Answer:
<em>The density of rock = 3.37 g/cm³</em>
Explanation:
Density: Density can be defined as the ratio of the mass of a body to the volume. The S.I unit of density is kg/m³. It can be expressed mathematically as ,
D = M/V............................................... Equation 1
Where D = density of the body, M = mass of the body, V = volume of the body.
From Archimedes' principle, a body will displace a volume of water equal to its volume.
Therefore, Volume of the object = volume of water displaced
<em>Given: M = 300 g, V = volume of water displace = 89.0 cm³.</em>
<em>Substituting these values into equation 1</em>
<em>D = 300/89</em>
<em>D = 3.37 g/cm³</em>
<em>The density of rock = 3.37 g/cm³</em>
A molecule, would be the correct answer
Answer:
A topographic map is a map that indicates the features of the land's surface, such as mountains, hills, and valleys. This is usually done with wavy lines that represent the curves and elevation of the land.
The car has gravitational potential energy (Eg)
Eg = mgh
Eg = (53kg) (9.81N/kg) (14m)
Eg = 7 279.02 J
Find distance she traveled:
100m -25m = 75m
58 seconds / 2 second intervals = 29
29 x 2.6m = 75.4 meters total.
if the distance wasn’t rounded the statement was False.
Answer: False
