Answer:learn vocabulary, terms,and more with flashcards, games,and other study tools.size of an objects displacement could be greater than the distance the object travels.
Explanation:
given that
initial velocity of car = 0 m/s
after t = 10 s
final velocity of the car = 25 m/s
now for average acceleration we can use
<em>so here the acceleration will be 2.5 m/s^2</em>
Answer:
See explanation
Explanation:
Nuclear energy refers to energy trapped in the nucleus of atoms. Nuclear energy holds the greatest promise for large scale electricity generation. For instance, the amount of energy released by a given mass of uranium is 2.5 million times the energy released by combustion of an equal mass of carbon.One gram of uranium produces the same energy as 1 ton of coal, 17000 cubic feet of natural gas, 5000 pounds of wood and 149 gallons of oil.
Nuclear energy does not pollute the atmosphere as fossil fuels do. However, the challenges of effective control of the nuclear reactor and disposal of radioactive waste still remain a serious concern.
However, exploitation of nuclear energy as a source of electricity remain expensive and it is not quite easy to set up a nuclear power plant. Not many countries can afford to pay for the services of experts who operate nuclear energy plants talk more of providing the required equipment.

Explanation:
Note: You did not provide the diagram you mentioned but I will explain to you the sequence of events that take place as a fluid cools. I believe you can apply this to the particular diagram that you have.
Sequence of events that take place as a fluid cools down:
- There is a reduction in the temperature of the fluid
- The speed of movement of the molecules will reduce
- Since there is a reduction in speed, the Kinetic Energy also reduces. KE = 1/2 mv²
- The density of the fluid will increase as the temperature decreases
- The molecules will be closer to each other as opposed to in a gas where there is collision of molecules
