Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 1.2 x 10-8 C and they are separated by a distance of 0.40 m. 2.

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a

The following is a project made by anonymous: INTRODUCTION The general purpose photoconductive cell is also known as LDR – light dependent resistor. It is a type of semiconductor and its conductivity changes with proportional change in the intensity of light. There are two common types of materials used to manufacture the photoconductive cells. They are Cadmium Sulphide (CdS) and Cadmium Selenide (CdSe). Extrinsic devices have impurities added‚ which have a ground state energy closer to the conduction

Science in the Big City: Exploring Career Opportunities in the Natural and Physical Sciences New York City May 13-18‚ 2014 Students in the Natural Sciences at the University of Houston-Downtown are generally accomplished and motivated students with strong interests in science. However‚ students typically have a very limited perception of the science careers available to them outside of medicine. To educate students as to the array of potential careers available in the sciences (not medicine)

Space Definitions Field Vector A field vector is a single vector that describes the strengths and direction of a uniform vector field. For a gravitational field‚ the field vector is g Weight Weight is defined as the force on a mass due to the gravitational field of a large celestial body such as the Earth Gravitational Potential Energy Gravitational Potential Energy is the energy of a mass due to its position within a gravitational field. On a large scale GPE is defined as the work done

Step 1: The hand holding the the weight in the pendulum will release the weight and allow it to swing forward to hit the car. This is potential energy by the force of motion of the weight on the pendulum. Potential energy is the energy an object produces due to its position. The pendulum swinging is it being in motion therefore it has kinetic energy. The force shown form this could be Applied Force. Applied force is a force that is applied to an object by a person or another object. Step 2: After

Mass media has become an integral part of our lives and can not be separated from our life. Particularly for the urban people‚ the need for information is more important than ever. Our values and way of life in the society in this information era are strongly influenced by the mass media like newspapers‚ TV‚ radio‚ video‚ and the internet. Mass media’s influence on people’s lives is even greater and deeper than many kinds of state indoctrination or priest’s sermons from the pulpit in the church
