Which quantity in the equation E equals mc2 represents the speed of light?

Speed of Light is represented by c. It is a constant, and is equal to 299,792,458 meters per second.


What is the quantity in the equation E equals mc represents the speed of light?

E = m*c2 E is energy. m is mass. c is the speed of light.


What is the physical quantity that is measured in light year?

A light year is a unit of distance, not a physical quantity. It represents the distance that light travels in one year in a vacuum.


What is the c in e equals mc2?

The letter 'c' in that equation represents the speed of light.


What does the c represent in the equation e equals mcs quared?

'c' represents the speed of light.


What is e in e equals mc2?

E=mc2 means energy=mass multiplied by the speed of light squared.


In E equals mc2 what does mc2 equal?

E represents energy, m represents mass, and c² is a very large number, the square of the speed of light.


How many is called in 1 light-year?

A light-year is a unit of distance, not quantity. It represents the distance that light travels in one year, which is about 9.46 trillion kilometers.


E equals mc2 what does the c stand for?

E=MC2The E represents the units of energyThe M represents the units of massThe C Represents the Speed of LightE=MC2 means Energy equals mass times the speed of light squared. Although this is not 100% correct it is very close!


If the equation E equals mc squared gives energy which is a scalar physical quantity how is this possible when multiplying a scalar and a vector results in a vector quantity?

Energy is a product of 1 scalar quantity which is mass and 1 vector quantity which is the velocity of light within a vacuum. The velocity of light in the equation is squared which returns an absolute value negating any sign it has. This results in both terms having no sign. A vector quantity must have both a direction and a magnitude. The product returned will always be a positive quantity which means it has no direction.
