Understanding Barometer Experiments

What is the primary function of a barometer as described in the video?

• To measure wind speed

• To measure humidity levels

• To measure temperature changes

• To measure atmospheric pressure

In the experiment with the physics textbook, what is the barometer used to measure?

• The speed of sound

• The weight of the book

• The temperature of the room

• The volume of the book

How is the change in pressure calculated when the book is placed on the barometer?

• By calculating the change in volume

• By measuring the temperature difference

• By observing the change in pressure readings

• By timing the duration of pressure application

What happens to the pressure reading as the barometer is submerged deeper into the water?

• The pressure fluctuates randomly

• The pressure decreases

• The pressure remains constant

• The pressure increases

Which formula is used to verify the pressure change in the water experiment?

• E=mc^2

• P=IV

• Rho gh

• F=ma
