point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57 N. It’s important to realize that getting a negative force value means the charges attract. The direction of that attraction is determined

Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

ROA‚ ANNA MARIA D. BA PSYCHOLOGY 1 Physics and Psychology—Relationship Status: It’s Complicated but Related One way or another‚ all things in life are related to one another. The same goes with Physics and Psychology. These two Sciences are different in a lot of ways but are also similar in certain aspects. Physics is the branch of Science concerned with the nature and properties of matter and energy. Psychology‚ on the other hand‚ is the scientific study of the mind and its functions

.Physics is the field of scince that controls the Earth‚ the Moon‚ the Sun and the Universe It is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration
