Where on Earth's surface might you be if you are experiencing the trade winds? Explain how air pressure, temperature, and the Coriolis effect in movement and direction of thesewinds.
""The polar easterlies"-is dry and cold prevailing winds that blow from the high pressure areas of the polar highs at the north and south poles towards low pressure areas within the Westerlies at high latitudes.
Cold air diminish at the pole making the high force, Pushing an equator-ward discharge, of air; that outflow is then Sidetrack westward by the Coriolis effect."

If the diameter of the black marble is 3.0 cm, and by using the formula for volume, what is a good approximation of its volume? Record to the ones place
Answer:
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

How can changes in temperature cause movement of air and other fluids on Earth? , “information I found on the Internet”
Answer:
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.

Arkeisha and Rodney are having a discussion about the correct use of the term "battery acid." Arkeisha insists that an alkaline battery does not have an actual acid contained within it, but Rodney disagrees and says that all batteries have acid in them. Which student is correct? A. Arkeisha is correct because the fluid in an alkaline battery has a pH between 0.0 and 6.9. B. Arkeisha is correct because the fluid in an alkaline battery has a pH between 7.1 and 14.0. C. Rodney is correct because the fluid in all batteries has a pH between 0.0 and 6.9, including alkaline batteries. D. Rodney is correct because the fluid in all batteries has a pH between 7.1 and 14.0, including alkaline batteries.
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.
What is pH?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.

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

What is the specific heat of a metal if the temperature of a 12.5 g sample increases from 19.5 C to 33.6 C when it absorbs 37.7 J of heat.
Answer:
0.213 J/g°C
Explanation:
To calculate specific heat of the metal, the formula is used:
Q = m × c × ∆T
Where Q = amount of heat
m = mass
c = specific heat
∆T = change in temperature
According to this question, Q = 37.7 J, m= 12.5 g, initial temperature= 19.5 °C, final temperature = 33.6°C, c=?
Q = m × c × ∆T
37.7 = 12.5 × c × (33.6-19.5)
37.7 = 12.5c × 14.1
37.7 = 176.25c
c = 37.7/176.25
c = 0.2139
Hence, the specific heat of the metal is 0.213 J/g°C

can you help me with percent abundance??
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.

How would an astronomer identify our home in the universe? Earth is in the solar system. The Milky Way is in the solar system. The solar system is next to the Milky Way. Earth is in the Milky Way and next to the solar system. The Milky Way is in the universe. The solar system is in the Milky Way. Earth is in the solar system. The universe is in the Milky Way. The Earth is in the Milky Way. Earth is at the center of the solar system.
Answer:
Earth is in the solar system.
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."

Boyd takes additional measurements of the mass of product formed in a reaction. He uses a balance that has smaller graduations than the first balance he used.
What is Boyd most likely trying to change?
Options:
He is trying to increase his accuracy but not his precision.
He is trying to increase his precision but not his accuracy.
He is trying to decrease his precision and increase his accuracy.
He is trying to increase his precision and decrease his accuracy.
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"
