I think it's D)!!!!!!!!!!
Explanation:
F=ma=(100kg)(4m/s/s)=400N
N is Newton, the SI unit of force, which is a kg•m/s/s. F is net force and, of course, m is mass and a is acceleration.
A machine can alter an input force<span> by changing its (1) magnitude, or (2) direction. All</span>machines<span> are subject to energy conservation in that no </span>machine can<span> output more energy (do more work) than the energy put into it.</span>
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>
