Joules: A joule (J) is defined as the standard unit for energy alongside the calories (cal). And energy is defined as the capacity of any individual to do work. So we can conclude that we spend or exchange energy in order to do an activity or work. ...
An electron has been accelerated from rest through a potential difference of 800 V. What is the electron's kinetic energy, in electron volts? What is the electron's kinetic energy, in joules? What is How fast must an electron move so that its total energy is 32% more than its rest mas...
We measure natural gas by volume converted to a measure of energy. The metric standard for energy content is joules (J). Your bill is based on the amount of energy you use, measured in gigajoules or a billion joules.
If a fire starts in the northwest corner of a skyscraper floor, by the time the fire reaches the southeast corner, the starting fire at the starting point will have burned through most of the fuel, and the fire will not be as intense. The result is the fire doesn't put maximum strain...
This involves swapping my 'normal' rotor disc for a new 'off-set' version. To aid changing discs back and forth for comparison tests, the base unit layout was also altered to give quicker and easier access. The practical work on this is now all done, with testing due in Oct 2015. In...
There is no runaway, uncontrolled chain reaction in a nuclear power plant.How does a nuclear power plant work? Okay, we've figured how to get energy from an atom, but the energy we've got isn't that helpful: it's just a huge amount of heat! How do we turn that into something ...
Inside your gas-operated water heater is a tiny gas flame called a pilot light, whose purpose is to ignite the burner whenever the temperature falls below the thermostat setting. Right next to the pilot light is a small metallic tube known as a thermocouple. Buthow does a thermocouple work,...
If you drop a 13.0-kg ball from a height of 30 m (neglect friction), how many joules of kinetic energy will it have when it is halfway through its fall? You are holding a 2 kg ball 25 m above the ground. How much kinetic energy does the...
Setting expectations is an important part of a business relationship, and an engagement letter makes these expectations clear on both sides. The client gets the reassurance of knowing when a service will be completed, how much it will cost, and the specifics of the scope of work. The letter ...
A finance lease transfers the asset and any risk or return to the lessee. This means that ownership is transferred in a financial lease to the entity that leases the asset. In an operating lease, the ownership remains with the lessor, the entity that leased the asset to the lessee. What ...
