Answer:
A red and white speckled chicken.
Explanation:
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.

From the given clauses and phrases, the independent clause can stand alone as a complete sentence while the dependent clause can not.
<h3>What are clauses?</h3>
Clauses are groups of words that contain a subject and a verb that are related together.
Clauses can be dependent or independent clauses.
A phrase is a group of words that do not contain a subject but may contain a verb.
Based on the given options:
- The independent clause is scientists create this plants and animals through genetic engineering.
- The dependent clause is " so that people can choose whether or not to consume these foods".
- The infinitive phrase is "to consume these foods "
- The gerund phrase is "the labelling of these foods".
Therefore, the independent clause can stand alone while the dependent clause can not.

Answer:
The correct answer will be- Crop rotation
Explanation:
When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.
Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.
The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".
Thus, crop rotation is the correct answer.
