The supporting force exerted by a fluid on an object immersed in it is called ______.
2 answers:
Answer:
buoyant force
Explanation:
The buoyant force is the pressure that is exerted on a immersed object by the surrounding fluid.
The buoyant force acts on the surface of the solid object even if the object is immersed in the fluid partially or completely. If the object is immersed in a fluid, the net force is given by the formula:
where Patm is the atmospheric pressure at the top of the object
pgh = pressure of the part in the fluid
F(bottom) is the upward force on the object
The net force is the same as the wight of the displaced object.
The principle is known as the Archimedes principle as the buoyant force is equals the weight of the fluid displaced by the object.

Given that,
Mass of a tribble, m = 2.5 kg
Radius, r = 1.4 m
The force on the tribble from the bucket does not exceed 10 times its weight.
To find,
The maximum tangential speed.
Solution,
The force acting on the tribble is equal to the centripetal force.
F = 10mg
The formula for the centripetal force is given by :
v is maximum tangential speed
So, the maximum tangential speed is 11.7 m/s.
Explanation:
Recall the equation for time is distance divided by speed. Here you can use that to solve for "t".
