Well you’d have a force due to gravity, the normal force which will be perpendicular to the sources (meaning you’ll have components to this vector), and you’d have the force of friction opposing the motion of the box. I’m also assuming there’s no air resistance. In this case you’d have three vector forces.

Answer:</h3>
[C] Velocity.
<h3>
Explanation:</h3>
<u>As we know that</u>,
<u>where, a = acceleration, v = final velocity, u = initial velocity and t = time taken to travel</u>.
Yes.
-- 'Acceleration' does NOT mean 'speeding up'.
It means ANY change in the speed OR direction of motion ...
speeding up, slowing down, or turning.
-- If an object is NOT moving in straight line at constant speed,
then its motion is accelerated.
-- In circular motion, or even just going around a curve,
the object is accelerating, because its direction is constantly
changing, even if its speed is constant.
Heya!!
For calculate wavelength, lets applicate formula:

<u>Δ Being Δ</u>
f = Frequency = 262 Hz
v = Velocity = 343 m/s
= Wavelenght = ?
⇒ Let's replace according the formula:

⇒ Resolving

Result:
The wavelength is <u>1,3 meters.</u>
Good Luck!!
