How do electromagnetic fields work?
Answer:
Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
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.

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.

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:

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.

If
you lift a 5 Kg bowling ball with a force of 49 N to a height of 40 m, what is the amount of work done on the
bowling ball to lift it?
Answer:
Workdone = 1960 Joules.
Explanation:
Given the following data;
Mass = 5kg
Force = 49N
Height (distance) = 40m
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 49*40
Workdone = 1960 Joules.
Therefore, the amount of work done on the bowling ball to lift it is 1960 Joules.

Explanation:
Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type
Ca Co3 + H2SO4 → CO2 + H2O + CaSo4
Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh

Explanation:
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.

When a substance freezes, its atoms become locked in place so they do not move from one position to another. Therefore, any substance that is frozen is a
plasma.
gas.
liquid.
solid.
When a substance freezes, its atoms become locked in place so they do not move from one position to another. Therefore, any substance that is frozen is a solid. Hence, option (D) is correct.
What is solid?One of the four basic states of matter is solid (the others being liquid, gas, and plasma). The least solid molecules are those that are tightly packed together and make up solids.
A solid is distinguished by its structural rigidity and resistance to external forces. A solid substance, unlike a liquid, does not flow to conform to the shape of its container or, like a gas, expand to cover the entire space. A solid's atoms are connected to one another either in a regular geometric lattice (such as that found in metals and common ice), or in an asymmetrical manner (an amorphous solid such as common window glass).
Therefore, any substance that is frozen is a solid.

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
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
