*3
h = 45m
horizontal distance would be
velocity*time
10*3 ,= 30m/s
