What is the formula for calculating density?

Density can be determined by the mass of an object and how much it takes up space (volume). It is represented by the formula D = M/V where D is the density in kg/m^3 or lb/ft^3, M is the mass in kg or lb and V is the volume in m^3 or ft^3. The answer would be A. For example, you are given the mass of an object of 40.5kg and a volume of 15m^3. Find its density.

D = M/V
D = (40.5 kg) / (15 m^3)
D = 27/10 or 2.7 kg/m^3

Answer:

My answer is A.

Explanation:

by using a density triangle, you would have to cover up the density and then it will show you, m over v. so that means you would have to divide.

WILL MARK BRAINLIEST Why do we see sedimentary rocks more often than igneous and metamorphic rocks?

Arisa [49]

Answer:

because they are the rocks that line the surface of our planet

Explanation:

We see sedimentary rocks more than other rock types because they are the rocks that line the surface of our planet.

Sedimentary rocks typically form the earth cover due to the way they are formed.

These rocks are produced by the weathering, transportation and deposition of sediments within a basin.
In this basin, the sediment is lithified and converted to sedimentary rocks.
These processes are driven by the external heat engine
Therefore, it is confined to the surface.
Igneous and metamorphic rock's processes are confined to the subsurface.

A student who was training for a cross country race jogged for 2. 0 hours and covered a distance of 14. 0 kilometers. What was t

FinnZ [79.3K]

The average speed is 116.66m/s.

Given - The path traced is 14km , time for jogging is 2 hrs=120min

To find the average speed-

Speed refers to the ease of the movement and degree of mobility as a result of force application.
Due to this there is involvement of velocity.
Journey of average speed is the cumulative of distances and time.
Kinetic theory refers to the Boltzmann constant connecting to the standards of distance traversed.

calculations-

$Speed= \frac{Distance}{Time}$
