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.

Rainforest cover only 2 % of the total surface area of the Earth but in spite of that about 50 % of plants and animals that live on the Earth live there.
By definition rainforests are forests that recieve high amounts of rainfall so you can actually find rainforests in Alaska for example (other examples: Canada, Asia, Africa, Latin and South-America)
About 1/4 of natural medicines are found in rainforests. 70 % or more of the plants that are used to treat cancer are found only in tropical rainforest on the planet.
Trees in tropical rainforests are so dense that it takes approximately 10 min for the rainfall to reach the ground from canopy.

Explanation:
Do to the fact that Earth's axis is tilted 23.5 degrees to the plane of the "ecliptic", which is the plane of the Earth's orbit around the Sun. Each planet's orbital plane is a little different from Earth's, and each planet has a different axial tilt. The fact that we are talking about 5 dgrees we are talking about Jupiter which there would be little to no change
Answer:
During telophase nuclear membrane is formed, nucleolus appears and astral rays disappear.
During telophase, the effects of prophase and prometaphase - the nuclear membrane and nucleolus disintegrating are reversed. Two daughter nuclei form in each daughter cell, and phosphatases dephosphorylate the nuclear lamins at the ends of the cell, forming nuclear envelopes around each nucleus.
