How will you charge a glass rod by the method of friction

Physics
1 answer:
aniked [119]3 years ago
4 0

Answer:

<h2><em><u>A glass rod can be charged by rubbing it with silk cloth. When a glass rod is rubbed with silk, some of the electrons from the glass atoms are transferred to silk. Due to the deficiency of electrons in the glass atoms, it becomes positively charged.</u></em><em><u> </u></em></h2>

Explanation:

1. The Centauri star system consists of 3 stars and is about 4.37 light-years away from Earth. (A light-year is the distance that light travels in a year.)

2. We see the visible spectrum which consists of colors red, orange, yellow, green, blue, indigo, and violet. (The visible spectrum is the range of light that our eyes can detect.)

3. Because air has a lower index of refraction than water, the light beams making up the image of the fish I see bends as it leaves the water and enters the air. (Index of refraction determines how light bends when moving from one medium into another.)

4. When I look at my reflection in the mirror, the light reflects off the mirror at an equal but opposite angle as it hits the mirror.

5. When looking into a concave mirror the center is further away from you than the outside edges.  (Concave mirrors cave in.)

6. Forklift drivers are careful to look in the convex mirrors placed at blind intersections in the warehouse.

7. is transparent and the light goes through without distortion.

8. The electromagnetic spectrum refers to any or all of the possible wavelengths of "light", both the visible light and invisible light.

9. The transmission of light through a medium means it goes through it.

10. The absorption of light by a medium means it is absorbed by it.

В каких из перечисленных случаев тело приобретает потенциальную энергию? А) воду в реке поднимают с помощью плотины В) пуля выле
Dennis_Churaev [7]

Answer: D) a stone lies on the ground

Explanation:

Potential energy this is defined as the mechanical energy, energy stored, or energy created by the position of an object. Example; energy possessed by a ball while hanging at the top of a steep hill when about to roll down is called a potential energy. This is same as a stone which lies in a floor.

The current in a coil with a self-inductance of 1 mH is 2.8 A at t = 0, when the coil is shorted through a resistor. The total r
pogonyaev

Given:

L = 1 mH = 1\times 10^{-3} H

total Resistance, R = 11 \Omega

current at t = 0 s,

I_{o} = 2.8 A

Formula used:

I = I_{o}\times e^-{\frac{R}{L}t}

Solution:

Using the given formula:

current after t = 0.5 ms = 0.5\times 10^{-3} s

for the inductive circuit:

I = 2.8\times e^-{\frac{11}{1\times 10^{-3}}\times 0.5\times 10^{-3}}

I =   2.8\times e^-5.5

I =0.011 A
