Answer: 8400 J
Explanation:
The formula referenced in the question is:
Where:
is the thermal energy
is the mass of the water sample
is the specific heat capacity of water
is the variation in temperature
Solving:
This is the thermal energy released
Answer:
c = 3.00E108 m/s = 3.00E5 km/s
t = S / v = 3.84E5 / 3.00E5 = 1.28 sec
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
as we know that angular acceleration of the wheel is given as
now the radius of the wheel is given as
R = 3.21 cm
so the tangential acceleration is given as
Part b)
frequency of the wheel at maximum speed is given as
now we know that
now radial acceleration is given as
Part c)
total angular displacement of the point on rim is given as
here we know that
now angular displacement will be
now the distance moved by the point on the rim is given as
