Help on a science question from 6th grade

This is probably something you learned in elementary school: Rivers almost never flow in a straight line. Instead, they twist and turn along serpentine paths

Hello!

[tex]\large\boxed{a = 3m/s^{2}}[/tex]

Use the following equation to solve for the average acceleration of the motorcycle:

[tex]a = \frac{v_{f}-v_{i}}{t}[/tex]

Plug in the given final, initial velocities, and the time:

[tex]a = \frac{15-6}{3}\\\\a = \frac{9}{3}\\\\a = 3m/s^{2}[/tex]

I would say try hinting it to her, not in an obvious way but kind of flirt. Make sure to be yourself!

Answer: This is the magic element for everything on Earth. All life on Earth depends on carbon (C). It is in nearly every biological compound that makes up our bodies, systems, organs, cells, and organelles. When you breathe out, there is a lot of carbon dioxide (CO2).

Explanation:

Answer:

Like Carbon dioxide? or just like carbon? well anyway we breath in oxygen and breath out carbon the carbon goes into the air and gets re-cleaned turned into oxygen again. And also thousands of cars that run everyday going places let out tons of carbon into the the air every minute. (aka which is bad for human society, considering there's probably more carbon in the air then there is oxygen.)

Explanation:

So yes carbon does apply in everyday life. By the way the other person is right too. :)

THe answer on EDG

Answer:

B

Explanation:

EDGE 2021

Answer:

Known as the "king of the jungle" or the "king of beasts," lions are at the top of the food chain, and they hunt and eat other animals to survive. Their niche in the ecosystem allows them to help with other animal population control and prevent the spread of disease.

Explanation:

thats very nice lol, things stuck in amber are very cool

Answer:

compaction and cementation

Explanation:

sedimentary rock is layered rock, in order to become sedimentary it most be compacted to form layers and cemented to become hard. This is what i think. Hope i can help :)

Answer:

C

Explanation

His greatest contribution is the atomic model

Answer:

f=ma

40=m*8

m=5kg

another object of same mass is added

=>m=5+5=10kg

f=10*8=80N

Explanation:

Answer:

The sugar particles are so small that they have dissolved in the water, and can easily pass through the filter.

Answer:

Sugar can not be separated due it has very fine particles.

Explanation:

When we use to separate sugar with salt they both are dissolved with the water.

Answer:

1-water 2-Sun 3-Gravity

Answer: Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. hope this helps

Explanation:

When a dominant trait is present it will always show. For example long tails are dominant. (Ll and LL will both result in long tails). For recessive traits you need two of them for the trait to show. For example short tails are recessive. (You HAVE to get ll for the short tail trait to show in the offspring.

Answer: Molar mass of [tex]NH_3[/tex] is 17.03 g

Explanation:

Molar mass is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

It is found by adding the atomic masses of all the elements present.

Atomic Mass of Nitrogen (N) = 14.007 g

Atomic Mass of Hydrogen (H) = 1.008 g

Molar mass of [tex]NH_3[/tex] = 1(14.007)+3(1.008) g = 17.03 g

Answer:

how has your day been if it's night or the middle of the day

Explanation:

tell me and i hope u have a better or even better day tomorrow

Answer:

the answer is True

Explanation:

the answer is True

Answer:

The correct answer is - ligands such as hormones and neurotransmitters.

Explanation:

Communications between the cells of the unicellular organisms take place by the chemical signaling and the substances that help in sending chemical signals between cells are called ligands.

A ligand is a chemical molecule that binds with a specific molecule or a specific signaling receptor, a protein in or on the target cell. Hormones and neurotransmitters are the ligands that help in cell signaling and send chemical messages to the target sites.

Answer:

false

Explanation:

not all science is good, or has good effects

False.

Science can possibly be dangerous when used by the wrong people. It can be used to create bombs, bioweapons, and much more.

Answer:

2.108x10²³ atoms

Explanation:

In order to convert from moles (of any substance) to atoms (or molecules), we need to use Avogadro's number: It is the number of units in one mol.

In one mol there are  6.023x10²³ atoms.

0.35 mol * 6.023x10²³ atoms/mol = 2.108x10²³ atoms

Thus, in 0.35 moles of carbon there are 2.108x10²³ atoms.

Answer:

A. Water

Explanation:

Virtually every known substance can be referred to as MATTER, as long as it has weight and occupies space. Matter can exists in three different forms namely: solid, liquid and gaseous states.

However, each state of matter has its own unique property that characterizes it. WATER is the only matter that can exists in the three different states as follows:

- LIQUID - WATER

- SOLID - ICE

- GASEOUS - STEAM OR VAPOUR.

Answer:

2. About 138 g of KI will dissolve in 100 g of water at 10°C

3. 34.5 g of KI will dissolve in 25 g of water

4. The solution is not saturated but is unsaturated

Explanation:

From the graph:

1. KI is more soluble than KCl at 10°C because approximately 138g of KI dissolves at 10°C compared to 30 g of KCl per 100 g of water

2. About 138 g of KI will dissolve in 100 g of water at 10°C

3. 138 g of KI dissolves in 100 g of water at 10°C

In 25 g of water which is 1/4 × 100 g of water, 138/4 g = 34.5 g of KI will dissolve

Therefore, 34.5 g of KI will dissolve in 25 g of water

4.At 20 °C, a saturated solution of NaNO₃ will contain about 88 g of NaNO₃ in 100 g of water.

The solution prepared by the chemist contains 45 g of NaNO₃ in 100 g of water at 20 °C. The amount of solute present in the solution is less thanthe solvent can dissolve at that temperature, therefore, the solution is not saturated.

Answer:

Antimony

Explanation:

Number of moles = 9.51 mol

Mass= 1157.9376 g

The identity of an element is obtained from it's Molar mass.

This is given by the equation;

Molar mass = Mass / Number of moles

Molar mass = 1157.9376 g / 9.51 mol

Molar mass = 121.76

The only element with molar mass of 121.76 is Antimony
