Given below is an equation of a wave: ` y = r sin omega (x//v - kpi)`. What are the dimensions of x and k? Here `omega` is angular velocity and v linear velocity.

in a wave motion, y= a (sin9k x- omega t), y can represent

KE of a rotating body is given by 1/2 I omega^2 ,where l is moment of inertia and omega is nagular velocity of the body.Find the dimensions of I.

Write the relation between linear velocity (v),angular velocity(omega) and radius of circle(r).

What is the relation between angular velocity omega , frequenct v and time period T?

A star like the sun has several bodies moving around it at different distances. Consider that all of them are moving in circular orbits. Let r be the distance of the body frm the centre of the star and let its linear velocity be v, angular velocity omega , kinetic energy K, gravitational potential energy U, total energy E and angular momentum p. As the radius r of the orbit increases, determine which of the above quantities increase and which one decrease.

State whether the equation y=y_0 sin (2pi)/v t is correct ,wherer t is time and v is velocity.

If a body is moving in a circle of radius r centimetre at a constant speed of v cms^-1 , then its angular velocity is

The equation of a simple harmonic wave is given by y=3 sin pi/2 (50 t-x) where x and y are in mtres and t is in seconds.The ratio of maximum particle velocity to the wave velocity is :
