"Two point charges exert a 6.50 N force on each other. What will the force (in N) become if the distance between them is increas

ed by a factor of 8?"
Physics

MariettaO [177]3 years ago
5 0

Answer:

0.102N

Explanation:

According to Coulomb law, the charge force between 2 points charge is directly proportional to the product of the charges and inversely proportional to the square of distance between the point charges. This means if the distance between them is increased by a factor of 8, then the charge force must be decreased by a factor of 8*8 = 64.

So the new charge force F = 6.5 / 64 = 0.102 N

Explain the difference between SI base units and SI delivered units
castortr0y [4]

SI Units are based on meters, kilograms, seconds, amperes, kelvins, candelas, and moles, together with a set of prefixes to indicate multiplication or division by a power of ten.

There are seven SI base units, which are:

m - Meter - Length.

s - Second - Time.

mol/Mole - Amount of Substance.

A - Ampere - Electric Current.

K - Kelvin - Temperature.

cd - Candela - Luminous Intensity.

kg - Kilogram - Mass.

I think that the delivered units are how they are used such as watts which are equal to one joule per second. Others are “ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV)), and foot-pounds per minute.”

So, SI base units are the basic units of things such as length or temperature. This would mean that the delivered units are the specific units per something like miles per hour.

Classify:Energyis the ability to exert force and cause change. Energy has manyforms:
Grace [21]

Answer:

Energy: Kinetic, Sound, Thermal, gravitational, electric, light and nuclear

Explanation:

This exercise asks to clarify a little some important concepts

* Energy. It is the capable one that has the bodies to carry out a job.

* Kinetic energy. It is the energy due to the movement of objects

* sound energy. It is the energy due to the vibration of the atoms or molecules of the materials, it can be solid, liquid or gaseous

* Thermal energy. It is the energy due to movement of the particles

* Gravitational Energy. It is a configuration energy due to the height of the bodies with respect to a reference point

* Electric power. It is due to the movement of electric charges

* light energy. It is the energy that light carries due to the electric and magnetic fields that form it, it occurs throughout the electromagnetic spectrum

* Nuclear energy. It is the energy stored in the nucleus by the configuration and movement of protons and neutrons.

Why would researchers not be allowed to recreate the Little Albert experiment today?
wariber [46]

Answer:

Explanation:

En la historia de la ciencia se han dado auténticas barbaridades. Pruebas con animales que hoy no perdonaría nadie, o investigaciones de conducta con personas como la de la cárcel de Stanford, que se han saldado como una especie de pasado incómodo sobre los límites de la experimentación. Sin embargo, pocos se pueden acercar por su carácter perturbador al denominado experimento de Little Albert o Pequeño Albert: El salvaje intento por probar con un bebé que las fobias pueden ser condicionadas y aprendidas. Y lo que es peor, conseguirlo.

Esta idea surgió de la mente de John Broadus Watson, reconocido padre de la rama conductista de la psicología, que desde 1913 había comenzado a probar en animales sus tesis. Estas bebían directamente del los estudios de Iván Pavlov, fisiólogo ruso que ganó el Nobel en 1904 por sus estudios sobre el sistema digestivo, pero que también sentó precedentes sobre la psicología.

Learning Goal: To understand the concepts explaining the operation of transformers.
Alex

Answer:

Part a)

ZERO

Part b)

N = 10 turns

Explanation:

Part a)

As we know that transformer is used to change the input voltage into required output voltage

Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.

So if we have input Source is DC source then output voltage will be zero as there is no flux change

Part b)

As we know by the principle of transformer

\frac{V_1}{V_2} = \frac{N_1}{N_2}

\frac{500}{25} = \frac{200}{N_2}

N_2 = 10

so total number of turns in secondary coil must be 10
