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.

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.

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.

Lightning flashes and you hear a thunder clap for seconds later. the velocity of sound is 340 m/s. how far away did lightning strike ?
Answer:
For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.
Explanation:
hope it hep and if it doesnt sorry
The distance struck by the lighting flashes is 680 m.
The given parameters;
time taken to hear the thunder clap, t = 4 svelocity of sound, v = 340 m/sThe distance struck by the lighting is calculated by applying the principle of echo as follows;
[tex]v = \frac{2d}{t} \\\\2d = vt\\\\d = \frac{vt}{2} \\\\d = \frac{340 \times 4}{2} \\\\d = 680 \ m[/tex]
Thus, the distance struck by the lighting flashes is 680 m.

What happens when light runs into object
Explanation:
It depends on the object, actually. If the object is transparent or somewhat clear, the the light will end up refracting, or bending, through those clear objects. It can also bounce off objects, too. But, with some objects, the light can be blocked, or absorbed.
Answer:
See down below
Explanation:
When light hits glass or any other transparent material, it pass though. Some light is reflected off the object whereas the rest passes through and is refracted. As light passes through air and into another clear material it changes speed, and light is both reflected and refracted by the glass.When the light runs into a sold object, it prevents from going through it.

Answer:
C. amount of charge on the source charge.
Explanation:
Electric field lines can be defined as a graphical representation of the vector field or electric field.
Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.
The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.

a= ?
v=
r=
Answer:
[tex]a=\frac{v^2}{r}[/tex]
[tex]v=\sqrt{a*r}[/tex]
[tex]r=\frac{v^2}{a}[/tex]
Explanation:
This is the formula for centripetal acceleration in terms of the tangential velocity (v) and the radius of the circular motion (r). The expression for the acceleration is already given, so simply type it as shown:
[tex]a=\frac{v^2}{r}[/tex]
For the velocity (v) multiply by "r" both sides and then use the square root to solve for v:
[tex]a*r=v^2\\v=\sqrt{a*r}[/tex]
For the radius multiply both sides by r and then divide both sides by the acceleration (a) in order to isolate r completely:
[tex]a*r=v^2\\r=\frac{v^2}{a}[/tex]
