'Investigate the factors which affect the strength of an electromagnet'
... I thought that this factor would give me the most reliable results. The current I will keep constant at 0.2 amps, the thickness of the wire I have used for the coils will stay the same for both experiments. The ...

An Experiment to investigate the change of speed of light through perspex.
... refraction ? b and the refractive indices na and nb of the media are related through what has become known as Snell's Law: Equation na Sin ? a = nb Sin ? b Prediction My first prediction is that the angle of ...

An Experiment to Measure the Speed of Light in Glass.
... know that when light goes through a different medium from which it is already in (a vacuum for example) it slows down, this is caused by there being more particles in the way. Light refracts because the change in speed, ...

An Investigation Into the Effect of Wave Exposure on the Volume of Limpets
... a result of the force of the water's acceleration increasing at a faster rate than the organisms ability to hold on as an organism grows, wave exposure prevents the distribution of larger limpets. When limpets are mobile their adhesive tenacity ...

An Investigation into the Effect on the Critical Angle by Changing the Colour of Light
... the opposite side. Again the angle of incidence is greater than the critical angle. This is then repeated all the way to the end of the cable where the information is needed. Practical applications include digital audio transmitters which allow ...

An investigation into the factors affecting the frequency of a standing wave
... be fair, then the two other factors affecting the frequency must be kept constant for the results to be accurate. I have decided to investigate the effect that altering the length of string along which the wave travels. From the above ...

An Investigation to Determine the Effect of the Number of Turns around the Core of an Electromagnet on its Strength.
... results. We discovered that with and iron nail core, the magnetic strength below twenty turns was not high enough to produce measurable results on a discrete scale such as number of paperclips. In the case of voltage we found that ...

Are Recent Extreme Weather Events, Like the Large Number of Atlantic Hurricanes in 1995, Due to Global Warming?
... example, there has been a clear trend to fewer extremely low minimum temperatures in several widely separated areas in recent decades (e.g., Australia, the United States, Russia, and China). The impact of such changes can manifest itself in fewer freezing ...

ATRAC: Adaptive Transform Acoustic Coding for MiniDisc
... time of 74 minutes. The ATRAC (Adaptive Transform Acoustic Coding) data compression system was therefor designed to meet the following criteria: * Compression of 16-bit 44.1 kHz stereo audio into less than 1/5 of the original data rate with minimal ...

Carry out an experiment to find a relationship between the incident angle and the refracted angle when light is shone through a rectangular Perspex block.
... an angle; one edge of the light beam slows down before the other. This causes the light to bend towards the normal until both edges are travelling at the same speed. The normal is the line from where the angled ...

Describe and explain how a simple radio receiver and transceiver works and then explain one of its uses in an ILS (Instrument Landing System).
... This means that it will 'help' the pilot of an aircraft fitted with ILS equipment to make an approach to an airport that is equipped with ILS transmitting equipment. Although it sounds very simple a design it is actually rather ...

Domain Theory - Experiment Plan
... each time because this will take too much time and may not work out so that my experiment will be a fair test. Also I will not be able to change the core of the electromagnet due to the resources ...

During this coursework practical, we aim to study the behaviour of water waves at various depths of water.
... of water, and the speed is calculated for each water depth (speed = distance ÷ time). DIAGRAM PRELIMINARY WORK Before the real coursework experiment, some preliminary investigations were conducted. We experimented with the tank being filled with just one particular water depth, ...

Effect Of Tension On Resonance And Amplitude
... plucked and the applied frequency equals its natural frequency then resonance occurs. The resonant frequency of a string can be increased by: * Shortening the length * Increasing the tension * Using a lighter string Variables and Constants The experiment is basically concerned with the effect ...
