Answer:
Scientific explanation is aimed at shedding light into natural phenomenon through the use of measurement results and observations.
The groups to benefit from the claim are:
- People who sell coffee with caffeine
- Diners that serve coffee with caffeine
- Soda manufacturers that sell caffeinated drinks
- Manufactures of caffeinated energy sports drink
The above selection are correct due to the following reasons:
The claim in the question is: <em>"Caffeine improves mental alertness and motor coordination"</em>
The assertions of the claim are:
- Caffeine improves mental alertness, meaning that by taking caffeine, a person becomes more alert and/or aware of the environment as well as being able to keep up better at task, which are desirable for work related activities
- Caffeine improves motor coordination; Motor coordination refers to the ability to involve multiple parts of the body to achieve complex motion. The ability to improve motor coordination can create demand for caffeine among active people
Based on the above association of caffeine to benefits that are desired by active people, (working people that generate income), the groups that would benefit most from the claim are, the dealers in caffeinated products including:
- <u>People who sell coffee with caffeine</u>
- <u>Diners that serve coffee with caffeine</u>
- <u>Soda manufacturers that sell caffeinated drinks</u>
- <u>Manufactures of caffeinated energy sports drinks</u>

The working equation for this one is:
E = F/Q, where E is the strength of the electric field, F is the electric force and Q is the charge. Substituting the corresponding values, the strength of the electric field is equal to
E = -30 nN/-3 nC
E = 10 nN/nC
Answer:
example of adaptation in mangrove
Mangroves are salt-tolerant trees, also called halophytes, and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen conditions of waterlogged mud.
adaptation of rainforest
Many animals have adapted to the unique conditions of the tropical rainforests.

Answer:
Explanation:
Change in length of spring = 2.13 m
Component of weight acting on spring = mg sinθ
so
mg sinθ = k x where k is spring constant and x is total stretch due to force on the spring.
Here x = 2.13
mg sin17 = k x 2.13
31 x 9.8 sin17 = k x 2.13
k = 41.7 N/m
b ) In case surface had friction , spring would have stretched by less distance .
It is so because , the work done by gravity in stretching down is stored as potential energy in spring . In case of dissipative force like friction , it also takes up some energy in the form of heat etc so spring stretches less.
