What does a straight line represent on a distance vs time graph?

Answers

Answer 1
A straight line on a distance va time graph represents constant speed
Answer 2

Answer:

It represents the relationship between the distance travelled and time spent as constant or at a stop.

Explanation:

This is because as the line progresses, the time increases the distance should change as well my moving up or down, in a linear equation this relationship is constand but if the line is horizontal though, the distance is not changing despite time passing which means it has come to a stop.

Which of these would have lowest kinetic energy
Boiling water
Ice water
Refrigerated water
Water at room temperature

Answers

Answer:

The answer is ice water, since the particles of a solid have very low kinetic energy.

Explanation:

Answer:

Iced water.

Explanation:

It's a solid. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy.

As water freezes, it does so because after thermal energy leaves the particles, the average translational+rotational kinetic energy decreases, but the total average kinetic energy does not... and the temperature does not change either.

Answers

Answer:

Explanation:

Bc I got it right

Answer:

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.

Answers

Answer:

The density of the pebble is 0.483g/mL (rounded), but it's 0.48333333333333 without rounding. Hope this helped! :)

Explanation:

Volume= 6.0mL                                           Density=Mass/Volume

Mass= 2.9g

D=2.9g/6.0mL

D=0.48333333333333g/mL

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+

C. A paramecium is a single-celled organism that lives in ponds. It travels at a rate of 2,000 micrometers per second. What is the speed of the paramecium in meters per hour?

Answers

Answer:

7.2 meters per hour

Explanation:

It is given that,

The speed of a paramecium is 2,000 micrometers per second.

We need to find the speed of the paramecium in meters per hour.

We know that,

[tex]1\ \mu m=10^{-6}\ m[/tex]

and

1 hour = 3600 seconds

[tex]v=2000\ \dfrac{\mu m}{s}\\\\=2000\times \dfrac{10^{-6}\ m}{(\dfrac{1}{3600})\ s}\\\\=7.2\ \text{meters/hour}[/tex]

Hence, the speed of the paramecium is 7.2 meters per hour.

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.

If they do, they must only go down the lab sink drain and be flushed after with water, so that there isn’t a risk of another chemical mixing with it at a later time. For chemicals that cannot be poured down the lab sink, store them in appropriate containers; plastic bottles are preferred over glass for storing hazardous waste when compatibility is not an issue.

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.

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.

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.
