Nine trillion four hundred twenty-four billion eight hundred million
Answer:
The correct option is (b) i.e. 0.03 m.
Explanation:
We have,
Speed of a wave is 0.09 m/s and the frequency of a wave is 3 Hz.
It is required to find the wavelength of a wave.
The speed of a wave in terms of wavelength and frequency is given by :
So, the wavelength of a wave is 0.03 m.

To solve the problem, it will be necessary to define the rotational and translational kinetic energy in order to determine the relationship between the two. Rotational energy is defined as,
Here,
I = Moment of Inertia
= Angular velocity
Now the translational energy will be,
Here,
m = Mass
v = Velocity
Therefore the relation between them will be,
Applying the moment of inertia of a sphere we have,
Therefore the ratio will be 0.01077
Answer:
0.6375 cm
Explanation:
coefficient of linear expansion of copper, α =
Lo = 25 m
Δ T = 25 degree C
According to the formula of thermal expansion which is linear in nature is given by
Where, ΔL be the change in length
=0.6375 cm
