is characteristic of active dreaming. This is called REM, and is a well
known phenomenon.. Hope that helps!</span>
Answer:
2
Explanation:
Hello to solve this problem we must initially draw the free body diagram of the car, and remember that for a body to be in balance the sum of its moments must be zero.
When this equation is raised, we can find the relationship between the forces of the front and rear wheel, and the complete procedure is attached.
For acceleration, there needs to be three factors that come into play. Either the change in velocity is increasing, decreasing, or it is changing direction. On a circular track, the direction is always changing. Which fits one of the three factors. So your answer would be A.
Answer:
Its internal energy decreases by 40 J.
Explanation:
The energy supplied to the metal block causes the temperature of the block to rise. Therefore,

Now, we will use this value of mC to find out the energy change of block:

It shows that when the temperature of the metal block falls by 10°C,
<u>Its internal energy decreases by 40 J.</u>
