What is the density of a substance of volume 3 m3and mass 9 kg?

Physics
1 answer:
butalik [34]3 years ago
7 0

Answer:

Density = 3 kg/m³

Explanation:

Given the following data;

Volume = 3m³

Mass = 9 kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Density = \frac{mass}{volume}

Substituting into the formula, we have;

Density = \frac{9}{3}

Density = 3 kg/m³

Which of the following are vector quantities? Select all that apply.
valkas [14]

Answer:

7 miles southwest

9 steps to the left

75 mph north

Explanation:

A vector quantity is any physical quantity that specifies the magnitude of the quantity and its direction.

So, the choices that gives a magnitude and direction are vectors.

The other type of physical quantities are the scalar which only specifies the magnitude but no direction;

9 steps to the left and  7 miles southwest are called displacement

75 mph north is velocity

A ray diagram without the produced image is shown.
4vir4ik [10]

A car acting as an object in front of a biconvex lens between F and 2 F on the object side of the lens. There is a light ray parallel to the principal axis that is bent through F on the image side of the lens. There is a ray straight through the center of the lens. The rays intersect below the x axis further than 2 F away from the lens and farther from the principal axis than the object is tall.

<u> The image produced by the lens is (b) inverted and real</u>

Explanation:

A real image occurs where the rays converge.

Real images can be produced both by the  concave mirrors or  converging lenses, but the condition is that the object of consideration is always  placed far  away from the mirror or the lens than the focal point, and thus the  real image produced is inverted.

Examples of structure or machine parts that may fail due to bending​
Alex_Xolod [135]

Answer:

<em>Structural failure is initiated when a material is stressed beyond its strength limit, causing fracture or excessive deformations; one limit state that must be accounted for in structural design is ultimate failure strength.</em><em><u>Compressive, tensile, bending and buckling are the basic types of structural failure for construction elements. These are caused due to faults in design and construction</u></em>

The complexity and variety of organic molecules is due to
Anastaziya [24]

Answer:

Due to the chemical versatility of carbon atoms

Explanation:

Carbon is a very important element and it is commonly found in many varieties of chemical compounds. They are also found to be present in space in various amount. It is often considered to be versatile because they are capable of forming single, double, as well as triple bonds. This enables them to make single and branched chains. They also form ring chains when combined with other atoms of carbon.

It is because of this versatility of carbon atoms, there forms complex variety of organic molecules.
