What is the mass of an object that has a density of 3.2 g/cm3 and a volume
of 5.5 cm3? (The density of an object has the equation d =m/v.)

The mass of an object is 17.6 grams.

Explanation:

We have,

Density of the object is 3.2 g/cm³.

Volume of the object is 5.5 cm³

It is required to find the mass of the object. The density of the object is given by the mass acting per unit its volume. It is given by :

m is the mass of an object

So, the mass of an object is 17.6 grams.

answer: a. same unit

explanation:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
