5.0x10^12

Honestly, I've never seen this before, but I think you convert kW-h to J and use E = mcÂ˛

can you walk me through changing it to joules please

okay hold on

1 kilowatt hour =
3 600 000 joules

convert it your Kwh into joules then put it in E=MC^2

E being your energy in jouls ....and C being the speed of light

use SI units

so 5.0*10^12=5,000,000,000,000

now multiply it by 3 600 000

yu get your enerygy in jouls then

don t get rid of the exponantional notation here ...it help keeps the number small

so 1.8*10^19j

3 600 000 x (your enrgy in Kwh) = MC^2
you need to fing out M

J*

yeah ... there ya go ^_^

and than the equation i need is M=E/C^2

correct?

yes

good work

So M=1.8*10^19J/299792458m/s

gottta change m/s to J

everything should be in SI units ....like meter for distance jouls for energy ...

so what do i do than

So M=1.8*10^19J/299792458m/s you said this was your answer right ?

yes but isnt there something more i have to do

that figure is your answer .... express it in kilograms and your all set

how do i express it in kilograms

just do 1.8*10^19/299792458 and add the alphabets Kg in the end

would you believe it i am driving right now ....and i pull over to the side to answer your questions

are you clear on this ?

haha thank you so much

feel free to ask .... i am in the parking lot now

Would you help me with one more question if i post it

No problem bro

depends if i can solve it myself .... ... hit me with it
