A
longitudinal wave is a mechanical wave that causes the medium to vibrate
parallel to the direction of the wave. Its wave’s forces travel through
multiple rarefactions and compressions where compression is the closest
distance in the longitudinal wave and rarefaction is the farthest distance
apart in the said wave.
Answer:
b,c
Explanation:
Velocity refers to the rate of change of position with respect to time and acceleration refers to the rate of change of velocity with respect to time. Both velocity and acceleration are vector quantities
While the line of children is rotating, <u>the player at the front of the line has the smallest linear velocity and all the children have the same angular acceleration.</u>
The answer of this question is B. 22x + 20
Answer: E.
Explanation: because the book is on the table, its not really moving in any direction.
Answer:
The take-off speed is 41.48 
Explanation:
Given :
Range 
m
Projectile angle 
13°
From the formula of range,
Find the velocity from above equation,
( ∵ 
)
Therefore, the take-off speed is 41.48
