Answer:
1) joule
2)
3)
Explanation:
1) Luminosity is the <u>amount of light emitted</u> (measured in Joule) by an object in a unit of<u> time</u> (measured in seconds). Hence in SI units luminosity is expressed as joules per second (), which is equal to Watts ().
This amount of light emitted is also called radiated electromagnetic power, and when this is measured in relation with time, the result is also called radiant power emitted by a light-emitting object.
Therefore, if we want to calculate luminosity the Joule as a unit will be used.
2) Work is expressed as force multiplied by the distane :
Where force has units of and distance units of .
If we input the units we will have:
This is 1Joule () in the SI system, which is also equal to
3) The formula to calculate the percent error is:
Where:
is the experimental value
is the accepted value
This is the percent error
Answer:
Explanation:
Given data
Mass m=2.46×10⁻²⁶kg
Voltage V=270 V
Magnetic field B=0.5353 T
To find
Radius r
Solution
By using conservation of energy to find speed of charge
Substitute the given values
So the radius can be find as:
Substitute the values
The answer would be Exosphere because, there are 3 main regions that circulate oxygen through the Earths system, which are the Biosphere, Atmosphere, and the Lithosphere.
After the remains of living organisms (plants and animals) were buried under the layers of the earth's crust, they were exposed to very high temperatures and pressures, which led to the concentration of carbon in it and thus turning it into fossil fuels used to produce fossil energy.
The composition of fossil fuels depends on the carbon cycle in nature, and is extracted from fossil materials such as coal, black petroleum coal, natural gas, and petroleum.
