Summary
The problem is based upon Coulomb's law. The force between the two charges is inversely proportional to the square of the distance between them. Therefore, as distance between the charges increases, the force becomes lesser by an amount of the square of the increment.

But, if the value of resistors is different, the current through the resistor will be different, and accordingly the power dissipated by the resistor will be different.
Step-Up Transformer: Such a transformer, steps up the voltage at the secondary windings. In such a transformer, the number of turns in secondary windings is more than that in primary windings. The proportion in which voltage will be stepped up depends upon the proportion in which the numbers of windings are more in the secondary windings.
Step-Down Transformer: As the name suggests, step down transformer is used to lower the voltage. In such a transformer, the numbers of turns in secondary winding are less than the number of turns in primary. If the numbers of turns in the secondary are half than the primary, then the voltage in the secondary will be half of the primary voltage. Therefore, transformer is a useful device used in AC circuits for dividing or multiplying the voltage levels.
This rule is also applicable to electrically charged particles. Two like charges repel each other while two opposite charges attract each other. The force between the charged particles is defined by the Coulomb's law.

In such a transformer, the number of turns in secondary windings is more than that in primary windings. The proportion in which voltage will be stepped up depends upon the proportion in which the numbers of windings are more in the secondary windings.
Voltage transformation ratio =
(Number of turns in secondary-N1) / (Number of turns in primary-N2)
For example, If the number of turns in secondary windings are double than primary winding than the voltage will be doubled.

...? Physics Phy 1 The Law of Momentum Conservation s that without any external forces acting on a system, the moment of the system would not change (Serway & Jewett, 2009). But moving objects encounter opposing external forces and lose momentum to zero thus stopping. 2. When jumping from a tree to the ground, the person moves at constant acceleration hence constant force. On hitting the ground, the person experiences an opposing force from the ground causing the body to lose momentum within a short time interval, hence need for more force leading to pain. 3. The balloon would initially be at rest with zero momentum. On release, the gases initially inflated move in one direction and the balloon would move in the opposite...

... The figure below shows two boats, of which one is sunk and the other is afloat. If we consider the floating boat as boat and the sunken boat asboat 2, then we can see that boat 1 has air within it and water around it, whereas boat 2 has water around it as well as inside it. The magnitude of the buoyancy force on an object depends upon the volume of the water that it displaces. In boat 1, the air inside the boat also serves as a means of displacing water. Whereas in boat 2, only the boat’s material itself is displacing the water; its inside is filled with water, thus that volume is not getting displaced. Thus as boat 1 is displacing more volume of water than boat 2, it has a higher buoyancy force subjected upon it. Clearly... The figure below ...

...? Physics The universe is so large and enormous that it cannot be explained in words nor can be imagined by any one. Our earth which feels and seems to us very large is in actual equivalent to a small dust particle in comparison to the enormous universe. Universe consists of a number of different elements. The universe comprises of millions of super clusters. These super clusters consist of hundreds of different sized galaxies. Of such a super cluster is our earth a part of. The super cluster consists of galaxies in the form of groups. The galaxy in which earth is situated is called Milky Way and is situated in a group called the local group which comprises of more than 30 galaxies (Caprara & Harris, 2003). The Milky Way is made... ...

...INTRODUCTION TO PHYSICS The word "physics" is derived from "physis" which means natural development. However physics is the science that studies therelation between matter and energy, thereby gives an integrated outlook to physical phenomena. Even as early as 16th century, the concept of physics inspired many great scientists like Galileo, Newton. But it gained an independent identity in 19th century. New discoveries constantly open new outlook for learning about nature. It is a way of looking at nature from the ground up, and has inspired the philosophies of the twentieth century. Today, the scope of physics is expanding through...

...What is your benefit of this Here are the following points I learned from the concerning Newton’s first and second laws of motion, measuring and static friction and gravity. In Newton’s first law of motion, the basic relationship between change of velocity and interaction is a significant highlight (Chabay & Sherwood, 2011, p.6). This is also known as the law of inertia, stating that an object at rest remains at rest unless acted on by an unbalanced force and an object in motion continues in motion having the same speed and direction unless acted on by an unbalanced force. This therefore means that without unbalanced forces, objects have the tendency to do what they are initially doing. We are living in a society where we do... is your...

...Physics Assignment Physics Assignment In studying the motion that results when an object moves under the influence of gravitythe following principles have applied. The first principal used is Newton’s law of universal gravitation. It states that two objects exert a force of attraction on each other, and the force experienced is along the line joining the two objects. The second principal is the Newton’s laws of motion that have been used to calculate the displacement, velocity and acceleration of objects under the influence of gravity either in free fall or in inclined motion. The experiment intends to answer the following questions: How does the position and velocity change with time? How does the weight...
