Mass is how heavy is it, weight is the size both are the same
<span>Force = Work done / distance = 4Nm / 2m = 2N</span>
A calorimeter measures the amount of heat in a chemical reaction. So the answer would be C, specific heat.
Answer: 7200 m
Explanation: The solution is, first convert 15 minutes to seconds.
15 mins x 60 s / 1 min = 900 s
Use the formula for speed which is v= d/t then derive for d.
d = vt
= 8 m/s ( 900s)
= 7200 m
