Mass NEVER changes

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Acceleration of bike is 0.5 m/s²

Force used in push = 7 N

Mass of bike = 14 kg

Acceleration of bike

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

the size of planets effects the amount of gravitational force each planet has, like jupiter, it has the most gravity.

Answer:

13.75

Explanation:

Density is equal to mass divided by volume. 110/8 = 13.75

Answer:

yes

Explanation:

yes because the molar mass is an intensive property of the substance, that does not depend on the size of the sample. In the International System of Units (SI), the base unit of molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.

Answer:

Yes, if your calculating from grams to moles.

Answer:The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.

Characteristics of Sedimentary Rocks. ● The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral.

Chemical energy in food

As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created. The energy produced from this reaction keeps us warm, helps us move, and allows us to grow. Different foods store different amounts of energy.

Noble gas located in the region D

Noble gas are located in group 18 in the periodic table consisting of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), have a stable electron configuration where the valence electrons are 8(full outer shell of electrons), so it is very hard to react because of its stability

If we look at the periodic system of the elements, the noble gases are on the far right, so that in Figure 8 it is located in area D

And the other region :

A : alkali elements(group 1),

B : alkaline earth elements(group 2)

C : halogen elements(group 17)

Answer:

Octahedral

Explanation:

Recall that according to Valence Shell Electron Pair Repulsion Theory(VSEPR) the shape of a molecule is based on the number of electron pairs on the outermost shell of its central atom.

In BrF4^-, the bromine atom is surrounded by 6 electron pairs. Four bond pairs and two lone pairs.  This means a total of six regions of electron density.

According to VSEPR Theory,  BrF4^- has an octahedral electron geometry and its the molecular geometry will be square planar  since it is of the type AX4E2.

An image of the  BrF4^- is attached below.

Osmosis

Explanation:

Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.

Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.

Answer:

657.2 Hz

Explanation:

Answer: D

Explanation: P = W/t

W = F d

When dividing, if you have a large number over a small, you get a large number. We want a small number, so we want the opposite for our P : W/ t formula. We want a small Work and a large time.

Right off the bat, the two with the least time aren't right then.

From there, we can estimate how much work it would take using the W = F d equation. If there is a small distance, there is less work, which is what we want to achieve a small work over large time.

So, the choice with the most time and the least distance should be correct.
