I need help with all questions thankyou! 10. If you walk along the top of a...

when you walk on a fence then you spread your hands so that you can increase your moment of inertia and as total angular momentum is conserved so so if we moment of inertia then angular velocity is reduced and we can balance on the fence otherwise if angular velocity is more then there are chances of falling down

in a racing car the front wheel is kept at far from rear wheel so that it's center of mass lies attached to the ground and it experiences less torque while accelerating .

when car falls off from a cliff then it experience a torque due to it's weight about the edge of cliff and rotates while falling down

The braking forces create a rotating tendency, or torque, about the CG. Imagine pulling a table cloth out from under some glasses and candelabra. These objects would have a tendency to tip or rotate over, and the tendency is greater for taller objects and is greater the harder you pull on the cloth. The rotational tendency of a car under braking is due to identical physics. The braking torque acts in such a way as to put the car up on its nose .

for same angle of incline

for a bowling ball (solid sphere ) acceleration = 5/2 sin(theta)

for volley ball (shell) acceleration = 3/2 sin(theta)

so acceleration of bowling ball is more than a volley ball

please upload other questions separately

we can answer only first four according to HOMEWORKLIB RULES

please rate it up thanks :)
