Answer:
The pressure produced on the air in the pump is 37.209 pounds per square inch.
Explanation:
By definition, the pressure is the force exerted on the piston divided by its area. Given that, force is distributed uniformly on the piston area, the formula to determine the pressure is:
Where:
- Pressure, measured in pounds per square inch.
- Force exerted on the piston, measured in pounds.
- Piston area, measured in square inches.
If 
and 
, the pressure produced on the air in the pump is:
The pressure produced on the air in the pump is 37.209 pounds per square inch.
Answer:
Explanation:
Given that,
Displacement in North = 11 km
Displacement in East = 11 km
We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :
Hence, the approximate displacement of the hiker from the camp is 
.
Isaac Newton compared the acceleration of the moon to the acceleration of objects on earth. Believing that gravitational forces were responsible for each, Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth's center from the object's center. But distance is not the only variable affecting the magnitude of a gravitational force. Consider Newton's famous equation
