What two things will affect size of the electric force between two objects?​

Physics
1 answer:
tatyana61 [14]3 years ago
4 0

<u>Answer:</u>

The two things that affect the size of the electric force between two objects are "amount of charge on each object and distance between the charges".

<u>Explanation:</u>

The magnitude and sign of the electric force are estimated by the electric charge in "Coulombs Law" inspite of mass an object which is favorable in gravitational force. Therefore charge is the property of electromagnetism which influences the charged objects' motion.

More the charge on object more will be the electric force, as bigger charge cloud have more force than smaller.The electric force is inversely proportional to the square of the distance between the two charges. This showcase weaker attraction or repulsion as the distance increases between the two charges.

Which of the following about Dalton's theory of matter is true?
Lemur [1.5K]
D.Atoms can be divided into smaller parts.


Dalton's atomic theory was the first complete attempt to describe allmatter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that allmatter is made of atoms, which are indivisible.

If light energy to electric energy conversion using solar cells is 12 % efficient, how many square miles of land must be covered
umka2103 [35]

Complete Question

The light energy that falls on a square meter of ground over the course of a typical sunny day is about 20 MJ . The average rate of electric energy consumption in one house is 1.0 kW .

If light energy to electric energy conversion using solar cells is 12 % efficient, how many square miles of land must be covered with solar cells to supply the electrical energy for 350000 houses? Assume there is no cloud cover.

Answer:

The area is  A = 1.26 *10^{7} m^2

Explanation:

From the question we are told that

      The efficiency is  \eta =12%

      The number of houses is  N = 350000

       The light energy per day is E =  20 \ MJ

       The average rating of electric energy for a house is  E_h  =  1.0 \ k W =  1000W

   

Generally the electric energy which the solar cells covering 1 \ m^2 produces in a day is

       E_s =  \eta * E

           E_s =  0.12 * 20*10^{6}

          E_s = 2.4 MJ m^{-2}

Energy for required by one house for one day is  

        E_H  = E_h * 1 \ day  

       E_H  = 1000 * 24 * 3600  

        E_H  = 86.4 MJ

Energy needed for 350000 house is

      E_z = 86.4 *10^{6} *  350000  

     E_z = 3.02 *10^{7} MJ

The area covered is mathematically represented as

            A = \frac{3.02*10^{7} \ MJ}{2.4 \ MJ m^{-2}}

           A = 1.26 *10^{7} m^2

Calculate the power expended by peter who carries a 11 kg box 6m high in 3s
yawa3891 [41]

Given that,

Mass of a box, m = 11 kg

It is lifted to a height of 6 m

Time, t = 3s

To find,

The power experienced by the Peter.

Solution,

Power = rate of doing work

P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{11\times 9.8\times 6}{3}\\\\P=215.6\ W

So, the power experienced by the Peter is 215.6  Watts.

Differentiate scalars &amp; vectors?
o-na [289]
A scalar quantity is a one dimensional measurement of a quantity, like temperature, or mass. A vector has more than one number associated with it. A simple example is velocity. It has a magnitude, called speed, as well as a direction, like North or Southwest or 10 degrees west of North.
