Answer:

Any medium solid, liquid or gas is required for sound waves to travel.

Explanation:

A sound wave requires a medium to travel. Sound waves are mechanical waves that is why these waves require a medium to travel. Sound waves can travel through solids, liquids, and gases.

In solids, the particles of the medium are closely packed together as compared to liquids and gases. In liquids, particles are less tightly packed and almost negligible in gases.

Therefore sound waves produce vibration in the dense or solid medium. Denser the medium faster the sound waves travel. However sound waves can not travel through empty space.

sasho [114]

Answer:

Velocity will be $v=1.291\times 10^8m/sec$

Explanation:

We have given magnetic field B = 0.00005 T

Mass m = 238 U

We know that $1u=1.66\times 10^{-27}kg$

So 238 U $=238\times 1.66\times 10^{-27}=395.08\times 10^{-27}kg$

Radius $=R+1.44=6378+1.44=6379.44KM$

We know that magnetic force is given by

$F=qvB$ which is equal to the centripetal force

So $qvB=\frac{mv^2}{r}$

$1.6\times 10^{-19}\times v\times 0.00005=\frac{395.08\times 10^{-27}v^2}{6379.44}$

$v=1.291\times 10^8m/sec$
