The maximum frictional force in the knee joint of a person who supports 76. 0 kg of her mass on that knee 119.28N.
Given,
m=76kg, μ=0.16, g=9.81 m/
frictional force = mμg= 76*0.16*9.81= 119.28 N
<h3>Frictional force</h3>
An opposing force to the relative motion of two bodies in contact is known as frictional force. Always acting in the opposite direction from the direction of motion, frictional force is applied to a moving body. Because it resists motion, it aids in lowering the moving object's speed. The force is one of touch. Four broad categories can be made for the force of friction depending on the sort of motion that occurs between the two objects. Static friction is the force of friction between an object and the surface it is put on.

The parts of the cell are mitochondria, lysosomes, ribosomes etc. Their functions are as follows :
(1) Vesicle is a one of the large structure within the cell. Its function is to transfer materials out of the cell.
(2) Mitochondria is also called the power house of the cell. Its function is to break down sugar to supply energy for the cell.
(3) Lysosomes are the suicidal bag of the cell. It breaks down waste and other materials of the cell.
(4) Endoplasmic reticulum helps to produce, process and transport proteins in vesicles to the Golgi apparatus.
Answer:
A
Explanation:
• Nina experiences a force equal to f.
Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.
