How much energy is transferred when the potential difference is 12V and the charge is 7.5C?
The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.
What is energy?
In physics, energy is the capacity to carry out work. It might be potential, kinetic, thermal, electrical, chemical, radioactive, etc., among other types. Heat and work are other examples of energy being transferred from one body to another. Once it has been transmitted, energy is always allotted according to its nature. As a result, heat transmission could result in thermal energy while effort could provide mechanical energy.
Given the information in the question:
The potential difference, V = 12 Volts,
The charge, q = 7.5 C,
Calculate the energy, E by the formula given below,
E = [tex]VQ[/tex]
Substitute the values of charge and potential difference,
E = [tex]12*7.5[/tex]
E = [tex]90 Joules[/tex]
Therefore, the energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

The SI unit for energy is Newton true or false
Explanation:
false....it is joules
..........
The answer is false
The SI unit for energy is joules and not Newton. Energy can be described as the capability of an individual to perform work. Every day all living things carry out one form of work or the other. These might include walking, running, cooking, singing, driving etc. All these activities require energy, some require a whole lot of energy.
This is why the importance of energy for our day to day activities cannot be over emphasized.
Hence the SI UNIT for energy is joules.

How does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from the air through a diamond.
answer both questions
(1.) The Phenomena of Refraction Occurs when a Ray (Here Light) enters a Relatively Denser or Rarer Medium and Due to the Change in Density, the Speed of the Incident Ray Decreases or Increases Respectively.
(2.) If a light ray projected through a diamond, the light would refract drastically.
i have a physAn e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.
Which electrical device operates because of this effect?ics exam someone please help 9th grade &
Answer:
Generator.
Explanation:
In a generator, an e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.
The mode of operation of a generator is that a metal core with copper tightly wound to it (conductor coil) rotates rapidly between the two (2) poles of a horseshoe magnet type. Thus when the conductor coil rotates rapidly, it cuts the magnetic field existing between the poles of the horseshoe magnet and then induces the flow of current.

PLEASEE HELPPLook at the diagram of two students pulling a bag of volleyball equipment. The friction force between the bag and the floor is 4 N. What is the net force acting on the bag? What direction is the bag moving in?
Answer:
The net force is 21 N, and the bag will go to the right.
Explanation:
You can find the net force by adding both values of the boy and the girl, and then subtracting four from it. You can also figure out which direction its moving by looking at which side is exerting the most force, which would be the right side.

Why didn’t the liquid methane change phase before 2007?
The basic reason is that before 2007 their were not enough energy in the liquid methane molecules to break the bond between them after 2007 the energy of the molecules increases which breaks the bond and the liquid methane changes phase.
Why didn’t the liquid methane change phase before 2007?It had been summer since 2002, but the lake didn’t evaporate until 2007.
The molecular attraction between methane molecules is stronger the amount of energy absorbed by liquid methane was not enough to break the inter molecular forces until 2007.
After 2007, the sun had transferred enough energy so that the kinetic energy of the methane molecules increased enough to overcome the attraction between them.
The liquid methane evaporated and the molecules started moving away from each other.
Thus the liquid methane starts to change phase after 2007 by getting enough energy from the sun.
