Lumbar nerves transmit signals that allow us to walk. They are a pivotal part of the human body, and without them we would be immobile. Hope this helps.
Given parameters:
Speed of car = 50m/s
Time of travel = 5minutes (300s)
Unknown;
Distance of travel = ?
To solve this problem, we need to understand how speed relates with distance and time.
Speed is a physical quantity. It is the distance traveled divided by time taken.
Speed = 
So,
Distance = speed x time
Input the parameters and solve for the distance;
Distance = 50m/s x 300s
Distance = 15000m
The distance covered during this time interval and speed is 15000m
It takes Δt time to travel the Em wave which is on top of the microwave to bottom of the microwave.
Δt = h/c
P = E / Δt = cE/h
P = 3× 10⁸ ₓ 0.5 10⁻⁶ / 0.25
600w.
