what is aerobic activities
Answer:
Aerobic exercise is any type of cardiovascular conditioning. It can include activities like brisk walking, swimming, running, or cycling. You probably know it as “cardio.”
By definition, aerobic exercise means “with oxygen.” Your breathing and heart rate will increase during aerobic activities. Aerobic exercise helps keep your heart, lungs, and circulatory system healthy.
Aerobic exercise differs from anaerobic exercise. Anaerobic exercises, such as weightlifting or sprinting, involve quick bursts of energy. They’re performed at maximum effort for a short time. This is unlike aerobic exercises. You perform aerobic exercises for a sustained period of time.
Explanation:
Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism
how does electic motor and generator work?
Answer:
the answer is below
Explanation:
When an electrical current is applied to the motor, the magnets or windings create a magnetic field that both attracts and repels the rotor, causing it to spin. ... Rather than using electricity to create motion, electric generators in Lethbridge convert mechanical energy into electrical energy.
An electric motor is a machine that transforms electrical energy into mechanical energy.
It is made up of a magnet (typically a permanent magnet) and an electromagnet that are both situated close to each other.
The magnet generates a magnetic field, whereas an electromagnet is created by transmitting an electric current via a wire coil.
A magnetic field is created around the coil when an electric current travels through it. The Lorentz force is exerted on the coil as a result of the interaction between the magnetic fields of the coil and the magnet. This force causes rotational motion in the coil, forcing it to revolve.
An electric generator operates on the electromagnetic induction principle.
It is a device that transforms mechanical energy into electrical energy. A generator's essential components are a wire coil and a magnet (often an electromagnet).
The lines of magnetic force travelling through the coil vary when the coil is rotated inside the magnetic field.
Thus, as defined by Faraday's law of electromagnetic induction, this shift in magnetic flux creates an electromotive force (EMF) or voltage in the coil.

When the distance between two objects doubles, what happens to the gravitational attraction between these two objects?
Answer:
As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straightforwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.
The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.
At that point by Newton's All inclusive Law of Attractive energy;
F=GMm/R^2
Mm= result of the majority
R=Distance Between the two masses by focus.
On the off chance that R is multiplied, new force=GMm/(2R)^2
=GMm/4R^2
Unique Power/New Force=4/1
F/4=New Power

State the Law of Electric Charges in your own words.
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

The greatest gravitational force would occur between the moon and Earth. The correct option is D.
What is Gravitation?The force of gravity, also known as gravitation, affects every material object in the universe. The force of gravity tends to draw any two objects or particles with nonzero mass toward one another. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
The two forces, which are equal in strength and move in the opposite direction, pair up to interact with various objects. As a result, the pull of Earth on the Moon is equal to and opposes the pull of the Moon on Earth.
Amongst the given options the greatest force is between the moon and the earth.
Hence, the greatest gravitational force would occur between the moon and Earth. The correct option is D.

How would you explain to a 5 year old how to make their hands move to show each type of plate boundary with their hands. Convergent (2 ways to move your hands, to make mountains /to show subduction). Divergent (1 way to move your hands). Transform (1 way to move your hands)? Gosh, my teacher needs 3 paragraphs.
Answer:
Theirs plenty of ways to move you´re hands. You can make you´re hands wave like the ocean and as well make them move together to create a sound which is called clapping.
You can move your hands by poking your fingers together or you can hide your face by putting your hands on your face. You can also play peek a boo while you hide your face by taking you´re hands off you´re face.
Their is many ways to move your hands, They have big words for it too. The big words would be Convergent, Divergent and Transform.

A dog running with an initial speed of 7.5 m/s comes to a stop in 5 seconds. What is the
dog's displacement?
Answer:
4.6
Explanation:
If a dog running with an initial speed of 7.5 m/s comes to a stop in 5 seconds, then the displacement of the dog would be 37.5 m / s .
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.
As given in the problem If a dog running with an initial speed of 7.5 m/s comes to a stop in 5 seconds, then we have to find the displacement of the dog.
The displacement of the dog = 7.5 × 5
= 37.5 m /s
Thus , If a dog running with an initial speed of 7.5 m/s comes to a stop in 5 seconds, then the displacement of the dog would be 37.5 m / s .

What is the kinetic energy of a 0.50 KG ball that is traveling at a speed of 40m/s
Answer:
0.4kjKE = 1/2 mv2
KE = 1/2 mv2 KE = 1/2 (0.50kg) (40m / s)
KE = 1/2 mv2 KE = 1/2 (0.50kg) (40m / s) 2 KE = 1/2 (0.50) (402)
KE = 1/2 mv2 KE = 1/2 (0.50kg) (40m / s) 2 KE = 1/2 (0.50) (402) KE = 0.5 x 0.50 x 402
KE = 1/2 mv2 KE = 1/2 (0.50kg) (40m / s) 2 KE = 1/2 (0.50) (402) KE = 0.5 x 0.50 x 402 KE = 400 J
KE = 1/2 mv2 KE = 1/2 (0.50kg) (40m / s) 2 KE = 1/2 (0.50) (402) KE = 0.5 x 0.50 x 402 KE = 400 JKE = 0.4 KJ
