Free electrons may be transferred between bodies by "Contact Action"

When positively charged body comes close to a negatively charged body, then electron flows from positively to negatively charged body

In short, Your Answer would be Option B

Hope this helps!

Answer:

B) contact action

Explanation:

When two conductors are connected with each other then in that case the free charge of one conductor may be transferred to other if the potential of one conductor is not same as the potential of other conductor.

As we know that positive charge always move from higher potential to lower potential.

So here when two bodies are connected together then in that case electron from one body is transferred to other body if the the potential of two bodies are not same.

So here correct answer will be

B) contact action

Take the mechanical equivalent of heat as 4 J/cal. A 10-g bullet moving at 2000 m/s plunges

klasskru [66]

Assuming that all the bullet’s energy heats the paraffin, its final temperature is 27.1 degree C. The correct option is D.

<h3>What is temperature?</h3>

Temperature is the degree of hotness and coldness of the material.

The energy of the bullet E = 1/2 mv²

E = 1/2 x 10 x 10⁻³ x (2000)²

E = 2 x 10⁴ J

This heat is used in heating the paraffin

E = m x c ΔT = m x c (Tfinal -Tinitial)

2 x 10⁴ J = 1 x 2.8 x 10³ x (Tfinal -20)

Tfinal = 27.1°C

Thus, the final temperature is 27.1 degree C. The correct option is D.

Which radiation has a higher frequency than visible light

Bogdan [553]

Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves.

Arace car accelerates uniformly at 11.3 m/s2. If the race car starts from rest how fast will it

Ganezh [65]

Answer:

75.71 m/s

Explanation:

From equation of motion, acceleration is given by

$a=\frac {v-u}{t}$ where v is the final velocity, u is the initial velocity and t is time taken.

Making v the subject of the above formula

v=at+u

Substituting 6.7 s for time, t and 11.3 for a and taking u as zero since it starts from rest

v=11.3*6.7=75.71 m/s
