force=mass × acceleration
mass=force ÷ acceleration
acceleration=force ÷ mass
F= (speed)/(wavelength)
Therefore, speed = Frequency x wavelength
V = 68m/s
Answer:
Explanation:
True
It is correct as the total rotational energy is the sum of transnational kinetic energy of each small piece of the object.
Consider a rigid body made of small particles each of mass dm have same angular velocity ω and the radius of the rotational path is r.
The velocity of each particle is v = r ω
So, the kinetic energy of each particle is
dK = 0.5 dm x v² = 0.5 x dm x r² x ω²
The total kinetic energy
K = 0.5 x I ω²
where, I is the moment of inertia
