<span>Two objects move toward each other because of gravitational attraction. As the objects get closer and closer, the force between them increases. </span>
Answer:
Explanation:
Here the total force at the horizontal components will be equal to the centripetal force on the car. So we will have:
(1)
- f(fr) is the friction force
- N is the normal force
Now, the sum of forces at the vertical direction is equal to 0.
(2)
Let's combine (1) and (2) to find f(fr)
I hope it helps you!
You would have done 240 joules of work on the box.
Work = (force) x (distance)
= (60 newtons) x (4 meters)
= 240 joules .
Force necessary to support the object on piston 2 is 24× 10⁴ N.
To find the answer, we need to know about the force and pressure on piston 1 and piston 2.
<h3>What's the pressure on piston 2?</h3>
- The force on piston 2= mass × acceleration due to gravity
= 991 Kg × 9.8 = 9414.5N
- Mathematically, force= pressure/area
- Pressure= force × area of piston
= 9414.5N × π(9.46² cm² /4)
= 9414.5N × π(9.46²× 10^(-4)m²/4)
= 66.2 N/m²
<h3>What's the force needed to held the mass on piston 2?</h3>
- Pressure on piston 2 = pressure on piston 1
- Force on piston 1= pressure on piston 1/area of piston 1
= 66.2/ π(1.87² cm² /4)
= 66.2/ π(1.87²×10^(-4)m² /4)
= 24× 10⁴ N
Thus, we can conclude that force necessary to support the object on piston 2 is 24× 10⁴ N.
