Suppose an earthquake occurs on an imaginary planet. Scientists on the other side of the planet detect primary waves but not sec
MrMuchimi

Answer:

a. part of the planet's interior is liquid

Explanation:

Seismic waves are slowed down in a liquid medium. On earth, molten areas reduces the speed of P waves and completely stops S waves which have shearing motion that can only be transmitted through a solid

The motion has the highest speed in materials, allowing it to be detected first on seismograms. The P wave is has a smaller wavelength and a higher frequency than the surface ans the S waves.

A 4.2-m-diameter merry-go-round is rotating freely with an angular velocity of 0.79 rad/s . Its total moment of inertia is 1790
Nezavi [6.7K]

Answer:

w_2=0.467rad/s

Explanation:

Four people standing on the ground each of mass and usually this questions have to find the final angular velocity

m_t=4*70kg=280kg

The radius r=4.2/2=2.1m

Angular velocity  w_1=0.79rad/s

The moment of inertia total is I_t=1790 kg/m^2

Momento if inertia

I_1=m_t*r^2

I_1=280kg*(2.1m)^2=1234.8kg*m^2

Angular momentum

I_1*w_1=I_t*w_2

Solve to w2

w_2=\frac{I_1*w_1}{I_t}

w_2=\frac{1790kg*m^2*0.79rad/s}{3024.8kg*m^2}

w_2=0.467rad/s
