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.

galaxies are actually racing away from Earth at high speeds. Which
statement is best supported by this discovery?
A. Science is a body of knowledge that is a subject to change based on data.
B. A hypothesis can become a law.
C. Science is a body of knowledge based on the work of well-known scientists.
D. A hypothesis is the correct answer to a problem.
The position of galaxies in the universe was once hypothesized to be
constant, but evidence gathered by Edwin Hubble indicated that many
galaxies are actually racing away from Earth at high speeds. the
statement that is best supported by this discovery is Science is a body of knowledge that is subject to change based on data, therefore the correct answer is option A
What is the scientific claim?Scientific claims are statements made in science based on an experiment.
These Scientific claims are backed by the experimental data and their true results obtained from scientific investigation and experimentation.
The position of galaxies in the universe was once thought to be fixed, but Edwin Hubble's observations revealed that many galaxies are actually moving away from Earth quickly. The conclusion that this discovery best supports is that science is a body of knowledge that is subject to change based on data, so option A is the appropriate answer.

What does the number, or density, of field lines on a source charge indicate?
OA
direction of charge on the source charge
B.
amount of charge on the test charge
Oc.
amount of charge on the source charge
OD
direction of charge on the test charge
Reset
Next
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.
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.

Explanation:
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.

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.

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!
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 does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from the air through a diamond.
answer both questions
(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.
