Answer: Well there is a simple solution which is death..
The volume of a substance can directly be calculated by
the ratio of mass and density. That is:
volume = mass / density
Since the mass is 4.5 kg or 4500 grams, therefore:
volume = 4500 g / (8.89 g / cm^3)
<span>volume = 506.19 cm^3</span>
Answer: 2.9kg
let mass be=m ; F=15N; Sin(theta)=32°;g =9.8kgm/s^2.
represent the mass. By resolving forces, we have:
F=mgSin(theta)
15N=mgSin(32°)
m=15N/g×Sin(32°)
m=15N/9.8m/s^2÷Sin(32°)
=2.888kg2.888
≈2.9kg
