- 1. Justin usually blows his nose using Kleenex tissues. His snot keeps leaking through the tissue. He decided he is going to create an experiment to find out if there is something better. What is his dependent variable? - A. Justin - B. Amount of snot the tissue can hold - C. Amount of tissue - D. Type of tissue

Answers

Answer 1

Answer:

B. Amount of snot the tissue can hold

Explanation:

In this specific scenario, the dependent variable would be the amount of snot the tissue can hold. That is because this is what Justin is trying to measure, which is also dependent on the type of tissue which would be the independent variable in this scenario. The different types of tissues can absorb different amounts of snot and this is what Justin ultimately wants to determine.

For A: the contact I think would be the bookshelf holding it up the non-contact force would be gravity making it so the book would stay where it was put.

For B: the contact force would be the ball being kicked and the non-contact would be the gravity pulling it back to the ground.

For C: A hiker in the woods reading her compass to determine which direction to go The contact would be her holding the compass and moving around the non-contact would be the compass arrow turning every time she moves.

For D: The child on a sled for the contact force would be the person pushing the little kid down the hill the non-contact force would be the gravity that would be keeping the kid going down the hill and gravity stopping the kid at the bottom of the hill.

The ​density of lead is 11.342 g/cm​ 3​ .​ What would be the volume of a ​200.0 g sample of this metal?

Answers

Answer:

The answer is

17.63 mL

Explanation:

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 of lead = 200 g

density = 11.342 g/cm³

It's volume is

[tex]volume = \frac{200}{11.342} \\ = 17.6335743...[/tex]

We have the final answer as

Answers

Answer:

3.45618%

Explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 10.95

Accepted Value: 11.342

Work:

[tex]\frac{10.95-11.342}{11.342} *100[/tex]

[tex]\frac{-0.392}{11.342} *100[/tex] = -3.45618

You cannot have a negative percentage. Therefore the answer is 3.45618%

Answers

Answer:C.) It has one group in which the manipulated variable is tested, and another in which the responding variable is tested

Explanation: hope this helps

The statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested (option C).

What is a controlled experiment?

A controlled experiment is an experiment where one variable is tested at a time and all other variables are kept constant.

An experiment consists of a manipulated or independent variable, which is the variable changed, and a responding or dependent variable, which is the variable measured.

Therefore, statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested.

The chemical symbol for silver oxide, an ionic compound used to make button batteries, is made of silver and
oxygen and has a chemical formula of Ag20.




Answer 2 and 1

Answers

Answer:

2 Silver Ions

1 Oxygen Ion

Explanation:

Edg2021

The chemical symbol for silver oxide is not Ag₂0. The correct chemical formula for silver oxide is Ag₂O.

Silver oxide (Ag₂O) is an ionic compound composed of silver ions (Ag⁺) and oxide ions (O₂⁻). It is commonly used in button batteries as a cathode material. In this compound, two silver ions combine with one oxide ion to form a stable structure.

The chemical formula Ag₂O indicates that there are two silver ions (Ag⁺) and one oxide ion (O₂⁻) in each formula unit of silver oxide. The subscript 2 after Ag indicates that there are two Ag⁺ ions present, while the absence of a subscript after O indicates that there is one O₂⁻ ion.

Hence, the chemical formulae are discussed above.

Round the number 3456.5 to two significant figures.

Answers

Explanation:

35- this is the answer in 2s.f

When rounding a number to two significant figures, we consider the first two most significant digits from the left. In this case, the number is 3456.5. 3456.5 rounded to two significant figures is 3500.

Rounding numbers is a common mathematical process used to simplify or approximate values to a desired level of precision. It involves adjusting a number to a specific decimal place or significant figure.

To round 3456.5 to two significant figures, we look at the first two digits: 34.

The next digit after the second significant digit is 5. Since 5 is greater than or equal to 5, we round up the last significant digit.

Therefore, rounding 3456.5 to two significant figures gives us:

3500

So, 3456.5 rounded to two significant figures is 3500.

As a star uses up its hydrogen supply, it changes from a main sequence star to a -
A.) dwarf
B.) supernova
C.) black hole
D.) giant

Answers

B is the correct answer

As a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.

What is a Star?

A star may be defined as a type of huge celestial body that is generally constructed of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. They are the luminous bodies that are visible in the sky at night.

A giant is a type of star that has utilized its hydrogen supply in its cores and transformed itself into the thermonuclear fusion of hydrogen in the shell that envelops its surroundings.

This creates an outwards force and stimulates fusion that initiates to increase and hence the star can not able to maintain its equilibrium longer.

Therefore, as a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.

Which best represents a particle containing 28 protons, 26 electrons, and 34 neutrons?
A Fe2-
B
54
2+
28N;
C%2Fe2-
DSNi2+

Answers

Answer:

Ni^2+

Explanation:

The following data were obtained from the question:

Proton = 28

Electron = 26

Neutron = 34

Next, we shall determine the atomic number of the element.

Atomic number of an element is simply defined as the number of protons in the atom of an element.

Thus,

Atomic number = proton number

Proton = 28

Atomic number = proton number = 28

Atomic number = 28

Therefore, the element is Nickel since no two elements have the same atomic number.

Finally, we shall determine the charge on the Nickel atom as follow:

Proton = 28

Electron = 26

Charge on atom =

Charge on atom = Proton – Electron

Charge on atom = 28 – 26

Charge on atom = +2

Therefore, we can represent the Particle as Ni^2+

5. An object is a regular, rectangular, solid with dimensions of 2 cm by 3cm by 2cm. It has a mass of 24 g. find its density.

Answers

Answer:

Density, D = 2g/cm^3

Explanation:

Given the following data;

Length = 2cm

Width = 3cm

Height = 2cm

Mass = 24g

Density = ?

Volume of a rectangular solid (V) = Length × Weight × Height

Therefore, V = L× W × H

Substituting the values, we have;

[tex]V = 2 *3 * 2 = 12[/tex]

V = 12cm

Density can be defined as the ratio of mass to volume i.e mass all over volume.

Mathematically, [tex]Density = \frac{Mass}{Volume}[/tex]

[tex]D = \frac{M}{V}[/tex]

Substituting the values, we have;

[tex]D = \frac{24}{12}[/tex]

Density, D = 2g/cm^3

Hence, the density of the rectangular solid is 2g/cm^3.
