Physics

Answer: Models.

Explanation: Models have usually used to simplification the harder subjects, and make it easier to work with.

An example of this is when you do the math for a car moving in the street, where you suppose that the car has an easy shape, like a box, you ignore things like air resistance and such.

Models are used in almost every field of physics, especially in the experimental field, where having a lot of variables is a problem, so the scientist develops models where some of the variables can be ignored, and in this way, the experiment and the math are easier.

An infinite plane of charge has surface charge density 7.2 μC/m^2. How far apart are the equipotential surfaces whose potential
Rina8888 [55]

Answer:

so the distance between two points are

d = 0.246 \times 10^{-3} m

Explanation:

Surface charge density of the charged plane is given as

\sigma = 7.2 \mu C/m^2

now we have electric field due to charged planed is given as

E = \frac{\sigma}{2\epsilon_0}

now we have

E = \frac{7.2 \times 10^{-6}}{2(8.85 \times 10^{-12})}

E = 4.07 \times 10^5 N/C

now for the potential difference of 100 Volts we can have the relation as

E.d = \Delta V

4.07 \times 10^5 (d) = 100

d = \frac{100}{4.07 \times 10^5}

d = 0.246 \times 10^{-3} m

Which statement correctly describes gravity?
Advocard [28]

Answer:

a force that attracts matter to the earth

Explanation:

depends on where you are the gravity can be different in space there is no gravity on Earth there is , that's why when you jump you come back down

What measurements or observations tells you that a car is accelerating
lutik1710 [3]

You need to observe the car at two different times.

-- The first time: 
You write down the car's speed, and the direction it's pointing.

-- The second time:
You write down the car's speed and the direction it's pointing, again.

You take the data back to your lab to analyze it.

-- You compare the first and second speed. If they're different,
then the car had acceleration during the time between the two
observations.

-- You compare the first and second direction.  If those are different,
even if the speeds are the same, then the car had acceleration during
the time between the two observations.

(Remember, "acceleration" doesn't mean "speeding up". 
It means any change in speed or direction of motion.)

Match the property of a sound wave to the correct definition. A. amplitude . B. frequency  . C. period . D. pitch  E. loudness 
Maru [420]

Amplitude: How dense the medium is in the compression part of the wave, and how empty the rarefied area is.

Frequency: The number of wavelengths that pass a position in 1 second.

loudness: The quality of the sound that is most closely linked to the amplitude of the sound wave.

Period: The amount of time that it takes one wavelength to pass by a position.

Pitch: The quality of the sound that is most closely linked to the frequency of the sound wave.

Damm [24]
Gravitational potential energy  = 

                        (mass)  x  (gravity)  x  (height)

                =    (5.8 kg)  x  (9.8 m/s²)  x  (2.5 m)

                =           142.1 Joules         (C)
