A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
Answer:
First Dot That is located on Earth.
Explanation:
Due to Earth's gravity being greater than the moon's on earth there is more gravitational force pulling down on the spacecraft.
Answer:
d = 
Explanation:
This comes from diffrection pattern equation used to locate fringe pattern, i will explain every variable in it here.
n = order of fringe = 0 1 2 3 .. and negative integars as well.
d is sacing between slits.
Theta = angle at which light-Ray is directed towards fringe.
It appears that the distance between consectice fringes would same as the distance between two slits 'd'.
therefore calculating that distance should give us the distance between two fringe patters.
Note we don't use transversal seperation distance here.
the answer is A it is so easy question
Answer:
Because sound doesn't move in vacuum (of space)
