The speed of an object that travels 400 km in 5 hours, would be calculated simply by taking the distance of 400 and dividing it by the number of hours 5.
400 km/5 hours = 80km/hr.
The speed is 80 km/hr.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
The wording of this can be bothersome. I think you should be using
E = F * d
E = 68 J
d = 12 m
F = ???
68J = F * 12 m
68J/12 m = F
5.67 N

Answer:Light (electromagnetic) energy does not require a medium through which to travel.
Explanation:
Electromagnetic waves doesnt need to medium for travell
Ex ; Ultra violet rays , X rays
