The critical angle formula should be: sin^-1(1/n)
where "n" is 1.501 into the air
<span>The critical angle of light travelling from benzene, happens because the larger angles of incidence from the inside of the benzene has experienced the total internal reflection. </span>
Explanation:
It is given that initially pressure of ideal gas is 4.00 atm and its temperature is 350 K. Let us assume that the final pressure is
and final temperature is
.
(a) We know that for a monoatomic gas, value of
is \frac{5}{3}[/tex].
And, in case of adiabatic process,
= constant
also, PV = nRT
So, here
= 350 K,
, and 
Hence, 

= 267 K
Also,
= 4.0 atm,
, and 


= 2.04 atm
Hence, for monoatomic gas final pressure is 2.04 atm and final temperature is 267 K.
(b) For diatomic gas, value of
is \frac{7}{5}[/tex].
As,
= constant
also, PV = nRT
= 350 K,
, and 


= 289 K
And,
= 4.0 atm,
, and 


= 2.27 atm
Hence, for diatomic gas final pressure is 2.27 atm and final temperature is 289 K.
Um I would help you but I don’t see the question
4095km
Explanation:
Given parameters:
Starting time = 7 o'clock
Stopping time = 11hrs 30min
Speed = 910km/hr
Unknown:
Distance covered = ?
Solution:
Speed is the rate of change of distance with time.
It is a scalar quantity that is with respect with magnitude but no direction.
Speed = 
Distance = Speed x time
Time taken = time between 11hrs 30min and 7 o'clock = 4.5hrs
Input the parameters:
Distance = 910km/hr x 4.5hrs = 4095km
