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;

The 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.

(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.

The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

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.

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.

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.

These all can impact the magnetic properties

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

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.

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.

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.

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.

m=1400kg

mass of car =1400kg

Answer:1400kg

Explanation:

Answer:

Explanation:

First of all we shall calculate mass of copper to be calculated from the formula below.

mass = volume x density

volume = total surface area x thickness of layer

= 12 x 12 x 2 x .01 cm³

= 2.88 cm³

mass = 2.88 x 9 = 25.92 g .

Let time required be t s .  .

charge flowing in time t = 1.5 t coulomb.

Given ,

1 coulomb deposits .00033 g of copper

1.5 t deposits    .00033 x 1.5 t g of copper

So ,

.00033 x 1.5 t = 25.92

t = 52364 s

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.
