Derive equation for parabolic water surface formed in a rotating beaker partially filled with water using slope method.

• Assume the beaker is rotating with angular velocity w about its axis

• Use the slope method to derive the equation for the parabolic water surface formed

• The equation is y = (1/2) * (w^2/g) * x^2, where y is the height of the water surface and x is the distance from the axis of rotation

• This equation is a r...read more

Flux through solid angle is the amount of flow of a vector field through a given solid angle.

• Flux through solid angle is a measure of the amount of flow of a vector field through a given solid angle.

• It is calculated by integrating the dot product of the vector field and the unit normal to the surface over the solid angle.

• The unit of flux through solid angle is steradian (sr).

• It is used in various fields such as optics,...read more
