Calculate the heat capacity, in joules and in calories per degree, of 37.1 grams of water at 20 degrees Celsius. How many joules of energy are released when 45.0 g of water cools from 18.0 degrees C to 70.0 degrees C? The specific heat of water is 4.184 J/gC. ...
However, it is reported that more current can be provided by increasing the optional energy (more joules) on the biphasic AED equipment to achieve successful defibrillation.[4]Considering the variable energy, when the first shock at 200 joule (default initial energy) fails, the energy level for...
How many joules of nutritional energy are in a bag of chips whose label reads 247Cal ? \& Incorrect; Try Again; 2 attempts remaining This value corresponds to the units of kJ. Make sure that you have converted from Cal to cal before conver...
How many Joules of surge protection you need depends on a few factors like: What type of electronics you are protecting How often you experience power surges How long you want your surge protector to last But first, let’s dive deeper into what the hell “Joules” means. Who knows, it...
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...
A 5000 kg meteor is moving at 30,000 km per h. How many joules of kinetic energy does it have? If the mass of skater is 20 kg the height is 14 m velocity is 12 m/s, what is kinetic energy & what is potential energy?
Do you know how many zeros there are in a vigintillion? Someday, you may need to know this for science ormath class. Then again, you might just want to impress a friend or teacher. Numbers Bigger Than a Trillion The digit zero plays an important role as you count very largenumbers....
Gravitational potential (Jkg-1) = work done per unit mass to move a small object from infinity to that point (V=W/m). What are the units of gravitational potential? The units for gravitational potential would beJoules per kilogram.
A cube that measures 10.0 mm x 10.0 mm x 10.0 mm has a mass of 4.70 g what is its density in grams per milliliter? You are seeking to heat 200 ml of water for your morning cup of coffee from 20 degrees C to 100 degrees C. How much heat is required in joules?
