If two students in a lab are asked to calculate the density of a block with a mass of 31.0 g; they are not told how many digits
Arada [10]

We can see here that the both measurements are accurate. This is the true because the both values are in the correct number of significant figures.

<h3>What is density?</h3>

The term density has to do with the ratio of the mass to the density of the object. We know that the accuracy of a measurement has a lot to do with the number of significant figures in the measurement. In this case, we are told that two students in a lab are asked to calculate the density of a block with a mass of 31.0 g; they are not told how many digits to round their measurements. Student A finds length to be 2 cm width to be 4 cm and height 8 cm. Student B finds the length to be 2.65 cm, width to be 4.20 cm, and height to be 8.35 cm.

For the first student, the density is obtained as;

Density = mass/ volume

= 31.0 g/ 2 cm * 4 cm *  8 cm

= 0.5 g/cm^3

For the second student;

Density = mass/ volume

= 31.0 g/2.65 cm * 4.20 cm * 8.35 cm

= 0.33 g/cm^3

A wave with a height of 10 feet and wavelength of 20 feet has a wave base of
SCORPION-xisa [38]
<h3><u>Answer;</u></h3>

10 ft

<h3><u>Explanation;</u></h3>

The wave base of a wave is the depth at which there is no more perturbation of the medium caused by the wave. The wave base of a wave is determined to be half the wavelength of the wave itself.

Therefore;

Wave base = wavelength/2

                   = 20 ft/2

                  <u> = 10 ft</u>
