Become more positive instead of negative
Answer:
In an elastic collision:
- There is no external net force acting. Thus, Momentum before and after collision is equal. Momentum remains conserved.
- Total energy always remains conserved as energy cannot be created nor destroyed. It can change from one form to another.
- There is no lost due to friction in elastic collision. So the kinetic energy is also conserved.
- Velocities may change after collision. If the masses are equal, the velocities interchange.
When one object is stationary:
Final velocity of object 1:
v₁ = (m₁ - m₂)u₁/(m₁ +m₂)
Final velocity of object 2:
v₂ = (2 m₁ u₁)/(m₁+m₂) =
- Objects do not stick together in elastic collision. They stick together in inelastic collision.
- One object may be stationary before the elastic collision.
Thus, conditions for an elastic collision:
- Energy is conserved.
- Velocities may change.
- Momentum is conserved.
- Kinetic energy is conserved.
- One object may be stationary before the elastic collision.
Answer:
gravity
Explanation:
the Forest of gravity causes objects to fall toward the center of the Earth.
This was given in our Chemistry subject so fortunately I hope this helps.
In mono culture farming, they produce a single specie of a livestock or plant in large number or quantity.
Yes it is very effective but producing a mass number of a single organism in a specific area will risk of endangering the existence of a certain and specific nutrient - this is because that large number of organism is basically eating the same thing.
This will actually lead to societal decision such as the founding of The Livestock conservancy and other environmental protection organization
