Yes it does (not to be mean its kinda stupid for you to ask)

Answer:
Explanation:
To calculate the time it took the car to hit the ground, we use the formula
speed = distance/time
80 m/s = 300 m/time
time = 300/80
time = 3.75 secs
It must have taken the car 3.75 seconds to hit the ground
To determine the horizontal distance of the car before hitting the ground, the same formula will also be used but with the time obtained above (since that was the time it took before hitting the ground)
speed = distance/time
80 = distance/3.75
distance = 3.75 x 80
distance = 300 meters
Answer:
The diameter of wire should be 
m
Explanation:
Given:
Current density 
Current 
A
From the formula of current density,
Where 
area of cylindrical wire = 
m
For finding the diameter of wire,
m
Therefore, the diameter of wire should be m
