Part C Next, you’ll test the hardness of each rock by scratching it with different substances as shown in the chart. The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of rocks and minerals on a scale of 1 to 10. First try to scratch a rock with your fingernail. If you can make a mark on the rock with your fingernail, record the related hardness value from the chart in your table. If a fingernail doesn’t scratch the rock, try to scratch it with the copper penny. If the penny doesn’t scratch the rock, try the wire nail and finally the masonry nail. Enter a hardness value for each rock.

Answer 1

Answer:

Answer + Explanation:

To determine the hardness value of each rock, you need to follow the instructions provided and test the rocks with different substances. Here is a step-by-step guide:

1. Start by scratching the rock with your fingernail. If your fingernail can make a mark on the rock, record the related hardness value from the chart in your table. For example, if your fingernail scratches the rock and the corresponding hardness value in the chart is 2, you would record 2 in your table.

2. If your fingernail doesn't scratch the rock, move on to the next substance, which is a copper penny. Try scratching the rock with the copper penny. If the penny doesn't scratch the rock, move on to the next substance.

3. The next substance to try is a wire nail. Scratch the rock with the wire nail. If the wire nail doesn't scratch the rock, proceed to the last substance.

4. The last substance to try is a masonry nail. Scratch the rock with the masonry nail. If the masonry nail doesn't scratch the rock, record the highest value from the chart in your table.

By following these steps and recording the highest hardness value achieved through the scratching test with each substance, you will be able to determine the hardness value of each rock.

hope this helps

While researching machines and how they work, Tika finds several online sites that discuss how force and distance are related to work done by a machine.How should Tika most likely describe this relationship between force and distance to her study group?

If the input force is less than the output force, then the input distance must be greater than the output distance.
If the input force is greater than the output force, then the input distance must be greater than the output distance.
If the input force is less than the output force, then the input distance must be the same as the output distance.
If the input force is equal to the output force, then the input distance must be greater than the output distance.

Answers

The right answer for the question that is being asked and shown above is that: "If the input force is greater than the output force, then the input distance must be greater than the output distance." Tika most likely describe this relationship between force and distance to her study group is that If the input force is greater than the output force, then the input distance must be greater than the output distance.

Answer:

If the input force is less than the output force, then the input distance must be greater than the output distance.

An electric buzzer is activated, then sealed inside a glass chamber. When all of the air is pumped out of the chamber, how is the sound from the buzzer affected?The sound is silenced.
The wavelength of the sound increases.
The frequency of the sound increases.
The wave speed of the sound increases.

Answers

The answer is that the sound is increased because the sound waves are mechanical waves, this means that they can't travel trough empty space they need a medium to travel.

Answer:

The sound is silenced.

Which occurs during a disequilibrium?

Answers

Disequilibrium occurs when the quantity of supply does not equal the quantity of demand.

The market is experiencing a disequilibrium when the market price is above or below the equilibrium price. Whenever markets experience imbalances—it creates disequilibrium prices, surpluses, and shortages—market forces drive prices toward equilibrium.

A surplus exists when the price is above equilibrium, which encourages sellers to lower their prices to eliminate the surplus.

A shortage will exist at any price below equilibrium, which leads to the price of the good increasing.

For example, imagine the price of dragon repellent is currently $6 per can. People only want to buy 400 cans of dragon repellent, but the sellers are willing to sell 600 cans at that price. This creates a surplus because there are unsold units. Sellers will lower their prices to attract buyers for their unsold cans of dragon repellant.

The red LED consists of a white LED covered with a red filter. What does the red filter do?

Answers

White light is light that's made up of ALL colors.

If you have a source of white light and you want red light,
then you have to REMOVE all the other colors from the
white light somehow.

That's what a red filter does. The dye in the filter has chemicals
that absorb every color of light except red. Then, red light is the
only thing left to come out of the other side.

(If the light going into the filter had no red in it, then the filter
would appear black, because there wouldn't be any light
coming out of it at all.)

Answer:

black is it

A body mass 30 kg is traveling in space at a speed of 10 m/s. Given that the formula for kinetic energyis KE = 0.5 * m * v^2, and m is mass, v is speed

Answers

The kinetic energy of a body with a mass of 30 kg and a speed of 10 m/s is 1500 kg m²/s².

In physics, the kinetic energy of аn object is the form of energy thаt it possesses due to its motion. In the case above, we are given the formula for kinetic energy:

KE = 0.5 * m * v²

where m is mass and v is speed. And we are given m = 30 kg and v = 10 m/s.

To calculate the kinetic energy, we simply plug in the values of m and v into the formula:

KE = 0.5 * 30 kg * (10 m/s)²

Simplifying the equation gives:

KE = 0.5 * 30 kg * 100 m²/s²

KE = 15 kg * 100 m²/s²

KE = 1500 kg m²/s²

Therefore, the kinetic energy of the body is 1500 kg m²/s².

#SPJ11

Answer:

The kinetic energy of a body mass of 30 kg traveling in space at a speed of 10 m/s can be calculated with the formula KE = 0.5 * m * v^2, where m is the mass of the body and v is the speed. In this case, the kinetic energy would be equal to 0.5 * 30 * 10^2 = 1500 Joules.
