If a rectangular area is rotated in a uniform electric field from the position where the maximum electric flux goes through it t
denpristay [2]

Answer:

D) 30°

Explanation:

This is in accordance to the Gauss Law which states that, <em>the electric flux through any closed surface is equal to the total charge enclosed by the surface divided by the permittivity of free space.</em>

Mathematically given as:

\phi=E.A\ cos \theta=\frac{Q_{enc}}{\epsilon_0}

where

θ = the angle between the electric field lines and area vector normal to the surface.

When the area vector has formed an angle of 60° then the plane is at 30° and we know <em>cos 60° = 0.5</em>

A 65 kg cart travels at a constant speed of 4.6 m/s. What is its kinetic energy?
Talja [164]

Answer:

Explanation:

mass (m) = 65 kg

velocity (v) = 4.6 m/s

Kinetic energy (KE)

= 1/2 * m * v²

= 1/2 * 65 * 4.6²

=  687.7 J

hope it helps :)
