Answer:
A
Explanation:
I believe it is A because reflection is usually like a mirror or in water the other ones described are refraction or conversion. Hope this helps! :)
The term is frequency.
The frequency is the number of vibrations per unit of time or the number of waves that passes a point per unit of time.
Every crest (and every trough) represents a pass of the wave so you can count the number of crests in an intervavl of time to find the frequency as the number of crests divided by the time elapsed.
There is a horizontal abduction and horizontal adduction in the
transverse plane that is imaginary bisector that divides the body into two halves
upper or top and lower or bottom halves.
<span>Horizontal abduction involves the movement of the arm or thigh from
a medial or anterior position to a lateral position and in horizontal
adduction, the movement is reverse that is from lateral position to anterior
position.</span>
C African zone is correct
Answer:
(a) 
(b) 
(c) 44133.5 m
Explanation:
<u>Given:</u>
= initial speed of the rocket in the first stage = 0 m/s
= final speed of the rocket in the first stage
= final speed of the rocket in the second stage
= time interval of the first stage
= time interval of the second stage
= distance traveled by the rocket in the first stage
= distance traveled by the rocket in the second stage
= distance traveled by the rocket in whole time interval
Part (a):
Since the rocket travels at constant acceleration.
Hence, the expression of the rocket's speed at time 
.
Part (b):
In this part also, the rocket moves with a constant acceleration motion.
Hence, the expression of the rocket's speed in the time interval is 
.
Part (c):
For the constant acceleration of rocket, let us first calculate the distance traveled by the rocket in both the time intervals.
Similarly,
Hence, the rocket moves a total distance of 44133.5 m until the end of the second period of acceleration.
