Answer:B.
Both increase as the mass and velocity increase.
They help scientists explain concepts that are difficult to observe.
Answer:
Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
the unit for volt is v
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
50(6)=300.
The ball traveled 300 meters in 50 seconds.
