Answer:
As stated, the momentum of the system is conserved during the collision (even the kinetic energy is not - some energy is lost to heat, deformation, etc)
M1 V1 = M2 V2 expresses momentum conservation
150 kg-m/s = (40 + X) kg-m/s
X = 110 kg-m/s is the new momentum of the front car
More specifically,
M1 V1 + M2 V2 = M1 V1' + M2 V2'
If the moon moved closer to the earth, The gravitational force between them will increase.
This can be understood by Newton's law of universal gravitation. This is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
= G
If the moon moved closer to earth, the distance between them will be reduced, and as the force of gravitation is inversely proportional to the distance between the masses, the gravitation force increases.

Answer:Zero
Explanation:
Given
mass of ball 
If the ball is thrown upward then at maximum point velocity of ball is zero because ball is no longer able to move upward
Momentum(P) of a particle is given by



Therefore at the highest point momentum is zero .
Answer:
a small dense nucleus with positive charge and the nucleus is surrounding by orbiting electrons.
Explanation:
An experiment in which alpha particles were used to bombard thin sheets of gold foil led to the conclusion that an atom is composed mostly of a small dense nucleus with positive charge and the nucleus is surrounding by orbiting electrons.
