Which is the most appropriate units for expressing angular velocity in kinematics problems?

Explanation:

The most appropriate units for expressing the angular velocity are the , since they are the units assigned for this magnitude in the International System of Units. Which is derived from the fact that radians are dimensionless and the second is the unit assigned for time in this unit system.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
