Answer:
Workdone =0
Explanation:
The body is inclined at θ=30°, s=10m, m=5kg
Workdone by the object = FsCosθ
but the surface is a friction-less surface, this means coefficient of friction =0
F=μR
F=0*R
F=0
W=FScosθ
W=0*SCosθ
W=0

No you can not
atleast as far as i know
Answer:
In longitudinal waves, particles travel in the direction parallel to that of the wave motion where as in transverse waves, particles move perpendicular to the direction of the wave motion and in surface waves, particles in the medium move in a circular motion.A good example of longitudinal waves is sound waves. Vibrating a string on the ground can serve as an example of transverse wave.For surface waves, the ocean waves travelling on the surface can illustrate the cicular movement of particles in the water.
