Use the equation PV=nRT to find no. of moles (n)
For this;
At STP
Pressure= P= 1 atm
Temperature=T = 273.16 K
Volume= V= 16.3 L = 16.3 dm³
R = 0.0821 dm³ atm K⁻¹ mol⁻¹
Now,
PV= nRT
(1)(16.3)=n(0.0821)(273.16)
n = 0.727 mol
Now, again using the same equation for
Pressure=P= 735 torr
Temperature=T= 57°C
T= 57+273 =330 K
n= 0.727 mol (form previous calculation)
R= 62.4 dm³ torr K⁻¹ mol⁻¹
Now,
PV= nRT
(735)V= (0.727)(62.4)(330)
V= 20.37 dm³

The airtime is 9.8
the velocity is 0
Answer:
0.629 m
Explanation:
For destructive interference we have the case
m = 1,2,3.....
Frequency is given by
Wavelength
The angle
The width is
The width of the hole is 0.629 m
For destructive interference
The angles are
If earth was not tilted on a axis, we wouldn't have any seasons. we wouldn't have seasons because the axis tilts us towards or away from the sun, and if you're tilted torwards the sun the sun you would have summer. if you're tilted away from the sun, you have winter. if there was no axis, the temperature would be the same all around the earth, so therefore we would not have seasons.
hopefully this helps
