A soldier fires a gun and another boy at a distance of 1020 m hears the sound of firing the gun 33 seconds after seeing its smoke. Find the speed of sound. .

Explanation:

The speed of the sound can be found using the following equation:

Where:

v: is the speed

d: is the distance = 1020 m

t: is the time = 33 s

Therefore, the speed of the sound is 30.91 m/s.

I hope it helps you!

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
