The density of an object can be calculated using the formula Density = Mass/Volume. In this case however we are searching for the volume and must rearrange the formula so that we are solving for the volume. If you multiply both sides by volume and then divide both sides by mass you end up with the equation Volume = Mass/Density.
Volume = 1500g/1.5g/cm^3
Volume = 1000 cm^3
Answer:
225 m
Explanation:
= Frequency of the T wave = 6.8 Hz
= Speed of sound in seawater = 1530 ms⁻¹
= Wavelength of the T wave
we know that, frequency, speed and wavelength are related as
Inserting the values, we get
