Water doesn't belong on that list.

The gem amethyst gets its purplish color from trace amounts of iron and aluminum within its crystal lattice structure. Amethyst is a variety of quartz, which is a silicon dioxide mineral. The coloration occurs due to the presence of impurities or color centers that interact with light, absorbing certain wavelengths and transmitting others.
In the case of amethyst, the purple color is primarily attributed to the presence of iron impurities (Fe3+) within the crystal lattice of quartz. The iron impurities absorb certain wavelengths of light in the visible spectrum, particularly in the green and yellow regions, leaving behind the purplish hues to be transmitted to our eyes.
The exact shade of purple can vary in amethyst gemstones, ranging from light lilac to deep violet, depending on the concentration of iron impurities and other factors during their formation. Heat treatment or exposure to radiation can also influence the color of amethyst, but the natural variety gets its beauty from the fascinating interplay of these impurities within the crystal structure.

Answer:A- Gamma rays
Explanation:
Gamma rays are most dangerous among all the given rays because it has the highest frequency i.e. high penetrating tendency. They can also pass through bones and teeth and this is the reason for their potential hazard.
They can destroy the living cell, initiate gene mutation and can cause cancer.
But they can also be used for destroying cancer cells.
The mass of the rocket is
kg.
Answers
The mass of the rocket is 2.9 kg.
To calculate the mass of the rocket, you can use Newton's second law of motion, which relates force (F), mass (m), and acceleration (a) as F = ma. In this case, you have the force (44 N) and the acceleration (15.3 m/s²).
Rearrange the formula to solve for mass:
m = F / a
m = 44 N / 15.3 m/s² ≈ 2.9 kg
So, the mass of the rocket is approximately 2.9 kilograms. The mass is rounded to the nearest tenth of a kilogram as specified in the question. This mass represents the amount of matter in the rocket and is a critical factor in determining how the rocket accelerates when subjected to the given force.

Answer:
The mass of this object is
Explanation:
If an object floats, it means by Newton’s second law that the sum of the forces acting on it are equal to zero because it’s at rest, as you can see on the figure below, the only two forces acting on the charged particle are the weight (W) and the electric force (Fe) due the electric field (E), so Newton’s second law in this case is:
(1)
But weight is mass (m) times gravity acceleration (g) and the magnitude of the electric force is the product of the external electric field (E) and the charge of the particle (q), so using that on (1) and solving for m:
