2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field‚ thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

The research proposed suggest that breast-fed babies are more intelligent than formula-fed babies. The independent variable is if a child was breast-fed or not. The dependent variable is the child’s IQ based on the Wechsler Adult Intelligence Scale (WAIS). Other important concepts to be understood is that this was a study and not an experiment‚ so the data could be skewed because it is based on the mothers self-reports of how much the child was breast-fed at the one-year examination.

Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the
