2. A 2.75 kg sample of a substance occupies a volume of 250.0 cm^3. Find its density in g/cm.

hichkok12 [17]

Answer:

<h3>The answer is 11 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 2.75 kg = 2750 g

volume = 250 cm³

We have

$density = \frac{2750}{250} \\$

We have the final answer as

Hope this helps you

Students in physics class are asked to find the relationship between the length of a pendulum (string with a weight at the botto

Goshia [24]

Answer:

1) $Time \ for \ pendulum \ swing \ left \ and \ right = 2 \times \pi \times \sqrt{\dfrac{Length \ of \ the \ pendulum \ string}{g} }$

2) The dependent variable = The time it takes for one pendulum swing

3) The independent variable = The length of the pendulum string with weight at the bottom

Explanation:

The relationship between the length of the pendulum string and the time it takes for one pendulum swing is giving as follows;

$T = 2 \cdot \pi \cdot \sqrt{\dfrac{L}{g} }$

Where;

T = The period of oscillation = The time to complete one oscillation =Two swings of the pendulum

L = The length of the pendulum

g = The acceleration due to gravity

Therefore, the time it takes for one pendulum swing is directly proportional to the square root of the length of the pendulum

The dependent variable = The time it takes for one pendulum swing

Th independent variable = The length of the pendulum string with weight at the bottom.

The properties of malleability and ductility can all be explained on the basis of metallic bonding.

<h3>What is malleability?</h3>

The term malleability refers to the ability of a metal to be hammered into sheets. It is a very important property of metals that helps in metal work. The images are not shown here hence the question is incomplete.

Ductility refers to the ability of metals to be drawn into sheets. This is the reason why metals can be used to make wires. All these properties are explained on the basis of metallic bonding.
