The electric field intensity between two large,
charged parallel metal plates is 6000 N/C. The
plates are 0.05 m apart. What is the electric poten-
tial difference between them?
Answer:
300 is the answer
Explanation:
Hope that this answer will help you
The electric potential difference between the two large, charged parallel metal plates is 300 V.
What is the potential difference?The electric potential difference (V) between two points is defined as the work done per unit charge in moving a positive test charge from one point to another.
Mathematically,
V = W/Q
where W is the work done in moving the charge Q between two points.
Here in the Question,
In the case of two large, charged parallel metal plates, The electric field intensity (E) is given as 6000 N/C and the distance between the plates (d) is 0.05 m. The electric field intensity between the plates is uniform, which means that the force on a test charge is constant at any point between the plates.
The work done (W) in moving a positive test charge from one plate to the other against the electric field is given by
W = F × d
where F is the force acting on the test charge and d is the distance moved.
Using the formula for electric field intensity
E = F/Q
we can express force:
F = QE
Substituting this in the formula for work done, we get
W = Q × E × d.
Now, the electric potential difference (V) between the plates is given by
V = W/Q = E × d = 6000 N/C × 0.05 m = 300 V.
V = 300 V
Therefore, the electric potential difference between the two large, charged parallel metal plates is 300 V. This means that if a positive test charge is moved from one plate to the other, the work done in moving it against the electric field is 300 J per coulomb of charge.

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.

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.

1.constellation2.Probably a dwarf planeti 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.

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.

Speed =distance travelled/time taken
A body completes one round of a circular path of radius 14m in 10 seconds. Calculate its average speed and average velocity at the end of one round.
Answer:
Average speed = 8.8 m/s
Average velocity = 8.8 m/s
Explanation:
From the question,
Avearge speed = 2πr/t................ Equation 1
Where r = 14 m, t = 10 s
Constant π = 22/7
Substitute this value into equation 1
Average speed = 2(22/7)(14)/10
Avearge speed = 8.8 m/s.
For a body moving in circular motion, The average speed and average velocity are equal.
Hence,
Average speed = 8.8 m/s
Average velocity = 8.8 m/s

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]
