Answer:
C. 500 watts
Explanation:
power is defined as the rate of work done

When a force causes a object to move, work is being done on the object by the force.


Answer:
Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.
Explanation:
Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.
<h2>Nitrogen is Conserved</h2>
Explanation:
- Nitrogen is a basic component of all life forms.
- It is found in all proteins and DNA molecules.
- Nitrogen is available in the earth's atmosphere by 78 % as N2 gas.
- In nitrogen fixation, bacteria convert nitrogen gas into ammonia or usable form of nitrogen used by plants., When animals eat the plants, they acquire usable nitrogen compounds.
- During the nitrogen cycle, nitrogen atoms used in the cycle are neither created or destroyed, or changed into other atoms.
- Thus it can be said that the law of conservation of matter is related to the nitrogen cycle, which states that matter is never created or destroyed in any chemical or physical process.
Answer:
The answer is 34.119m
Explanation:
You need to pay attention to the word "uniformly". It means there is no acceleration thus the physics of this problem respond to the uniform rectilinear motion equations:
- Xf = Xo + vt
- v = constant
- a = 0
where:
- v = velocity (speed)
- t = time
- a = acceleration
Xf = 0 + (15.3)(2.23)
Xf = 34.119m
