Timed, does anyone know the answer to this physics question?

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

1 a

2 b

3 b

4 d

5 d

6 d

explanation:

frequency or wavelenth of em radiation in a vacuum

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
