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.

Explanation
In Science when you have large data-sets of a Food product then you have to provide its description, Quality and Quality. Here is example for each part as,
Description:
The scientist have to describe the features of Corn grown in different soils. Corn length could be variable in different soils depending upon the nutrient contents of them.
Quality:
For any food product quality is most important factor. Scientist have to explain about the quality of Corn grown in different soils because each soil have a different environment of seed growth.
Quantity:
Finally, the data for the quantity will explain that which soil was more suitable to obtain higher yield of corn.
1.) B.) plants have chloroplasts
2.) B.) to prevent hydrophilic heads from sticking
3.) B , D and maybe C?
