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.

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.

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
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.

Which statement below best describes Gregor Mendel’s conclusions about genetics based on his pea plant experiments?
A. DNA is the biomolecule of life. Its structure is a double-helix and it is the blue print for the structure and function of an organism.
B. Each parent plant transmits certain factors to its offspring. These factors combine and determine the plant’s traits.
C. When two organisms reproduce, the offspring will generally result in a blending of the parent’s traits.
D. Mendel’s experiments ended up being inconclusive. Although he saw some patterns of inheritance, he was unable to determine the “how” behind it.
Answer:
B is the best answer.
Explanation:
A is off-topic considering the pea plant experiments, C is close, but too general and can be proven wrong, and D is just flat out wrong. The process of elimination leaves B to be the best answer.
A graph labeled velocity versus time with horizontal axis time (seconds) and vertical axis velocity (meters per second). A blue line runs straight across at 2 units on the vertical axis for all horizontal axis values.
Based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph?
initial = 0 m/s; final = 2.5 m/s
initial = 2.5 m/s; final = 2.5 m/s

Una caja pesa 800N descansa sobre el piso de un elevador, en determinado instante el elevador tiene una velocidad hacia abajo de 5.0 m/s y una aceleracion hacia arriba de 2.5 m/s2 ¿en ese instante cual es la fuerza aue ejerce el piso del elevador hacia abajo?
Answer:
La fuerza ejercida sobre el piso del elevador hacia abajo es aproximadamente 1,004.075 N
Explanation:
Fuerza = Masa × Aceleración
El peso de la caja = 800 N
La velocidad hacia abajo = 5.0 m / s
Tomando la aceleración debida a la gravedad, g = 9,8 m / s²
La masa del cuerpo, m = 800 N / g = 800 N / (9,8 m / s²) ≈ 81,63 kg
La fuerza ejercida sobre el piso del ascensor durante la aceleración hacia arriba, 'N', se da como sigue;
N = m · g + m · a
a = 2,5 m / s²
∴ N = 81,63 kg × 9,8 m / s² + 81,63 × 2,5 m / s² = 800 N + 81,63 × 2,5 m / s² ≈ 1,004,075 N
La fuerza ejercida sobre el piso del ascensor hacia abajo ≈ 1,004.075 N

A scientist is studying a newly created substance. She performs a test in which she keeps adding heat to the substance until it catches on fire. What type of property is she measuring?
Answer:
Chemical property (flammability).
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In this scenario, a scientist is studying a newly created substance. She performs a test in which she keeps adding heat to the substance until it catches on fire. Thus, the type of property she is measuring is a chemical property (flammability).
Flammability can be defined as a chemical property which measures the ability of a substance (matter) to ignite or burn due to the presence of oxygen and heat.

Submit
Answer:
Option A nuclear
Explanation:
The rate of electricity production in nuclear power plant is much higher as compared to the rate of electricity generation in gas, wind and solar power plants.
Thus, in case where large amount of electricity is to be produced in a short period then one must rely on nuclear power plants.
Therefore, option A is correct
Answer: Option A- Nuclear power station
Explanation: During a sudden increase in demand, Nuclear power stations can be used easily to supply the needed energy as they have an extremely short start up time. This means that the energy can be supplied in a short period of time.

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.
