Answer:
They can travel through vacuum.
Explanation:
Sound waves are vibration that travel through particles such as solid, liquids, and gas.
A media query determines the capability of the mobile device, such as screen resolution, and directs browsers to CSS.
<h3>What is the usefulness of a media query d?</h3>
Media queries can be expressed as key part of responsive web design because they give room for a programmer to be able to create different layouts depending on the size of the viewport.
These queries is also essential in detecting other things as regards the the environment that the site is running on, like may be the user is is operating with touchscreen or may be he is using mouse.
Hence, A media query determines the capability of the mobile device, such as screen resolution, and directs browsers to CSS.

For this we will use kinematic equations.
We need the time of flight to compute the range.
With the given information, the most useful formula is:
Δy=v0yt−g2t2
Because our equation is taking only vertical motion into account,
v0y=30sin(45)
Because we are looking for the range of the object,
Δy=0
This leaves us with only one unknown: t
0=30sin(45)t−g2t2
g2t2=30sin(45)t
g2t=30sin(45)
t=60gsin(45)
For horizontal distance, the formula we need is:
Δx=v0xt
Because we are taking into account the horizontal range,
v0x=30cos(45)
In substituting our derived values into the equation we can see that:
Δx=30cos(45)∗60gsin(45)
Range=30cos(45)∗60gsin(45)
It'll go straight. You need to cut the throttle to idle, then make a hard right. The PWC will have no control at that point.
