Answer: An equipotential surface must be perpendicular to the electric field at every point. The correct option is B.

Explanation: Equipotential surface is any surface over which the potential difference is constant. Examples include:

-The surface of a conductor in electrostatic field.

- surface of a liquid in equilibrium.

Equipotential surface are perpendicular to the electric field at every point because components of electric field intensity along the surface is zero ( this is because no work is done while moving a charge from one point to another on an equipotential surface).

The owner of a van installs a rear-window lens that has a focal length of -0.304 m. When the owner looks out through the lens at

Naddika [18.5K]

Answer:

$p =-1.03$

Explanation:

From the question we are told that:

Focal length of lens $f=-0.304 m$

Image distance $q=0.237 m$

Height of image $H_i=0.343$

Generally the lens equation is mathematically given by

$\frac{1}{f} = \frac{1}{q} - \frac{1}{p}$

Where $p$ is Subject

$p = \frac{(qf) }{(f - q)}$

$p = \frac{(-0.237)(-0.304)) }{((-0.304) - (0.237))}$

$p =-1.03$

Therefore the distance between the person and the car is

$p =-1.03$

What is the car’s average velocity (in m/s) in interval between t=1.0s to t=1.5s?

Lemur [1.5K]

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, the formula for velocity is;

Velocity (in m/s) = distance/time

The distance the car covered in the completed question is divided by the difference in the time interval

The difference in the time interval will be = 1.5s - 1.0s = 0.5s

NOTE: the distance must be in meters or be converted to meters
