Answer:
Explanation:
Formula to calculate the distance between two points and is,
d =
Therefore, length of CD having coordinates C(3,1) and D(3, 3),
CD =
= 2 units
Formula to find the midpoint of CD is,
M =
=
= (3, 2)
Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.
The temperature of the CMB is cooler, not hotter, than at the time of the big bang.

Thermal energy is converted to radiative energy via molecular collisions and released as photons.
2.5m/s^2
Step one:
given
distance = 20meters
time = 2 seconds
initial velocity u= 0m/s
let us solve for the final velocity
velocity = distance/time
velocity= 20/2
velocity= 10m/s
divide both sides by 40
p=mv
?=15kg * 3m/s
45p
