Equal to 50
law of reflection: angle of incidence equals angle of reflection
20 miles = 32186.9 meters
32186.9 / 340 = 94.667352
It will take 94.667 seconds to hear an explosion from 20 miles away.
Answer: Newton's second law of motion is F = ma or force is equal to the mass the reason this applies to Newton's third law is because When the game starts, both the sides are pulling the rope and neither side is moving. The force on the rope is the same on each side This is Newton's second law of motion which equates force as mass times acceleration.
Explanation:
Speed is the sum of distance divided by time
(speed = distance / time). So if you were to
decrease the distance traveled over the
same period of time, this will decrease the
speed. If either distance or time is increased
or decreased, the speed will do the same.
