Make up a short story to explain jays speed and acceleration change throughout his walk. Make sure to address parts A-D

Answers

Answer:

Speed of jays increases first, again increases, decreases and then increases.

Explanation:

The speed of jays increases while moving from rest to point A and no acceleration due to constant speed. From point A to point B, the speed is continues to increase and no acceleration. From point B to point C, the speed of jays decreases and acceleration is produced in the journey due to change of speed and from point C to point D, the speed of jays again increases and acceleration is produced due to increasing the speed.

Answer:

The speed of jay's walk increases first, again increases, then it decreases and then increases due to his acceleration walk during parts A-D.

Which time shows the lowest composition of all green house gases?

Answers

Answer:

1750

Explanation:

Greenhouse gases are those gases that are believed to contribute to the rise in the temperature of the earth by trapping infrared rays close to the surface of the earth.

Prominent among the greenhouse gases are; N2O, methane and CO2.

From the chart, we can see that the lowest sum of concentration of greenhouse gases measured in ppm was obtained in 1750. Thus this period shows the lowest composition of greenhouse gases.

What is the purpose of a buffer?

Answers

The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

Bobby has a toy car that is sitting at rest on the floor. He decides to play with his toy car and pushes it with 3 newtons to the right. Bobby's friend Sam also decides to play with the toy car and pushes it with 6 newtons to the left at the exact same time. Which of the following best describes the resulting motion of the toy car? A It travels to the right at an increasing speed. B It travels to the right at a constant speed. C It travels to the left at an increasing speed. D It travels to the left at a constant speed.

Answers

Answer: D

Explanation:

The car will move to the left because Sam is implying a grater force (3 N < 6 N) but it is traveling at a constant speed because there is still a force being acted upon it. <3

The result of applying forces to a toy car is required.

Option D is correct.

Force applied by Bobby is 3 N to the right

Force applied by Sam is 6 N to the left

Right is taken as positive and left is taken as negative.

m = Mass of toy

a = Acceleration

Net force applied to the toy

[tex]F=3-6\\\Rightarrow F=-3\ \text{N}\\\Rightarrow ma=-3\\\Rightarrow a=\dfrac{-3}{m}[/tex]

So, the toy will move left with a constant acceleration.

Constant acceleration means its speed will be increasing.

So, option D is correct.

What effect does an increase in carbon dioxide (CO 2 ) have on the concentration of hydrogen ions (H^ + ) in the blood?

Answers

Answer:

As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.

How much so you can be dissolved and 50 mL of water at 30 Celsius see chart:)

Answers

Answer:

The correct answer is - 100 grams.

Explanation:

The solubility graph is a very useful tool because it tells you the amount of solute that can be dissolved per 100 mL of water in order to have a saturated solution of potassium nitrate at a given temperature.

In order to find the solubility of the salt at 30 ∘ C , start from the 30 ∘ C

mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the y axis and read off the value that you land on which is 200. However, it is for 100 ml so half the value you read:

200/2 = 100 gram .

So, solubility ≈ 100 g / 50 mL water

So, a saturated solution of solute will hold about 100 g of dissolved solute, that is of dissociated solute, per 50 mL of water at 30 ∘ C .

A gas made up of homonuclear diatomic molecules escapes through a pinhole 3.98 times as fast as oxygen gas. Write the Chemical formula of the gas.

Answers

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

Graham's law:

[tex]\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }[/tex]

Where V is the speed of the gases and m the molar mass of those:

As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)

[tex]3.98 =\sqrt{\frac{32g/mol}{m_A} }[/tex]

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

H₂

How many kJ are needed to heat 300.0 g of ice at -5.00°C into steam at 100.°C?

Answers

Answer:

Q = 63.9 kJ

Explanation:

Given that,

Mass of ice, m = 300 g

We need to find the heat needed to heat the given amount of ice at -5.00°C into steam at 100.°C

The specific heat of ice, c = 2.03 J/g °C

The formula for heat needed is given by :

[tex]Q=mc\Delta T\\\\Q=300\times 2.03\times (100-(-5))\\\\Q=63945\ J\\\\Q=63.9\ kJ[/tex]

So, 63.9 kJ of heat is needed.
