From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.
Theoretical frame:
Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.
Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.
The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.
There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.
According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,
Graphite ⇒ 1 - 2Talc ⇒ 1Gypsum ⇒ 1.5 - 2Calcite ⇒ 3Fluorite ⇒ 4Apatite ⇒ 5 Magnetite ⇒ 5 - 6.5Pyrithe ⇒ 6Feldespat ⇒ 6 - 6.5Quartz ⇒ 7Link to a related question:

What is the frequency of a wave that has a wavelength of .20 m and a speed of 22 m/s
Answers
Answer:
110 Hz
Explanation:
Find the frequency of the wave using the formula, frequency = speed / wavelength.
Plug in the speed and wavelength, and solve:
frequency = speed / wavelength
frequency = 22 / 0.2
frequency = 110
So, the frequency of the wave is 110 Hz

A ) Fossil fuels provide cheaper energy
MARK AS BRAINLIST IF IT IS USEFUL .
Fossil fuels are a non-renewable resource that takes years to form. They are the source of large energy production and provide cost-efficient cheaper energy. Thus, option A is correct.
What are fossil fuels?Fossil fuels are the dead remains that got converted into sediments and over millions of years produced the fuels used to drive energy. They are produced from deposition of the organic matter and are widely used resources for energy.
They are present in the crust of the earth and are a cheaper form of energy than wind and geothermal energy. They are found in the form of coal, petrol, diesel, and other natural gases. They are produced from decaying organic matter.
These fuels are less costly than the alternative form of energy, however, are the reason for increased temperature and climate change. They have added to the greenhouse gases and are major pollutants.
Therefore, option A. fossil fuels are cheaper.

What are similarities and differences between insects that go through complete metamorphosis and incomplete metamorphosis?
Answers
There are two types of metamorphosis-incomplete and complete.
In incomplete metamorphosis, an adult insect lays an egg. The egg hatches into a nymph, which is like a mini adult. This nymph then grows into an adult. As the nymph grows, it molts several times. Grasshoppers are examples of insects that undergo incomplete metamorphosis.
