AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

ABSTRACT This study aims to make an improvised traveling charger that will use heat or waste heat to charge a battery. It is not new to us that we are lacking for the supply of the electricity and being in the modern times‚ we can’t live without cell phones and how does we able to charge the battery if there’s no supply of electricity. The researcher used scrap materials that can be easily found. They used copper and iron plate‚ some adhesives copper wires and the normal traveling charger to construct

an electronic wave packet in the unifonn field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more then one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination ofparameters of such packet by powerful laser pulse scattered with is discussed. The motion of one-electron wave packet in the nonuniform

magnetic properties of lodestone (magnetic iron ore) were known‚ the magnetic compass had been in use for some time by navigators‚ and the amber effect (now called the triboelectric effect)‚ by which amber and certain other materials acquire a static charge when rubbed was also known. But no one could adequately explain how or why such things worked. Gilbert’s experiments meant that he developed a number of his own theories. One important theory was that the magnetic effect exhibited by the lodestone

partial negative charge while hydrogen has a partial positive charge. Hydrogen bonding is generally stronger than most bonds bar covalent bonds. Water: Bonding within water molecules occur between oxygen and hydrogen. These covalent bonds mean that the electrons are shared between the oxygen and hydrogen atoms to create a complete valence shell. However‚ electrons tend to spend more time around the oxygen atom due to its higher electro-negativity. This creates a partial positive charge around the hydrogen

Applying statistical mechanics‚ the number of moving charge carriers is given by: where is a function of the temperature which scales as ‚ is Boltzmann’s constant‚ and is the band gap (the energy separation between the

The History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity

But there is an opportunity for us in price. Even though they have automation of ten they are still charging 30 for their low tech products. This is an opportunity for us to charge less! What actions should you take to compete with this competitor more effectively? We also have automation of ten and are going to charge less‚ and spend a lot on our sales so out product is much more accessible. Our products are pretty much the same so because we are charging less we should be able to take some
