<u>Force = kgm/s² ⟶ Newton</u>
<h2><u>
Explanation:</u></h2>
<u></u>
According to the formula we've learnt,
- Force = mass × acceleration.
To find force in terms of base units, we must first identify the base SI units of mass & acceleration.
- Base SI unit of mass = kg (kilogram)
- Base SI unit of acceleration = m/s² (meter per second squared)
So, the base unit of force is,
- Force = mass × acceleration.
- <u>Force = kgm/s² ⟶ Newton</u>

Hey there!
The answer would be B. The sound moves from air to water.
Sound travels through different mediums. It goes fastest in solids, a little slower in liquids, and slowest in air. Sound is a very fast wave, but remember that mediums can differ that. In a vacuum space, there is no sound at all. (ex. outer space)
Hope this helps !

Answer: D) 30</h3>
Angle of incidence always equals angle of reflection. Think of a tennis ball being hit into a wall. The ball will bounce off at the same angle that it approached with. The angles mentioned are formed through the line called the "normal", which is the line perpendicular to the surface.
