Answer:
Tone is the author's attitude towards the topic. We can identify it by looking at the setting, characters, details, and word choices. By doing so, it will help us find meaning in the story or passage and help us feel more connected to the writing.
Density of an object is computed by dividing its mass by its volume. D = M / V
Solution:
D = 500 g / 2.75 cm3
D = 181.82 g/cm3
Further, density of an object is computed by dividing its mass by its volume. D = M / V
However, since Volume is the missing component in the equation. Mass of an object is divided by its density to get its volume. V = M / D
<span>Volume of Gold nugget = 50 g </span>/<span> 19.3g/cm3 = </span>2.59cm3
<span>Volume of Iron Pyrite nugget = 50 g </span>/ <span>5.0g/cm3 = </span>10cm3

Answer: The correct answer is option D.
Explanation: Super-giant stars are the stars which are greater than Sun. They have a mass hundred time greater than Sun and can be thousand times greater than Sun.
The masses of the stars are represented in Solar masses which is the mass of the Sun.
Mass of Betelgeuse = 20 Solar masses
Mass of Pollux = 1.7 Solar masses
Mass of Sirius = 2.02 Solar masses
Mass of Sun = 1 Solar mass.
As, the mass of Sun is the least from the given stars. Hence, it is least considered as a super-giant.
Answer: Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.
