Answer:
The minimum gauge pressure is 0.4969 atm.
Explanation:
Given that,
Density = 1040 kg/m³
Height = 4.94 cm
We need to calculate the pressure
Using formula of pressure
Where, 
=density
h = height
Put the value into the formula
Pressure in atmospheres
Hence, The minimum gauge pressure is 0.4969 atm.
B. Ask a question - Hypothesize - Experiment - Analyze - Draw a conclusion
Explanation:
The scientific method is a systematic approach in which investigations are conducted in science.
It follows systematic manner;
- An observation in nature is made using the senses.
- Questions are then asked about such observations. This is the inquiry phase.
