Describe the process to measure the volume of coins using water
Fill a measuring cylinder with a known volume of water, add coins, and measure the new water level.
How does a micrometer work for measurement?
It uses a screw mechanism to measure small distances with great precision.
What is the volume of a sphere with a radius of 5 cm?
524 cm3
How can parallax error affect measurements?
t occurs when the measurement is read from an angle rather than straight on, leading to inaccurate readings.
