Which equation is not equivalent to the formula e = mc?
m equals e over c
c equals e over m
e = cm
m equals c over e
Please help THANKS!

Respuesta :

m equals c over e is not equal to e=mc

Answer with Step-by-step explanation:

we are given a equation:

e=mc

We have to find which equation is not equivalent to the above formula.

  • e=mc

Dividing both sides by c,we get

m=e/c

i.e. m equals e over c

  • e=mc

Dividing both sides by m,we get

c=e/m

i.e. c equals e over m

  • e=mc=cm
  • But m is not equal to c over e

Hence, The equation which is not equivalent to e=mc is:

m equals c over e
