Suppose you catch a salmon with a mass of 5kg. If all of its mass could be converted into energy how many Joules of energy would it produce?

It is Einstein's familiar E = mc2 that we use here. We know that c = 299,792,458 m/s and that c2 = (299,792,458 m/s)2 Got a 5 kgy fish to convert to energy? Let's do that. Using the International System of Units, joules are the units used to measure energy, kilograms are the units used for mass, and meters per second are used for speed. Note that 1 joule equals 1 kg-m2/s2. In unit-specific terms, E (in joules) = m (in kilograms) multiplied by (299,792,458 m/s)2. Let's begin by rounding cto 3 x 108 m/s to make things a bit simpler. That will give us a c2 of about 9 x 1016 m2/s2 and where 1 m2/s2 is a joule. E = mc2 and E = 5 kg times 9 x 1016 m2/s2 = 4.5 x 1017 kg-m2/s2 or 4.5 x 1017 joules of energy.

What is the rate at which energy is converted?
Joules
Suppose you catch a salmon with a mass of 5kg if all of its mass could be converted into energy it would produce how many Joules?
E = m c2A rest mass of 5 kg is equivalent to [ (5) x (3 x 108)2 ] = 4.5 x 1017 joules
How many amps in 200 joules?
200 joules of any other type of energy can be converted to 200 joules of heat.
What units are kinetic energy measured in?
To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
What is 12.56Nm in Joules?
Newton x meter is joules. (Please note that Nm is also used for torque; in this case, it happens to have the same units, but it is unrelated to energy, and can therefore not be converted to energy units.)
How do cells produce their energy?
They produce energy through a process known as cellular respiration. In it, glucose is converted into energy.
How is light energy converted into heat energy?
Light energy is converted into heat energy when plants take in sunlight (light energy) and convert it into heat energy when they respire and produce energy.
Describe a scenario where energy is converted from one form to another?
Yalll are suppose to help me -.-
What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
What is the rate at witch electrical energy is converted to another type of energy?
That is called "power". The SI unit for power is the watt, which is equal to joules/second.
How long will it take to produce 150kw from 780 joules of energy?
If you can stuff the 780 Joules of energy through the system in 0.0052 second,then the power during that time is780/0.0052 = 150,000 watts.But it only lasts for that 5.2 milliseconds, and then you're out of joules.
