Answer:
200 mL
Explanation:
Given that,
Initial volume, V₁ = 300 mL
Initial pressure, P₁ = 0.5 kPa
Final pressure, P₂ = 0.75 kPa
We need to find the final volume of the sample if pressure is increased at constant temperature. It is based on Boyle's law. Its mathematical form is given by :

V₂ is the final volume

So, the final volume of the sample is 200 mL.
According to funtriva.com, the piece that allows you to adjust the amount of light that's coming through the microscope is called the adjustable diaphragm. It is located under to stage (where what you are observing is placed on) and can be rotated to make the light<span> intensity change</span>
Are breathing hard. This is because cardiovascular exercise makes the heart beat faster which in turn creates a need for more air.
Answer:
a) 2.33 m/s
b) 5.21 m/s
c) 882 m³
Explanation:
Using the concept of continuity equation
for flow through pipes

Where,
A = Area of cross-section
V = Velocity of fluid at the particular cross-section
given:


a) 
substituting the values in the continuity equation, we get

or

or

b) 
substituting the values in the continuity equation, we get

or

or

c) we have,
Discharge
thus from the given value, we get


Also,
Discharge
given time = 1 hour = 1 ×3600 seconds
substituting the value of discharge and time in the above equation, we get

or

volume of flow =
