When an unbalanced force acts on an object, the object accelerates. We can immediately rule out B and D, as friction changes based on the material and by applying a force the net force can’t be zero. It can be easy to say that the object will speed up after the force is applied (and it often does!), but take a braking car, for example. An external force of friction is applied to the brakes, causing an acceleration but in such a fashion that the car slows down. So, although an object can speed up after a force is applied, it isn’t always guaranteed.

Hope this helps!

An electric field of magnitude 2.35 V/m is oriented at an angle of 25.0° with respect to the positive z-direction. Determine the
zzz [600]

Answer:

The magnitude of the electric flux is 3.53\ N-m^2/C

Explanation:

Given that,

Electric field = 2.35 V/m

Angle = 25.0°

Area A= 1.65 m^2

We need to calculate the flux

Using formula of the magnetic flux

\phi=E\cdot A

\phi = EA\cos\theta

Where,

A = area

E = electric field

Put the value into the formula

\phi=2.35\times1.65\times\cos 25^{\circ}

\phi=2.35\times1.65\times0.91

\phi=3.53\ N-m^2/C

Hence, The magnitude of the electric flux is 3.53\ N-m^2/C
