Answer:
A phase change is occuring; the liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces.

What is the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet?
0.3
3
6
27
Answer:
it would be 3
Explanation:
because you have to divide the length by the height of the incline.
The mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.
What is the mechanical advantage?Mechanical advantage is a measure of the ratio of output force to input force in the system, it is used to obtain the efficiency of a mechanism.
The formula for the mechanical advantage of the inclined plane is found as;
[tex]\rm Mechanical \ advantage = \frac{length}{height} \\\\ Mechanical \ advantage =\frac{9}{3} \\\\ Mechanical \ advantage =3[/tex]
Hence the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

It is closer to the center of the Earth.
More people live here.
There is a lot of plate movement)
HELP ME PLS AM IN A TEST I BEG YOU PLS
Answer:
Many volcanoes in the Ring of Fire were created through a process of subduction. And most of the planet's subduction zones happen to be located in the Ring of Fire. Subduction happens when tectonic plates shift, and one plate is shoved under another.

How is sleet different from hail?
Answer:
Hail occurs in warm weather, while sleet occurs during cold weather. When the temperature falls below 32 degrees, precipitation falls out of a cloud as snow. ... Unlike hail, sleet is tiny in size and falls only once from the sky.

A collector of rare items is negotiating with a museum. He wants to sell a spear he claims to have been
used to kill a mammoth over 11,000 years ago. A spear that size would have started with around 4g of
Carbon-14, and the museum tests show it now contains around 2g. How many half-lives have passed since the spear was carved?
Answer:
I'm not sure if you maybe forgot to add in some information but I can give you the equation you will need to solve this..! (just without the bit of infomration you might need)
[tex]2=4(\frac{1}{2})^{\frac{1100}{t}}[/tex]
In this case you'll be solving for t and I can help you with your first step, you'll divide 2 by 4, getting you to:
[tex]\frac{1}{2} =\frac{1}{2}^{\frac{1100}{t}[/tex]
Answer:
1 as 2g is half of 4g
Explanation: that means that the spear is closer to 6k years old
A negative charge of -3.0 x 10^-5 C is placed 0.35 m from a positive charge of 9.0 x 10^-5 C. What is the force between the two charges
Answer:
the force between the two charges is 198.37 N
Explanation:
Given;
charge of the first particle, Q₁ = -3 x 10⁻⁵ C
charge of the second particle, Q₂ = 9.0 x 10⁻⁵ C
distance between the two charges, r = 0.35 m
The force between the two charges is calculated from Coulomb's law;
[tex]F = \frac{kQ_1Q_2}{r^2}[/tex]
where k is Coulomb's constant = 9 x 10⁹ Nm²/C²
[tex]F = \frac{(9\times 10^9)(3.0\times 10^{-5})(9\times10^{-5} )}{0.35^2} \\\\F = 198.37 \ N[/tex]
Therefore, the force between the two charges is 198.37 N

Many people love roller coasters. Some people call them scream machines. They agree that
riding a roller coaster is a thrilling experience. What you may not realize while you are going 60 miles an hour is that a roller coaster has no
engine. You are not being propelled around the track by a motor or pulled by anything. A roller coaster moves on its own. How do you think that
can happen?
Answer:
There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

How does Earth's movement affect how the Sun is seen? The Sun is stationary, but Earth's rotation makes it appear to move east to west across the sky. Earth's rotation around the Sun makes the Sun appear to move across the sky every 365 days. The Sun and Earth move around each other, so the Sun moves east to west across the sky. The Sun is stationary, but Earth's clockwise rotation makes it appear to move west to east across the sky.
Answer:
The manner in which the Earth's movement affect how the Sun is seen is;
The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky
Explanation:
The Earth's movement affect the way the Sun is seen
The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky
However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise rotation of the Earth about its axis
Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West
Answer:
The sun stays still but the rotation of the earth makes it look like it goes east to west.

A man who weights 900 N stands on a platform scale in a elevator the elevator has made 4000 kg the reading on the scale is 700 N
Answer:
a = -2.17 m / s²
Explanation:
In this problem you must ask for the acceleration of the elevator.
Let's use Newton's second law
F-W = ma
a =[tex]\frac{F}{m} - g[/tex] F / m-g
the weight of the body is 900 N and the force is the reading of the scale, let's find the mass
w = mg
m = w / g
m = 900 / 9.8
m = 91.84 kg
let's calculate
a = 700 / 91.84 - 9.8
a = -2.17 m / s²
The negative sign indicates that the elevator is going down

back ground radiation is a natural radiation so basically everything emits background radiation. so if it were harmful, the world wouldn't be here,
so it is false
it knocks electrons out of atoms, this is because ionising radiation is a radiation that had enough energy to remove electrons form the atoms and molecules.
true because exposure to radon can damage biological molecules such as proteins, which leads to abnormal patterns of cell division, which leads to cancer.
