Answer:
In a tennis match, the racket exerts the action force on the ball and, as the ball hits it, it exerts an equal and opposite reaction force on the racket. The rocket launches because it pushes on the gas coming out the back end for the action force, while the gas pushes the rocket upward with a reaction force.
Answer:
Explanation:
l = 200 m
i = 5 A west
B = 6 micro Tesla direction 30 degree north of east
angle between length vector and the magnetic field vector = 180 - 30 = 150 degree
Write the length and the magnetic field in the vector form
Thus, the magnitude of force is 3 x 10^-3 newton and it is directed towards negative z axis direction.
I am almost sure it it (c)
Yes
Explanation:
This chemical equation:
is balanced, because the number of atoms of each element is the same on the reactant side and on the product side. In fact:
- Mg: one atom on the left, one on the right
- I: 2 atoms on the left, and 2 on the right
- Br: 2 atoms on the left, and 2 on the right
So, the reaction is balanced.
some form of destructive interference. if phase is 180 degrees out, destructive = darkfringe or quiet in sound
