Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.

Ksivusya [100]

Answer : Radius of Earth is 6,340 Km.

Explanation

It is given that,

Tangential velocity of Earth at the equator, v = 465 m/s

Centripetal acceleration at the equation is, a_c=3.41\times 10^{-2}\ m/s^2

We know that the relation between centripetal acceleration and tangential velocity is :

a_c=\dfrac{v^2}{r}..........(1)

Where,

v is tangential velocity

r is the radius

Putting all values in equation (1)

3.41\times 10^{-2}\ m/s^2=\dfrac{(465 m/s)^2}{r}

r=6340909\ m

or

r=6,340\ Km

The Earth's radius is 6,340 Km. Hence, this is the required solution.

Leni [432]

Answer:

Part a)

I = 17.4 \times 10^{-3} kg m^2

Part b)

I = 14.9 \times 10^{-3} kg m^2

Explanation:

Part a)

Moment of inertia of the core of the ball

I_1 = \frac{2}{5}m_1r_1^2

I_1 = \frac{2}{5}(1.6)((\frac{0.196}{2})^2)

I_1 = 6.14 \times 10^{-3} kg m^2

now the moment of inertia for thin shell

I_2 = \frac{2}{3} m_2r_2^2

I_2 = \frac{2}{3}(1.6)((\frac{0.206}{2})^2)

I_2 = 11.3 \times 10^{-3} kg m^2

now total inertia of the ball is given as

I = I_1 + I_2

I = 17.4 \times 10^{-3} kg m^2

Part b)

Moment of inertia of uniform ball of mass 3.2 kg

I = \frac{2}{5} mr^2

I = \frac{2}{5}(3.2)((\frac{0.216}{2})^2)

I = 14.9 \times 10^{-3} kg m^2
