Explanation:
<span>The scientists use data
and measurement to obtain empirical evidence. Data can be collected through
direct observation or else experimentation. Empirical measurements and data can
be gathered by using qualitative and quantitative methods. Empirical evidence
contains the recording and analyzing the data which is a central part of scientific

Answer:
The mass of the boulder remains constant, while its weight decreases with respect to the value of gravitational force on the moon.
Explanation:
The mass of the boulder = 15 kg
On the earth, its mass remains 15 kg. But its weight is;
weight = m x g
= 15 x 9.8
= 147 N
The boulder's weight on the earth is 147 N.
When transferred to the moon, the mass remains constant i.e 15 kg. But its weight decreases due to a change in the value of acceleration due to gravity on the moon. Thus, the boulder becomes lighter in weight.
