@MTALHAHASSAN2

Answer 5

okay

Answer 6

now can u tell me
\[3ev=? joule\]

Answer 7

do u know
ev= electron volt

Answer 8

u can also write
joule =J

Answer 9

4.8x10^-19

Answer 10

u can write
J only for joule

Answer 11

unit plz !!

Answer 12

ur answer is correct !!

Answer 13

ok j

Answer 14

i think u r now able to find out
2ev=? J

Answer 15

plz tell me
2ev=? J

Answer 16

3.2x10^19 j

Answer 17

-19

Answer 18

right !!

Answer 19

how about this one?
The rest energy of an electron (m = 9.11 × 10-31 kg) in joules is:

A) 1.37 × 10-22 J

B) 2.73 × 10-22 J

C) 2.79 × 10-14 J

D) 4.1 × 10-14 J

E) 8.20 × 10-14 J

Answer 20

i think u know
\[E _{0}=m _{0}c ^{2}\]

Answer 21

\[E _{0}=\] = rest energy

Answer 22

\[m _{0}= \] rest mass

Answer 23

c= light velocity

Answer 24

now can u tell me
\[E _{0}=?\]

Answer 25

r u following me ?

Answer 26

just tell
yes=y
no=n

Answer 27

y
