W = `1/2 kx^2` in this equation find out the dimension of k, where w = stored potential energy and x = eloxgation of the spring.

y = A sin(omega t- kx) Cm this equation find out the dimension of omega ?

Find out the dimension of K in the equation, W= (1)/(2) Kx^(2) . Here x and W are the elongation and the potential energy respectively of a spring.

In the following equations, find whether variables x, y, z etc. represent rational or irrational numbers w^(2)=27

Statement I: The restoring force F on a stretched string at extension x is related to the potential energy U as F=-(dU)/(dx) Statement II: F=-kx and U=1/2 kx^2 , where k is the spring constant.
