The amount of heat will be equal to Lm.
Where L is the latent heat of fusion and m is mass of the ice.
Latent heat of ice = 80cal/g.
So the amount of heat required here will be 35× 80cal
= 2,800 cal.
4.285714268m/s/s is the answer
change in velocity divided by time equals acceleration
Answer:
Tangential speed = R * w where w is the angular speed
For a wheel v = .114 m * 6.53 / sec = .744 m/s
Note that this is the tangential speed - If the wheel were moving at speed V then as viewed from the ground you have
top V + v
bottom V - v
That is the wheel also has speed due to the speed of the axle (axis of rotation)
Answer:
Explanation:
From the question we are told that:
Accelerates at rate of
Acceleration time
Velocity time 1
Deceleration distance
Generally the Newton's equation for motion is mathematically given by
Answer
given,
length of rod (L)= 6 m
weight of the rod (W)= 10 N
rotates at = 240 rev/min
=
= 25.13 rad/s
a) Rotational inertia of the rod about axis of rotation
d is the distance from the center of gravity.
d = L/2
I = 27.55 kg.m²
rotational moment of inertia of the rod is equal to I = 27.55 kg.m²
b)angular momentum of rod
L = I ω
L =27.55 x 25.13
L = 692.36 Kg.m²/s
angular momentum of rod is equal to L = 692.36 Kg.m²/s
