the sun was stationary in the center of the universe and the earth revolved around it....
Young's double slit experiment(YDSE) can be used for any kind of waves such as electromagnetic waves, sound waves, water waves, gravity waves. YDSE is based on interference. In this experiment, we make two waves interfere in order to obtain bright and dark fringes on the screen(in case of light).
You can carry this out with water, would be great if you try this at pond or water reservoir in order to see perfect ripples.
Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
Answer:
The direction of the momentum of the large ball after the collision with respect to east is 146.58°.
Explanation:
Given that,
Mass of large ball = 3.0 kg
Mass of steel ball = 1.0 kg
Velocity = 3.0 kg
After collision,
Velocity = 2.0 m/s
Using conservation of momentum




The direction of the momentum



The direction of the momentum with respect to east

Hence, The direction of the momentum of the large ball after the collision with respect to east is 146.58°.
