Work: 1. A person pulls a toboggan for a distance of 35.0m along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution: A.) W=( 2.2x10^4N) ( 7.6 m)

HAZARD IDENTIFICATION‚ RISK ASSESMENT AND RISK CONTROL (HIRARC) In recent years‚ Hazard Identification‚ Risk Assessment and Risk Control (HIRARC) has become fundamental to the practice of planning‚ management and the operation of a business as a basic of risk management. The organizations that have carried out risk assessment at the work place have noted numerous changes in their working practice. Those who have already carried out risk assessment in their work‚ have reported positive changes

an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations‚ energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy. Kinetic energy is the energy a moving object has because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed. The kinetic energy of a moving object can be calculated from this equation: Kinetic

Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse

Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium pump. Thirdly‚ the molecular basis of the Action Potential will be

Dulce Et Decorm As much as we hate to have this happen most bad things can be interrupted into good thing. Some people like to think of “wars” as good events while others do not. Some think of them as ways that have given us freedom‚ hope and safety. However‚ in Dulce et Decorum est by Wilfred Owen he interprets the war as a sweet yet beautiful thing. Owen writes this poem to show the negative consequences of war. He does this by mimicking the war as a sweet yet beautiful thing. He describes

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement
