Physics Experimental investigations Will heating honey speed up how it falls from a spoon? The speed of falling of honey from an object depends on its viscosity. Viscosity is a measure of how much a fluid resists movement of a mass through it. It is the internal friction of a substance that causes it to be thick, sticky and adhesive. Apparatus needed for this investigation is: Electronic balance 750 grams of honey (around 530 mL / 530 cm3) Thermometer Bunsen burner / other source of heat /…

Most corrosion is an electrochemical reaction. Anything that affects the speed of the chemical reaction will in turn affect the amount of current flow, which will affect the rate of corrosion. The rate of corrosion is directly proportional to the amount of current in the electrochemical corrosion cell. If the current can be measured accurately, then an exact calculation of the metal loss can be made. 2.2.1 ELECTRICAL EFFECTS ON THE RATE OF CORROSION Any issue that have an effect on the…

There are billions of neurons in our brain that sends signals from the axon to the spinal cord. In the spinal cord the axon on will send signals to many neurons from other cells and then it will generate an order. The membrane potential is an electrical state of the cell membrane and it allows gradients that cause ions to move across the cell membrane. The dispersal of charge across the cell membrane is measured in (mV). The resting membrane potential is the difference between the charges…

near-perpetual motion of electrons. This was the basis of a modern day transformer, which basically adjusts the voltage of electricity. Without a transformer, houses would have to either supply very low voltage electricity, which would be used very quickly and therefore would prove to be very expensive and slow, or all electronics (phones, laptops, lights) would have to use very high voltage electricity, which would be an unimaginably dangerous hazard ("Nikola Tesla", American). All of these…

Ferroelectricity Among the ferroelectric materials, the static dielectric constant depends on the temperature under the relation: Curie – Weiss relation: €r = P + Q/ (T-Tc), (T> Tc), P, Q are constants temperature independent. C = Curie constant Tc = Curie temperature A transition in phase is observed at temperature Tc. Above this, the material remains in Paraelectric phase (the phase where the elementary dipoles of different crystal unit cells are…

Design and implementation of an Electronic system for identification of rebars in reinforced concrete. Abstract- In this paper non-destructive method is implemented in which magnetic self-designed sensor is used to detect position of rebar in reinforced concrete. During the renovation of old buildings it is necessary to locate rebar accurately to avoid damages in construction. This is achieved by Magnetic sensor which is made up of E-shaped core also primary and secondary windings. Due to…

batteries have the ability to charge and discharge more times than lead acid batteries, “nickel-cadmium battery can be charged and discharged over twice as many times as a lead-acid battery”. The nominal voltage of the nickel cadmium batteries is 1.2V. However, the lead acid batteries nominal voltage is 2V…

experiment, the teachers were given the list of questions to relay to the students behind a wall. The teacher is told that whenever the student gets a wrong answer he is supposed to apply electric voltage shocks to the student. Whenever the student gets a wrong answer higher the voltage Watts is increased. As the voltage got increasingly higher the student start to complain about how painful the electric shocks are getting. Most of the teachers were worried for the safety of the students and…

When voltage is applied to the electrodes containing the inert gas, light glows. The glow is produced when the voltage accelerates electrons to their maximum kinetic energy, and can only be produced when “the voltage is larger than the energy required to ‘ionize’ the atom” (Schiff 2). Voltage causes electrons to get taken out of their orbitals, resulting in the atoms they leave becoming positive…

4.1.2 Pipelined ADC The pipelined ADC is one of the most popular ADC architecture. The pipelined ADC architecture is similar to the sub-ranging ADC. The architecture of pipelined ADC is implemented by at least two or more low resolution flash ADCs. The pipelined ADC works from few M samples to more than hundred of M samples with resolution from 8 bit to 16 bits. Due to its high resolution and sampling rate range it is widely used in medical and communication applications like as CCD imaging,…
