When someone lifts a book from the ground, the work you use is positive. By lifting the book, you change it's energy and it's original place The book gains, kinectic energy.
Hope I helped.
The kinetic energy of an object is directly proportional to its mass, and to the square of its velocity.
Resistance = Voltage/Current
Wattage = Voltage * Current

That means the current drawn by the lamp is equal to 100 watts divided by 210 volts.

Answer: Qualifying as an Olympian is an extremely difficult feat for anyone to accomplish and is regarded as a very prestigious title. To qualify as a Paralympian is an even tougher challenge. ForParalympic athletes, the sports in which Olympians compete are harder to do, harder to train for, and pose challenges that would prove nearly impossible for a fully able-bodied person to overcome. The disparity in level of difficulty between the same sports in Olympics and Paralympics was evident to me when watching the events. Whether skiing down a mountain, swimming, or playing on ice, Paralympic athletes must demonstrate a higher level of skill in order to succeed in their respective event.
Answer:
Explanation:
The only one that doesn't have a time unit that is squared is the one that is a label for speed or velocity. Acceleration has a label with the time unit squared, like m/s/s. Choice D is the only unit for speed/velocity.
