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.

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.

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.

Preview this picture of a roller coaster. Does it make you feel safe? How does the picture reinforce the idea of roller coasters being safe as stated in the article?
Answer: The coaster tracks serve to channel this force — they control the way the coaster cars fall. ... If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt-up, gravity applies a downward force on the back of the coaster, so it decelerates.
Explanation: They may be safe though!

A 15kg boulder is moved from the Earth to the Moon. Explain what happens to the mass and weight of the boulder.
Answer:
The mass of the boulder remains constant, while its weight decreases with respect to the value of gravitational force on the moon.
Explanation:
The mass of the boulder = 15 kg
On the earth, its mass remains 15 kg. But its weight is;
weight = m x g
= 15 x 9.8
= 147 N
The boulder's weight on the earth is 147 N.
When transferred to the moon, the mass remains constant i.e 15 kg. But its weight decreases due to a change in the value of acceleration due to gravity on the moon. Thus, the boulder becomes lighter in weight.

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.
