Answer:
Longitudinal waves travels faster through solids than it does through gases
Explanation:
As we know that longitudinal waves travels through all types of mediums and the speed of longitudinal waves is given as
here we know that
E = elasticity of the medium
= density of the medium
now here we know that elasticity of solids is much more than the elasticity of gases
So the speed of longitudinal waves in solids is more than the speed of waves in gases

Answer:
The horizontal component of the velocity is 188 m/s
The vertical component of the velocity is 50 m/s.

Hi there!
Please, see the figure for a graphic description of the problem. Notice that the x-component of the vector velocity (vx), the y-component (vy) and the vector velocity form a right triangle. Then, we can use trigonometry to obtain the magnitude of vx and vy:
We can find vx using the following trigonometric rule of a right triangle:
cos α = adjacent / hypotenuse
cos 15° = vx / 195 m/s
195 m/s · cos 15° = vx
vx = 188 m/s
The horizontal component of the velocity is 188 m/s
To calculate the y-component we will use the following trigonometric rule:
sin α = opposite / hypotenuse
sin 15° = vy / 195 m/s
195 m/s · sin 15° = vy
vy = 50 m/s
The vertical component of the velocity is 50 m/s.
