Answer:
2.29g/cm3.
Explanation:
The following data were obtained from the question.
Mass of the oil = 172g
Volume of oil = 75cm3
Density =..?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:
Density = Mass /volume
With the above formula, we can calculate the density of the oil as shown below:
Density = Mass /volume
Density = 172g/75cm3
Density = 2.29g/cm3.
Therefore, the density of the oil is 2.29g/cm3.
1. 6.0 m
force/mass× acceleration is the equation
since the accelaration is unknown you would divide 180 by the mass of 30kg which is 6
2.A
Answer:
hot
Explanation:
cause the room temperature is higher
The karst topography is typically defined as a geographic location characterized by a rugged terrain containing landscapes like underground rivers, fissures, and cracks. It is mainly due to the dissolution of the bedrock due to a much heavier precipitation taking place in the geographic location.
You would have to give it more mechanical energy.
Like, strap a bunch of powerful rockets to one side of the moon, with all of them pointing in the direction that the moon is already moving in its orbit. Then blast away.
NOTE: There aren't enough rockets or rocket fuel on Earth to make a difference, even if you used ALL of them. The mass of the moon is about
<em>73,476,730,900,000,000,000,000 kilograms</em>
(rounded to the nearest hundred trillion kilograms.)
That's a lot.
