Answer:
Waning Gibbous is correct
Answer:
170N
Explanation:
First add 530N to 150N and you get 680N, then add 400N to 450N and get 850N. So subtract 850N by 680N and you get 170N
Answer:
Explanation:
Given:
volume of air in the room,
temperature of the room,
<u>Saturation water vapor pressure at any temperature T K is given as:</u>
<u /><u />
putting T=298 K we have
<u>The no. of moles of water molecules that this volume of air can hold is:</u>
Using Ideal gas law,
is the maximum capacity of the given volume of air to hold the moisture.
Currently we have 80% of n, so the mass of 20% of n:
where;
M= molecular mass of water
is the mass of water that can vaporize further.
The only correct statement on that list is <em>choice-C</em>: If a positively charged rod is brought close to a positively charged object, the two objects will repel.
