A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3

miskamm [114]

Answer:

The answer is

Explanation:

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

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

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

$density = \frac{4240}{1564} \\ = 2.710997442...$

We have the final answer as

Hope this helps you

A gamma ray photon has an energy of 4.75 x 10-14 joules. What is the frequency of this radiation?

Rama09 [41]

The frequency of the radiation is equal to $7.17 \times 10^{19}$ Hertz.

<u>Given the following data:</u>

Photon energy = $4.75 \times 10^{-14}$ Joules

To find the frequency of this radiation, we would use the Planck-Einstein equation.

Mathematically, the Planck-Einstein relation is given by the formula:

$E = hf$

<u>Where:</u>

h is Planck constant.

f is photon frequency.

Substituting the given parameters into the formula, we have;

$4.75 \times 10^{-14} = 6.626 \times 10^{-34} \times F\\\\F = \frac{4.75 \times 10^{-14}}{6.626 \times 10^{-34}}$

Frequency, F = $7.17 \times 10^{19}$ Hertz

Identify all the physical properties of a base.

KiRa [710]

Answer:

Bases are ionic compounds that produce negative hydrogen ions (OH⁻) when dissolved in water.
An example of a base is Sodium Hydroxide (NaOH).
Bases have a bitter taste.
Bases feel slippery.
Bases conduct electricity when dissolved in water.
Bases change litmus paper from red to blue in colour.
They react with acids to form a salt and water, this process is called neutralisation.
The pH of bases ranges from 8-14.
Turns phenolphthalein pink.
