Answer: 18 blocks in total ( 17 add to the original in contact with the ground)
Explanation:
The pressure on the face in contact with the ground ( we choose the face 0.15m x 0.082m)
Pressure= Force ( weigth) /Area
1 Atm = 101325 Pascal [N/ m^2]
The answer is C sorry if it’s wrong
Explanation:
We have,
Distance traveled in a circular track is 500 miles
The winning time was 3 hours and 13 minutes. It means time is 3.217 hours.
The driver's average speed is given by total distance divided by total time taken. Its formula can be written as :

At the end of the race, the driver reaches the point form where he has started. It means the displacement of the driver is equal to 0. Hence, driver's average velocity is equal to 0.
Answer:
The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal magnitude and in opposite directions, they balance each other.
