Answer:
The average speed is 1 m/s
The average velocity is 0
Explanation:
Given;
length of the pool, L = 50 m
time taken for the motion, t = 100 s
The total distance = 50 m + 50 m
The total distance = 100 m
The average speed = total distance / total time
= 100 / 100
= 1 m/s
The average velocity = change in displacement / change in time
change in displacement = 50 m - 50 m = 0
The average velocity = 0 / 100
The average velocity = 0
Answer:
transverse wave. it goes up and down :)
Answer:
1270 segundos
Explanation:
Dada,
Velocidad ( v ) = 3810 m/s
Distancia ( s ) = 3 m
Encontrar : -
Tiempo que tarda el sonido en viajar ( t ) = ?
Fórmula : -
s = d / t
t = d / s
= 3810 / 3
t = 1270 segundos
Answer:
There must be a lot of dark matter that can be felt but not seen
A force is required, because nothing would happen if there was no energy to start it.
