The resistance of a wire Planning:- Introduction: To investigate the resistance of a wire at different lengths to see whether or not a longer wire has a larger resistance than a shorter wire. Apparatus: Wire Voltmeter Ammeter Battery 2 crocodile clips Metre rule Variable resistor Diagram: Variables: Length Thickness Resistance Material The material and diameter of the wire needs to be kept constant to keep the test fair as we are investigating resistance.

Section 1 WHAT IS HAPPENING IN THE WIRES? INTRODUCTION Electricity is usually invisible. Except for lightning and sparks‚ you never see it in daily life. However‚ light bulbs and a magnetic compass can show you when something electrical is happening. By observing their behavior and making a few assumptions‚ you can begin forming ideas about electricity. This type of thinking is called “building a model”. INVESTIGATION ONE: WHAT IS NEEDED TO LIGHT A BULB? 1.1 Activity: Lighting bulbs in a loop

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

North Coast Town – Poem Analysis The poem is set on the north coast of New South Wales. In Stanza 1‚ the persona is out beside the highway attempting to catch a ride. ‘Nothing much in my pockets but sand from the beach‚’ this suggests that the man slept on the beach the night and that it was pretty common for it to have occurred. The word ‘nothing’ is negative and is a sign of worthlessness. A Shell station is located near by as long as a hamburger stand both closed. The two utilities both represent

Microwaves can have a wavelength of 12 cm. A fire place can give off photons with a wavelength of 1.5 x 10-3 millimeters and the X-rays used in a dentist’s office have a wavelength of 2.1 x 10-11 meters. Ultraviolet rays‚ the ones that give you sunburn or fade the colors of clothes have

be found in a compound. And in order to detect the presence of metals in a compound‚ flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame. Flame test is fast and easy to perform. All the equipment needed for flame test is present in all chemistry laboratories. Solubility is a quantitative term defined

Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens

Man on Wire is a documentary about a goal oriented‚ thrill seeker that made history and created a masterpiece on a metal wire 110 stories above the streets of New York City. Philippe Petit had a dream to walk on a wire that was strung between the World Trade Centers. To make this happen it would take many years of planning‚ practice‚ and persistence. As we follow Petit through his journey‚ it becomes evident that he may not be able to achieve his goal. Director James Marsh allows tension to rise

their lives and throw you away when they don’t need you anymore. Philippe Petit‚ the main character of the documentary film “Man on Wire”‚ directed by James Marsh‚ is a great example of such a sucker. Barry Greenhouse‚ Petit’s accomplice‚ says it during the film‚ “He sort of draws you into his world.” Philippe was a brave‚ enthusiastic and persistent high-wire artist. His raw passion to walk hundreds of feet above the ground on a tightrope helped him to make his dream come true‚ and he became
