Which of the following statements is a consequence of the equation e = mc2?
a. energy is released when matter is destroyed.

b. mass and energy are equivalent.

c. the law of conservation of energy must be modified to state that mass and energy are conserved in any process.
d. all of the above

Answer;

B. Mass and energy are equivalent.

Explanation;

-Each of the letters of E = mc2 stands for a particular physical quantity.

E is the energy, m is the mass and c is the speed of light (m/s)

 Energy = mass x the speed of light squared

-The equation E=mc2 explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass. It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.

-The equation tells us that mass and energy are related, and, in those rare instances where mass is converted totally into energy, how much energy that will be.

its a 5.5 n

glad that

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
