Identify each thermal energy scourge as Conduction (A) Convection (B) Radiation (c)

Percent abundance is the percentage of all the different isotopes of an element and is used to calculate the average atomic mass. For example 99.98% of all Hydrogen in the universe is [tex]^1H[/tex] meaning hydrogen with 1 proton and 0 neutrons while the remaining 0.02% is  [tex]^2H[/tex] meaning that [tex]^1H[/tex] is the most abundant by  percent.

Answer: 1 C4H6O3 + 1 H2O -> 2 C2H4O2

Explanation:

LEFT HAND SIDE:

C= 4

H=8

O= 4

RIGHT HAND SIDE:

C= 2

H= 4

O= 2

You want the left side to be equal to the right side.

We can multiply each atomic element by 2, to get C4H8O4.

Batteries are filled with acidic fluid mostly of sulphuric acid. It have a pH about 0.8. Alkaline batteries are filled with potassium hydroxide or zinc chloride the pH is around 7 and the term battery acid cannot be used here. Thus option A is correct.

pH of a solution is the measure of H+ ion concentration in the solution. It says how acidic or basic the solution is. If the solution has a pH of 7 it is neutral and if its less than 7 it is acidic and a pH of more than 7 is basic.

Battery is an electronic component which converts chemical energy to electrical energy. It consist of an electrolyte and two electrodes. Usually the fluid used in battery is sulphuric acid  and it is called the battery acid.

Nowadays battery acids are replacing by alkaline fluids which are less hazardous than the acids. Most commonly potassium hydroxide, zinc chloride etc. are used as alkaline fluids.

The electrodes used in batteries are commonly zinc and magnesium. Thus, the pH of battery acid about 0.8 and option A is correct.

Mitochondria - energy production in plant and animal tissue

Explanation:

The mitochondria is the power house of a cell. it contains adenosine-tri- phosphate or ATP molecules that produce energy through active transport. The mitochondria is responsible for energy production in both plant and animal cells

The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.

Mass Number (A) = Number of protons + Number of Neutrons

Atomic Number (Z) = Mass Number (A) - Number of Neutrons

Atomic number = number of protons = number of electrons  ⇒ neutral atoms

Atomic number - positive charge = number of electrons ⇒ cation

Atomic number + negative charge = number of electrons ⇒ anion

Answer:

The correct option is A: "He is trying to increase his accuracy but not his precision"

Explanation:

Accuracy of measurement is when the value of the measurement is close to the actual value of that measurement while precision is when the experiment is repeated using the same instrument but obtaining different values.

When Boyd changed the weighing balance in his experiment to a smaller one, the smaller weighing balance has better accuracy (smaller graduations) than the initially used one because the smaller weighing balance will provide a value close to the actual value of the mass of the product. If he had, however, repeated the experiment without changing the weighing balance, he would have sought to increase his precision.

From the description above, it can be said that Boyd was trying to increase his accuracy but not his precision

Answer:

The correct option is A: "He is trying to increase his accuracy but not his precision"

Carbon tetrachloride, also known by many other names (such as tetrachloromethane, also recognised by the IUPAC, carbon tet in the cleaning industry, Halon-104 in firefighting, and Refrigerant-10 in HVACR) is an organic compound with the chemical formula CCl4.

Answer:

A

Explanation:

Animals take in oxygen and convert it into carbon dioxide therefore the oxygen levels will decrease and the carbon dioxide levels will increase

If an animal is placed into a sealed container for a short time, the oxygen level will:  decrease and the carbon dioxide level will increase.

The oxygen held inside the space is quickly being consumed by the freight or because of rusting inside a space, and that encased spaces must consistently be treated as perilous. And the carbon dioxide levels on the other hand will increase.

It will not take a long time for an animal to survive under these conditions.

Thus. option A is correct.

Explanation:

Earth is our home and it is in the solar system.

Earth is the fifth-largest of the planets in the solar system and the third planet from the sun. Earth is the only planet having oxygen and water that supports life. Till now according to the research Earth is the only planet having life.

Planets are in the solar system, the solar system is in the milky way and the milky way is present in the universe. The astronomer identifies our home in the universe as "Earth is in the solar system" as Earth is our home.

Hence, the correct answer is "Earth is in the solar system."

Answer:

The Milky Way is in the universe. The solar system is in the Milky Way. Earth is in the solar system.

Explanation:

If the Milky Way Is in the universe and solar system you would know earth is also In the solar system, so "Our home planet is the third planet from the Sun, and the only place we know of so far that's inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface."

V = 21.2 cm³

Explanation:

Given data:

Diameter of block = 3.0 cm

Volume of block = ?

Solution:

Formula:

V = 2πr³

First of all we will calculate the radius from diameter.

r = d/2

r = 3.0 cm/2

r = 1.5cm

V = 2(22/7) (1.5cm)³

V = 2(3.14) (3.375cm³)

V = 21.2 cm³

Winds are a result of the tendency of warm air to rise and, conversely, cool air to sink. ... Because the atmosphere constantly flows, like a fluid in a container, air rushes into such low pressure areas from cooler, high-pressure ones, and the movement of the air creates wind.
