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>

No because an atom consists of <u>two</u> main parts <em>and</em> <u>three</u> subatomic particles - protons, neutrons, electrons. Each one is smaller than an atom, therefore they are subatomic particles. An atom only requires protons and electrons to be an atom - e.g. Hydrogen has 1 proton and 1 electron. Neutrons do not affect the overall charge of the atom, and only increase the atomic mass.
Answer:
Energy dissipated = 13.453 Joules
Explanation:
In order to solve this problem, we first compute the gravitational potential energy the child has, and then find the kinetic energy at the lowest position.
The gravitational potential energy (relative to lowest position) is found as follows:
G.P.E = mass * gravity * height
Where, Height = 2 - 2 * Cos(34°)
Height = 0.3193 meters
G.P.E = 30 * 9.8 * 0.3193
G.P.E = 93.874 J
Kinetic energy:
K.E = 0.5 * mass * velocity^2
K.E = 0.5 * 30 * 2.31547^2
K.E = 80.421 J
Energy dissipated = G.P.E - K.E
Energy dissipated = 93.874 - 80.421
<u>Energy dissipated = 13.453 J</u>
Answer:
0.5 hours or 30 minutes
Explanation:
each hour travels 80km
so, time taken= 40/80 hours
= 0.5 hours
= 30 minutes
The role of thermal energy is to balance the electrical energy lost from the light bulb.
<h3>
Energy conservation</h3>
The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.
<h3>Thermal energy</h3>
This is a form of energy that occurs due to rise in temperature.
The role of thermal energy is to balance the electrical energy lost from the light bulb.
