Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. Which of these illustrates Ne wton’s Third Law? A: Two students of similar mass run into each other. They bounce off each other when they collide.
B: Two students of similar mass run side by side into a wall and punch holes of equal size before emerging on the other side.
C: Two students of similar mass run in opposite directions, but one accelerates at twice the rate of the other.
D: Two students of similar mass run at the same speed in opposite directions on a track. They will collide with 400 Newtons of force in 400 meters.
1 answer:
Answer:
A
Explanation:
An equal and opposite reaction happens when they run into eachother and bounce off. What makes it equal is when they have the same amount of force applied when they collided.

d) What is the force if we doubled both the masses AND we doubled the distance
(100, 108) Due to 1.2x90=108 100, 108
south = -(north)
Displacement = (4 km north) + (2 km south) + (5 km north) + (5 km south)
Displacement = (4 km north) - (2 km north) + (5 km north) - (5 km north)
Displacement = (4 - 2 + 5 - 5) km north
<u>Displacement = 2 km north </u>
Answer:
434.97041
Explanation:
Answer:
Explanation:
E₀ = 229.1 V/m
E = E₀ / √2 = 229.1 / 1.414 = 162 V/m
B = E / c ( c is velocity of em waves )
= 162 / (3 x 10⁸) = 54 x 10⁻⁸ T
rate of energy flow = ( E x B ) / μ₀
= 162 x 54 x 10⁻⁸ / 4π x 10⁻⁷
= 69.65 W per m².
