Answer:
A. Methane gas from agriculture Pollution.
Explanation:
Methane gas is a great contributor to the global warming. It effects the green house of the earth and ozone layer is deteriorated. Grand father mountains are located in the North Carolina where the Methane gas pollution destroys the trees.
Answer:
A.) Core
Explanation:
Core definition: a central and often foundational part usually distinct from the enveloping part by a difference in nature.
6 m/s
This type of collision is a <u>Inelastic collision </u>
Explanation:
We begin by finding the momentum of the initial train car;
Remember that momentum is given by the formulae mass (kg) * velocity (m/s)
Therefore;
Momentum = 6000 * 10
= 60,000 kg⋅m/s
The other car has zero momentum because;
4000 * 0
= 0
When the two train cars collide, the total momentum will be;
60,000 + 0 = 60,000
Therefore to find the velocity, well use the same formulae;
p = mv whereby;
p – momentum
m – mass
v – velocity
60,000 = (6000 + 4000) * v
v = 60,000 / 10,000
v = 6
= 6 m/s
This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.
