E=MC2 solve it

You make a big mistake here. That formula is for kilograms so you have to convert grams to kilograms first.

 C² speed of light squared     Mass in kilograms   Energy in Joules

↓                                                  .           ↓                ↓    

$${\mathtt{89\,875\,517\,873\,681\,764}}{\mathtt{\,\times\,}}{\mathtt{1\,230}} = {\mathtt{110\,546\,886\,984\,628\,569\,720}}$$

 

The Energy is in Joules

Units are important because some one might think it is in bullfarts or something.

Put it in this form

1.10547E+20 Joules

to make it easer to read. 

yes, you can find energy with the information you are given.

 

the formula is Energy = Mass * the speed of light squared.

 

given the speed of light and the mass, which you have as 1,230,000 g and 299,792,458 m/s all you have to do is PEMDAS to find the missing component of the equation.

using PEMDAS, the E is exponent, and M is multiplication. Therefore, you must first square the speed of light before multiplying it by your mass.

Energy = 1,230,000 g (Mass, m) * 299,792,458² (Speed of Light, c)

E= 1,230,000 *89,875,517,873,681,764

E= 110,546,886,984,628,569,720,000

Hope this helps!

 

Thanks Dragonlance :)

It appears anon that your answer is 1000 times too big.

If you were a physicist this would be a big error but for a maths exercise it is only a little error.  :)

 

So three points for both of you   :))
