Answer:
the pressure exerted by the fluid on its submerged surface
Explanation:
Flotation Force (Archimedes Principle):
If we have a body floating on the surface of a liquid or completely submerged inside it, the resulting force that keeps that body in position is called the "Flotation Force."
When a body is fully submerged in a fluid at rest, the fluid exerts hodrostatic pressure on each of the body parts in contact with the fluid. By the basic equation of the Fluid Static, at the same level h the forces exerted on the body due to the pressure are compensated, since they are equal in magnitude. However, the pressure exerted by the fluid on the lower part of the body will be greater than that exerted on its upper part, so the corresponding forces are different in magnitude and are not compensated. The resulting force due to the difference in hydrostatic pressures between level h2 and level h1 is the buoyant force. That is why this force always acts in a vertical and upward direction. If the floating body does not move, the floating force will be balancing the body weight.
Experimentally it can be verified that the buoyant force does not depend on the material from which the submerged object is made, but on the hydrostatic pressures exerted by the fluid on the volume of said object. That is why we can replace it with the surrounding fluid with its same shape and volume. This portion of fluid will experience the same state of pressures as the body in question.
The force needed to accelerate an elevator upward at a rate of is 2000 N or 2 kN.
<u>Explanation:
</u>
As per Newton's second law of motion, an object's acceleration is directly proportional to the external unbalanced force acting on it and inversely proportional to the mass of the object.
As the object given here is an elevator with mass 1000 kg and the acceleration is given as , the force needed to accelerate it can be obtained by taking the product of mass and acceleration.
So 2000 N or 2 kN amount of force is needed to accelerate the elevator upward at a rate of .
Answer:
D)535.024N
Explanation:
Hello! The most important thing to solve this exercise is to make a good free body diagram of the sled on the hill, our coordinate system is aligned with the slope while the direction of the weight force will always go down, then divide the weight vector into components and we found Wy, I attached the drawing!
Wy=mgcos24
Wy=(59.7)(9.81)(cos24)=535.024N
