Why does Mercury have almost no atmosphere?
Mercury spins on its axis too fast to have an atmosphere.
Radiation from the Sun blows the atmospheric particles off into space.
Mercury's gravity is too weak to hold an atmosphere.
Mercury orbits the Sun at such high speed that the atmosphere is blown away.

Answers

Answer 1

Answer:

There are two main reasons. First, Mercury is small and doesn't have much gravity so it's hard to hold onto an atmosphere. Second, Mercury is close to the Sun so any atmosphere gets blasted away by stuff being blown off the Sun.

Explanation:

Because Mercury has no atmosphere, it can't hold onto its heat very well. The night side of Mercury gets very cold, which brings down the average temperature of the planet and makes it only the second hottest planet in the Solar System after Venus.

Answers

Answer:

The fact that hot air rises and cold air sinks.... Because Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.

Answer:

It is the first option

Why?

Because hot air rises and cold air rushes to land which causes wind. This type of wind is called land breeze. The thing is that lower the pressure, higher the wind speed

This is why you see with a barometer in storms that the air is in low pressure.

(there are 3 quetions) how is heat being transfered in:
1. conduction
2.convection
3.radiation
Please answer as soon a possible

Answers

Answer:3

Explanation: if I was like a rated wave

conduction is when heat is transferred through physical touch
eg: when you touch a hot pan, the heat is physically transferred from the pan to your hand.
convection is when the heat is transferred through liquids
eg: when you mix hot water and lukewarm water, they both mix and come to the middle.
radiation is where heat is transferred through the air (or basically not through touch)
eg: how the sun’s light reaches our earth.

Write 5 original weather proverbs and explain why they are true.

Answers

“Red sky at night, sailors delight. Red sky in morning, sailors take warning.”
A reddish sunset means that the air is dusty and dry. Since weather in North American latitudes usually moves from west to east, a red sky at sunset means dry weather—good for sailing—is moving east. Conversely, a reddish sunrise means that dry air from the west has already passed over us on their way easy, clearing the way for a storm to move in.

“Clear Moon, frost soon.”
When the night sky is clear, Earth’s surface cools rapidly—there is no cloud cover to keep the heat in. If the night is clear enough to see the Moon and the temperature drops enough, frost will form. Expect a chilly morning!

“Ring around the moon? Rain real soon.”
A ring around the moon usually indicates an advancing warm front, which means precipitation. Under those conditions, high, thin clouds get lower and thicker as they pass over the moon. Ice crystals are reflected by the moon’s light, causing a halo to appear.

“Rain foretold, long last. Short notice, soon will pass.”
If you find yourself toting an umbrella around for days “just in case,” rain will stick around for several hours when it finally comes. The gray overcast dominating the horizon means a large area is affected. Conversely, if you get caught in a surprise shower, it’s likely to be short-lived.

“The higher the clouds, the finer the weather.”
If you spot wispy, thin clouds up where jet airplanes fly, expect a spell of pleasant weather.

Keep an eye, however, on the smaller puff clouds (cumulus), especially if it’s in the morning or early afternoon. If the rounded tops of these clouds, which have flat bases, grow higher than the one cloud’s width, then there’s a chance of a thunderstorm forming.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend, Sandy, told him that he should try using Clean-O detergent, a new brand of laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants three times each, the pants washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water. 1) What was the problem SpongeBob wanted to investigate? 2) What was the problem SpongeBob wanted to investigate? 3) What is the dependent variable? 4) What should be SpongeBob’s conclusion?

All chemicals in the lab (including foodstuffs and store-bought chemicals) should be treated as if they could be hazardous. True or False?

Answers

Answer: True, all chemicals should be treated as if you don’t know what they are.

Explanation:

All chemicals should be treated as if you do not know what they are. In this way you can protect yourself and others from potential hazards, as chemicals can be mixed up or confused.

The statement "All chemicals in the lab (including foodstuffs and store-bought chemicals) should be treated as if they could be hazardous" is definitely true.

What are Chemicals?

Chemicals may be characterized as any sort of basic substance that is significantly utilized in or manufactured during a reaction that involves remarkable alterations to atoms or molecules.

The methodology of treating chemicals demonstrates their physical as well as chemical properties, appearances, and reactiveness. In this way, one must become much more confidential with all the basic characteristics, potential hazards, and efficiency of any chemical.

This procedure also delivers proficiency to you in the future with respect to chemicals or their efficiency. It also decreases your potential fear of chemicals.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
