Hi again!
The correct answer for the kinetic energy of the car is 484,000 joules.
We can find this by using the formula. The formula for kinetic energy is m
Knowing this we can fill in the formula using the info we were provided. Doing this we get: (2,000 · )
= 484
2,000 · 484 = 968,000
· 968,000 = 484,000

Question 9: Anthony has more power than Angel
We can see Anthony gets done with the same work quicker than Angel. But they did the same amount of work, just Anthony was quicker. Power is the rate at which work is done. Knowing this we can see the answer is Anthony has more power than Angel.
I hope those answers help u!
Good luck! :)
Answer:
Raising its temperature by
Explanation:
The specific heat capacity of a substance is defined as the amount of energy needed to raise the temperature of 1 kg of a substance by .
The specific heat capacity of a substance essentially tells us how much energy is needed to heat the substance: the larger it is, the more energy is needed. The amount of energy needed to increase the temperature of a substance is given by
where
m is the mass of the substance
Cs is the specific heat capacity
is the temperature variation of the substance
The correct option is B.
There are many hazards that may occur as a result of globalization. One of this is the violation of human right by companies. This can occur in several ways, for instance, there are some companies from developed countries which introduce hazardous technological devices to less developing countries.
This question involves the concepts of equilibrium and Newton's third law of motion.
The support force will be "1 pound" for the empty bucket and the support force will be "6 pounds" after pouring water into it.
- According to the condition of equilibrium, the sum of forces acting on a stationary object must be zero. Hence, the support force of the table will be equal to the total mass of the bucket.
- According to Newton's Third Law of Motion every action force has an equal but opposite reaction force. Hence, the support force will be a reaction force to the weight of the bucket.
Therefore, the support force in each case will be equal to the total mass of the bucket:
Case 1 (empty bucket):
<u>support force = 1 pound</u>
<u></u>
Case 1 (water poured):
support force = 1 pound + 5 pound
<u>support force = 6 pound</u>
<u></u>
