Answer:0.0704 kg
Explanation:
Given
initial Absolute pressure
=210+101.325=311.325



as the volume remains constant therefore



therefore Gauge pressure is 337.44-101.325=236.117 KPa
Initial mass 

Final mass 

Therefore
=0.91-0.839=0.0704 kg of air needs to be removed to get initial pressure back
Answer:
yeah
Explanation:
as wavelength increases frequency decreases and it goes the same for the opposite way
Answer:
1.28second
Explanation:
The speed of light is constant everywhere, it is
299,792,458m/s=299,792.458km/s
Therefore it takes
