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

Current‚ Voltage and Power * Electricity is the flow of electric charge. We can describe the flow of electric charge in several ways. These include the quantities Current‚ Voltage and Power. Current * Current (I) is the rate of flow of Charge Carriers‚ such as electrons. Current is usually thought of as moving in the direction of positive charge‚ so from the positive power supply to the negative. However‚ since in metals it is electrons that carry electric charge‚ the actually flow is opposite

"Cut" is one of Sylvia Plath’s best confessional poems.It has been dedicated to Susan O’Neill Roe‚Plath’s nurse and a close friend during the period of her single motherhood.It is narrated by a woman who has just cut her thumb while slicing an onion.It has been written in a free verse and has ten‚four-line stanzas. The poet begins by saying‚ "What a thrill".She considers having cut her thumb to be exciting and interesting.The top part of her thumb has been cut of and a small hinge of skin is left

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

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity

BOOM’ S PROBLEM PS 4.3 – Torque (Rotational Equilibrium) Problems 1. A crane supports a 3.0 kN weight as shown. The crane’s boom is 8.0 m long and is at an angle of 30˚ from the horizontal. If the hydraulic support is attached to the boom 2.0 m from the bottom of the boom‚ then: a) what is the compressional force in the hydraulic? b) what is the magnitude and direction of the force on the pin at the bottom of the boom? a) ∑Torque = 0 F cos 30˚ x 2.0 = 3000 cos 30˚ x 8.0 F = 24

Next would be how you hold the guitar while sitting or standing. This is a very simple technique and very hard to do incorrectly. The back of the guitar will be flush against your midsection. If the guitar covers most of your torso‚ then it may be too big. If it is too big‚ it will be difficult to play smoothly. Now that you know how to hold the guitar‚ and where to put your hands‚ you should know how to put the strap on the guitar‚ simply referred to as “strapping the guitar”. Both ends of the strap
