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.

they can have the momentum if only they are been divided by another number to see the difference

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

KE = 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

Answer:

Explanation:

Heat always flows through from a higher thermodynamic potential to lower thermodynamic potential.

It can be defined as the branch of science that deals with the interactions of thermal energy across different system and their surroundings.Thermodynamics does not deal with the rate of energy interaction.The movement of the thermal energy depends on the thermodynamic potential of the respective objects or bodies in which the flow of the thermal energy is involved.

The thermodynamics potential is analogous to the electrical potential what is used to flow the current in the electrical circuit in the similar fashion the temperature gradient is the driving force that is used for the transfer of heat energy from a higher temperature potential to the lower to a temperature potential.
This natural flow of heat is valid only when any external work is not done on the thermodynamic system where transfer of heat taking place .

This principle of heat transfer is not applicable in the case of refrigerator and air-conditioner because in that case some external work is done on the system and is the natural driving force of heat transfer.

Hence,we can say that heat always flows through from a higher thermodynamic potential to lower thermodynamic potential unless until some external prime mover is provided for example in case of air conditioner.

The greatest gravitational force would occur between the moon and Earth. The correct option is D.

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.

Answer:

Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

Sally's mass on Moon is: C. 50 kg

Mass is a measure of the amount of matter that an object or a body is typically made up of. The standard unit of measurement for the mass of an object is kilograms (kg).

Regardless of the location of a person, an object at any given time, mass (amount of matter that they're made up of) is always the same i.e constant.

This ultimately implies that, whether you're on the Moon, space, planet Earth or any other place; your mass would always remain the same or constant.

In this scenario, Sally's mass on Earth is 50 kg. Thus, we can deduce that her mass on Moon would be 50 kg.

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

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.
