Answer: Temperature is also a condition that affects the speed of sound. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second.
Explanation: so basically, yes!
Answer:
5m
Explanation:
Using Pythagoras theorem,
a^2+ b^2=c^2
3^2+4^2=c^2
25=c^2
√(25)=c
5m=c
Absolute zero is from the Kelvin scale.
Answer:
A force
Explanation:
A push or a pull is an example of a force and can cause an object to speed up, slow down, etc.. Newton's laws tell us that 1- an object will not change its motion unless a force acts on it 2- the force on an object is equal to its mass times its acceleration. 3- The third law states that for every action (force) in nature there is an equal and opposite reaction.. However, forces like gravity and friction can resist movement.
Answer:
Because the rope is stopping the force of gravity from acceleration it.
