A box with a mass of 3.5 kg is pushed along a table. If the net force on the box is 35 Newtons, what is the acceleration of the box?
PLLSS HELP ME
Answer:
10 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
m is the mass
f is the force
From the question
mass = 3.5 kg
force = 35 N
We have
[tex]a = \frac{35}{3.5} \\ = 10[/tex]
We have the final answer as
10 m/s²Hope this helps you

Which non-destructive technique is used for analyzing carpet fibers at a crime scene?
______________ is a non-destructive technique used for analyzing carpet fibers at a crime scene and preserving evidence in the original form.
( forensic science question)
Room temperature fluorescence spectroscopy is a non-destructive technique used for analyzing carpet fibers at a crime scene and preserving evidence in the original form.
In investigations, it is often necessary to preserve the physical integrity of evidence so that it can be presented in court. It therefore becomes important to use methods of analysis that are non - destructive when analyzing the material.
One of the most useful non - destructive methods of analysis is room temperature fluorescence spectroscopy. This method of analysis is accurate, yet preserves the physical integrity of evidence.

Can we change the ratio between the elements?
Answer:A compound is a combination or two or more elements held together by chemical bonds. Compounds can only be separated by chemical processes. Since chemicals are composed of different elements, determining the ratio between the elements can allow you to analyze how much of each compound is present. Such a process is also useful for analyzing chemical reactions that are being performed in chemistry experiments. Making connections between units and how elements combine to form compounds can help you to better understand their ratios.Hydrogen peroxide,H2 O2. There are 2 moles of hydrogen and 2 moles of oxygen giving us a ratio of 2:2. We can reduce this ratio by dividing both numbers by a factor of both of them.

why is water able to easily dissolve ionic compounds
Answer:
Water is a covalently bonded molecule. H2O-> Oxygen and hydrogen are both nonmetals. Ionic compounds are made up of a nometal and metal which causes it to have electrical components. A covalent bond is stronger than an ionic bond, which allows water to break down ionic salts.

Which describes a molecule? (Select all that apply.)
It can be two or more of the same elements combined together.
It can be one element by itself.
It can be two or more different elements combined.
It can be the combination of different neutrons.
Answer:
a) It can be two or more of the same elements combined together.
A molecule is two or more atoms of the same element chemically combined.
Example is an oxygen molecule.
Molecules can be described as two or more of the same or different elements combined together. Therefore, options (A) and (C) are correct.
What is a molecule?A molecule can be described as a combination of two or more atoms that form the smallest unit into which the structure and chemical properties of that substance can be classified and preserved by a pure substance.
A molecule may be homonuclear if it consists of atoms of a single chemical element such as oxygen molecule (O₂) or it may be heteronuclear such as water (H₂O).
A molecule consists of an arrangement of atoms held together by the forces of valence. Two atoms that are chemically combined comprise diatomic molecules.
Heteronuclear diatomic molecules consist of two combined atoms of the same substance such as Carbon monoxide (CO), hydrochloric acid (HCl), etc.
Therefore, a molecule can consist of atoms of the same or different elements.

A quantity of gas has a volume of 2250 at a temperature of 45 C and a pressure of 650 torrWhat is the temperature (in °C) if the volume remains unchanged but the pressure is decreased to 565 torr?
Answer:
your answer is 769
Explanation:
i took the test lol
The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.
The temperature at 565 torr = 276.5 K
What are gas laws?Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant.Boyle's Law states that when the temperature and mass are both constant, the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure.Charles' law states that if the pressure remains constant, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature.The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.Avogadro's law states that equal volumes of different gases contain an equal number of molecules under the same temperature and pressure conditions.
The temperature = [tex]\frac{565 X 318.15}{650}[/tex] =276.5 K

2. You are given a mixture of sand, salt, metal filings and small stones. What would you do to separate all four items?
I’ll give brainliest, thanks, 5 stars to the best answer that has been explained properly
Answer: Well, I'd personally go with the tedious route and pick them all out by hand, but I know what doesn't really help. Just a suggestion though, sorry.
Explanation: Don't listen to my advice if you want any free time.
Answer:
Start by using a magnet to separate out the metal fillings.
Then put the mixture through a sieve to separate out the stones.
Then mix it into water and drain out the sand.
Finally, boil the water off to get the salt back.
Explanation:
The metal fillings should be magnetic, and so a magnet will attract only the metal and allow you to remove it.
Putting the mixture through a sieve will basically sift it, since the sand and salt will fall through the holes but the rocks will be too big.
Mixing the mixture into water will dissolve the salt but not the sand, allowing you to pour off the water and be left with sand.
Boiling the water will cause the H2O to become a vapor, while leaving the salt behind.
