These questions are of which topic?

3. anonymous

for the first problem what do you think you should use ?

4. anonymous

i don't understand this. period.

5. anonymous

ah

6. anonymous

so there is this general notion about the relationship of mass and energy. what they have in common is that they are both conserved, meaning that they are neither created nor destroyed.

7. anonymous

in the famous formula proposed by Einstein, $$E = mc^2$$ it shows a great deal of relationship that energy and mass have a proportional relationship since the speed of light is constant

8. sweetburger

I may be thinking wrong but would you take the mass and mulitply it by the speed of light squared to find the energy

9. anonymous

words and equations. my brain is fried.

10. anonymous

it is easy all the numbers you need to work with are given remember that the only constant is the speed of light and the rest are relative

11. arindameducationusc

Is the answer 1.008 * 10^16....

12. arindameducationusc

I also dont know but its interesting...

13. anonymous

what does each variable stand for?

14. sweetburger

E = energy M = mass C = speed of light

15. sweetburger

E=m(C^2)

16. sweetburger

the equation allows for the conversion between mass and energy

17. anonymous

OMG THERE IS NO SPEED OF LIGHT IN THE FIRST QUESTION (SORRY MY CAPS KEY IS STUCK, IM FIXING IT)

18. anonymous

use the constant speed of light $$\large 3.0 \times 10^8 \sf ~ms^{-1}$$

19. sweetburger

^

20. anonymous

it is easier to use the approximated value rather than be bogged down with the 2.9 ......... crap the purpose is to be able to know how to convert mass and energy

21. anonymous

MY HEAD HUrts so bad. where did you get the ms ^ -1 ?

22. sweetburger

its a measure of speed so its in meters per second...

23. sweetburger

ms^-1 is the same thing as m/s

24. anonymous

I am using $$ms^{-1}$$ instead of $$\large \frac{m}{s}$$

25. anonymous

either im too dumb for this or otherwise but i think i kind of sort of got grasp of it

26. anonymous

if you remember in algebra lesson with the laws of exponent $$\huge \frac{1}{x} = x^{-1}$$

27. sweetburger

@aric200 thats what pm's are for

#mathisnotfun

30. arindameducationusc

Is the answer 1.008 * 10^16.... Can anyone check this? @hwyl

31. anonymous

I don't think you're that dumb, you just didn't do your part of the reading to familiarize yourself with the concept :P

32. anonymous

what is this reading you speak of?

33. sweetburger

34. anonymous

if you want to skip the reading portion just watch and take down notes https://www.youtube.com/watch?v=ql6TKCo2SZQ

35. anonymous

no sir i am homeschooled, and the online books are well as fun as a blind guy has watching tv

36. anonymous

take notes down

37. anonymous

are you sure its not a link to where you got your pfp from?

38. anonymous

;)

39. sweetburger

bozeman science is fantastic

40. anonymous

ya great for HS stuff

41. anonymous

i lie bill nye

42. anonymous

like* i also cant type , every nerve in my brain is doing salsa

43. sweetburger

haha XD

44. anonymous

you think i would kid around at 4 in the morning about my brain doing salsa? whats wonr with yuo
