Answer: The partial pressure of 
if the total pressure of the mixture is 3.9 atm is 0.975 atm
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction of nitrogen in solution = 0.25
= partial pressure of nitrogen = ?
= Total pressure = 3.9 atm
Putting in the values :
The partial pressure of is 0.975 atm
Answer:
S=2.693m
Explanation:
Let point 
be the origin of the room and the fly is crawling at point 
as shown in the attached photo:
#Distance of the fly from the corner of the room is defined as:
#Substitute the coordinate values in the above equation:
Hence, the distance of the fly from the corner of the room is 2.693m
Answer:
41.5 m/s
Explanation:
Since there are no external forces, momentum must be conserved.
Momentum P = mv.
Total momentum before the collision:
Total momentum after the collision:
solving for v:
Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.
Answer:
Rigorous exercise
Explanation:
For your heart rate is been around 100 bpm you should be doing a rigorous exercise . but if ain't doing any rigorous exercise and your heart rate is constantly above 100 bpm you should consult your doctor.
An average heart is between 60 bpm to 100 bpm.
