Scientists currently monitor underground movements, such as earthquakes and nuclear tests, using seismometers – instruments that measure the motion of those events at the Earth's surface.

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.

4, any other option is a mix between dna and rna, or describes rna
Answer:
<em>The correct option is D) The energy of the car will decrease, and the energy of the block will increase. </em>
Explanation:
As we know energy cannot be created or destroyed but it can change from one form to another. When the wooden car will collide with the wooden block, some of the kinetic energy with which the car was moving will be passed to the wooden block. As a result, the wooden block will also get pushed along the track. Meanwhile, as the wooden car had transferred some of its energy, its energy level will decrease and it will move slower than before pushing the wooden block along with it.
