A electron is released from rest in a uniform electric field oriented from left to right. What happens to the electric potential

energy of the proton-electric field system?A. IncreaseB. DecreaseC. Remains the same
Physics
1 answer:
True [87]4 years ago
4 0

Answer:

Explanation:

When electron is released in an electric field , it will move in the direction opposite to the direction of field. In this process , force is applied by the field and work is done by the field. So its electric potential energy will be decreased because , its energy is converted into kinetic energy of the electron .

If an object starts at rest and moves 60 meters north along a straight line for 2 seconds, what is its average velocity?
ELEN [110]
Answer is d 30 m/s, North

Given: Distance d = 60 m;     Time  t = 2 seconds

Required: Average Velocity  Vave. Vi + Vf/2

Formula: d = 1/2 at²   derive acceleration a = ?   and       a = Vf - Vi/t

               a = 2d/t²
             
               a = 1/2(60 m)/( 2 s)²

               a = 30 m/s²

Solve for final Velocity   Vf = ?

               a = Vf -Vi/t

               Vf = at     Since Initial Velocity is zero

               Vf = (30 m/s²)(2 s)

               Vf = 60 S


For average velocity Vave. = Vi + Vf/2

                                 Vave. 0 + 60 m/s/2

                                 Vave = 30 m/s  North.

All the stars in this photo are at about the same distance from Earth (some 25,000 light-years away). Which stars in this pictur
givi [52]

Answer:

You did not add the photo, but the bright red stars are the largest in size (radius).

Explanation:

Red stars are giant, luminous stars. They are the stars with the largest size (radius) among all the other stars and usually have very low temperatures (below 500k). The brighter these stars appear to human eyes, the greater their actual size.

Red stars have rays hundreds of times larger than the sun, literally being the biggest stars in space. Despite their gigantic size, these stars have low density.
