Answer:
To convert among units in the metric system, identify the unit that you have, the unit that you want to convert to, and then count the number of units between them. If you are going from a larger unit to a smaller unit, you multiply by 10 successively. If you are going from a smaller unit to a larger unit, you divide by 10 successively

Mr. Bullis wants to know if he gives teachers candy, it will make them smile more. He gives half the teachers candy and the other half get nothing. He then records the number of times the teachers smiled.
Experimental Group:
Control Group:
Answer:
the experimental group would be the teachers who recieved the candy
control group would be the teachers who dont get any candy
Explanation:
experimental group is the group that receives the test variable being tested in this case the variable being the candy
and the control group is the group who doesn't receive the variable
purpose of having a control is to rule out other factors which may influence the results of an experiment.
If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume
Answer:
The answer is 200 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density}\\[/tex]
From the question
mass = 150 g
density = 0.75 g/cm³
We have
[tex]volume = \frac{150}{0.75} \\ [/tex]
We have the final answer as
200 cm³Hope this helps you

Which of the models best represents CaCO3?
Answer: B
Explanation:
To solve this we must be knowing each and every concept related to CaCO[tex]_3[/tex]. Therefore, the correct option is option B among all the given options.
What is CaCO[tex]_3[/tex]?Carbonate of calcium One of the best-known compounds is CaCO[tex]_3[/tex]. Calcium carbonate is indeed a non-toxic, odorless substance. CaCO[tex]_3[/tex] is a white mineral found naturally in chalks, limestones, and marbles. It is a common material found in rocks as calcite and aragonite.
CaCO[tex]_3[/tex] is most commonly found in limestone. It is a sedimentary rock composed primarily of calcite and is the primary component of eggshells, snail shells, seashells, and pearls. Calcium carbonate is also used in medicine as a source of calcium or as an antacid. Although excessive calcium carbonate ingestion is dangerous and causes poor digestion.
Therefore, the correct option is option B.

The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .
Answer: the 1st answer is neutrons and i think the 2nd is nucleus
Explanation:
The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.
What is atomic mass?The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.
The atomic mass of an element = No. of protons + No. of neutrons
or
The atomic mass of an element = No. of electrons + No. of neutrons
The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.
As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.
For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s
Answer:
The answer is option DExplanation:
To find the speed given the kinetic energy and mass we use the formula
[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]
where
m is the mass
v is the speed
From the question
KE = 15 J
m = 2.3 kg
We have
[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]
We have the final answer as
