$A$ particle is moving in a horizontal circle with constant speed. It has constant

Consider an object making uniform motion around a circle of radius $5 \ m$ with tangential velocity $2 \ ms^{-1}$. The time it takes to complete $2$ revolutions and the magnitude of acceleration respectively are

$A$ particle is moving in uniform circular motion. About which point in the plane of the circle will the angular momentum of the particle always remain conserved?

"$A$ particle moving with constant speed on a circle about a fixed axis has a constant angular velocity,but its linear velocity is not constant." Is this possible? Why?

In uniform circular motion,

Is the statement "Angular position $\theta$ is a scalar,whereas angular displacement is a vector" correct?
