Answer:
Friction is a force that tends to oppose the relative motion between two bodies in contact. Frictional force always acts on a moving body from the direction opposite to the direction of motion. It opposes the motion, and therefore, helps to reduce the speed of the moving object. It is a contact force.
Answer
given,
expression of Kinetic energy of rotating body

ω = 34.0 rad/s
Assuming mass of the particle equal to 13 Kg
and perpendicular distance from the particle to the axis is r = 1.25 m
now,
moment of inertia of particle = ?
from the given expression
..............(1)
we know

v = r ω

putting value in equation (1)



I = 20.3125 kg.m²
Answer:
2666.7 N/m
Explanation:
Spring constant = force / displacement
k = F / x
k = 400 N / 0.15 m
k = 2666.7 N/m
445/100 - 5/4 = 445/100 - 125/100 = 320/100 = 16/5 = 3 1/5.
Glenohumeral joint arthritis is caused by the destruction of the cartilage layer covering the bones in the glenohumeral joint. This creates a bone-on-bone environment, which encourages the body to produce osteophytes (bone spurs). Friction between the humerus and the glenoid increases, so the shoulder no longer moves smoothly or comfortably
