Argon is a suitable choice for light bulbs because it's inert. Compared to a reactive gas like oxygen, the metal filimant would burn up in a reactive enviroment, which is why a noble gas is used.
The answer is 2.7gm/cm^3 . Density is mass divided by volume .
Pressure given by:
Pressure=(force)/(area)
Force=Mass*gravitational pull
Mass=34Kg
gravity=9.80
so,
force=34*9.8=333.2
thus;
pressure=333.2/25=13.328=13.3 N/cm^2
Hope this helped :)
Answer:
True
Explanation:
Atmospheric pressure reduces the amount of oxygen in the air, therefore leading to Hypoxia. Higher altitues contribute.
