Answer:energy which a body possesses by virtue of being in motion.
Explanation:
fluid friction<span> occurs when an object moves through a liquid or gas. the force needed to overcome </span>fluid friction <span>is usually less then that needed to overcome </span>sliding friction<span>. the </span>fluid<span> keeps the surface from making direct contact and thus </span>reducing friction<span>.</span>
Answer:
The answer is D.
Explanation:
Just took the quiz. Not sure if u still need help
Energy is destroyed because animals are higher levels do not need as much energy. That is option B.
<h3>Energy movement in a food chain</h3>
Food chain is defined as the sequence that shows the feeding relationship between different organisms and how energy flows from the producers to decomposers.
The producers which are the plants traps in energy from the sunlight with the help of their green pigment called the chlorophyll.
The energy continuously flows from the producers to consumers and then to the decomposers.
From the law of conservation of energy, it is neither created nor destroyed.
Therefore energy is destroyed because animals at higher levels do not need as much energy, is not a valid statement.

Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
