Frequency is reduced with the sound waves being less heard when the speaker moves away from an observer.

This is defined as the number of occurrences of a repeating event per unit of time.

As the speaker is moved away from the observer, the wavelength increases and the frequency decreases thereby resulting in less sound being heard.

Because when we polish the shoes, they gain charges or the shoes become charged, the small non-charged particles are attracted to them.

If the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

This states that

Now, given that a negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are attracted to each other the charge on the paper, this implies that both the negatively charged plastic comb and the paper have opposite charges.

Since the charge on the plastic comb is negative, this means that the charge on the paper must be positive

So, if the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

Hi there!

Begin by using Gauss' Law to find the electric field.

[tex]\oint {E \cdot} \, dA = \frac{Q_{encl}}{\epsilon_0}[/tex]

E = Electric field (N/C)
dA = differential area element

Q = enclosed charge (C)

ε₀ = Permittivity of free space (8.85 * 10⁻¹² C²/Nm²)

We can construct a large cylinder around the wire in order to determine the electric flux. The electric field lines will pass through the LATERAL surface area of the cylinder, so:
[tex]A = 2\pi rL[/tex]

Where 'L' is the length of the cylinder and 'r' is the distance from the capacitor.

The enclosed charge is equivalent to the charge per meter length (λ) multiplied by the length, so:
[tex]\oint {E \cdot} \, dA = \frac{\lambda L}{\epsilon_0}[/tex]

We can rewrite the dot product as EA (where cosθ = 1 since the normal vector points in the direction of the field).

A = the lateral surface area of a cylinder, so:

[tex]E * 2\pi rL = \frac{\lambda L}{\epsilon_0}[/tex]

Rearrange to solve for 'E'.

[tex]E = \frac{\lambda L }{2\pi r L \epsilon _0}\\\\E = \frac{\lambda }{2\pi r \epsilon_0}[/tex]

a)
Plug in the distance into 'r'.

[tex]E = \frac{\lambda }{2\pi r \epsilon_0} \\\\E = \frac{0.0000072}{2\pi * 5.5 * (8.85 * 10^{-12})} = \boxed{23542.18 \frac{N}{C}}[/tex]

b)
Repeat:
[tex]E = \frac{\lambda }{2\pi r \epsilon_0}\\\\E = \frac{0.0000072}{2\pi * 2.5 * (8.85 * 10^{-12})} = \boxed{51792.8 \frac{N}{C}}[/tex]

We can see that the distance from the wire is INVERSELY related to the electric field strength by a power of r⁻¹. The field strength DECREASES as the distance INCREASES.

We know that:

[tex]0.5m(vB^{2} -vA^{2} )=q*[VB-VA]\\== > vB^{2} =vA^{2} +(\frac{2q}{m})*[VB-VA]\\ =(4.30*10^{4} )^{2} +(\frac{2*1.6*10^{-19} }{2*1.67*10^{-27} }) [-10-30]\\[/tex]

[tex]=18.49*10^{8} -76.64*10^{8}[/tex]

[tex]=-58.15*10^{8} \\== > vB=-7.62*10^{4} m/s[/tex]

The proton's speed at point B is  -7.62 x ×10⁴ m/s.

The proton is a subatomic particle lies inside the nucleus of an atom of element. The number of proton gives an idea of the atomic number of the element.

The proton's speed as it passes point A is 4.00×10⁴ m/s . It follows the trajectory shown.

1/2m (vb² - va²) = q (Vb - Va)

vb² =  va² +2q/m (Vb - Va)

where v is the velocity and V is the potential at point A and B, q ia the charge on proton and m is the mass of proton.

Substitute the given values, we get

vb² = (4.00×10⁴ ) + (2x1.6 x 10⁻¹⁹/1.67 x 10⁻²⁷) (-10 - 30)

vb = -7.62 x ×10⁴ m/s

Thus, proton's speed at point B is  -7.62 x ×10⁴ m/s.

Answer:

About 46 billion light years Because space expands so what we didn’t see before is what we could see now. An example could be how everyone thought Pluto was a regular sized planet but once you get a look at the bigger picture and compare it to other thing in space we now know Pluto is a dwarf planet.

Yes it is possible. Spectrum of emitted light depends upon the chemical composition of the source. and the way of its excitation. a clear example to us is that of sun.

Answer:

Explanation:

As the poster has noted above in comment, the acceleration for each person will be the same. This is because when they tugon the rope, there will be tension force on the rope pulling the two persons towards each other. The tension force will be the same for them. As they also have equal mass, by Newton's Second Law of Motion, Force = mass * acceleration, their acceleration will be the same.

Answer:

Suppose Archimedes weighed the crown (we'll say 2700 grams)

Then he put the crown on a string and weighed the crown in water and found its weight to be 2560 g.

That means that an equivalent volume of water weighed

2700 - 2560 = 140 grams

Then the density of the crown is 2700 / 140 = 19.3

So this is the density of pure gold and the crown could be considered to be made of pure gold with no other metals in its composition.

Archimedes weighed the crown, then suspended it on a rope and measured the volume of water it displaced in order to determine its weight, then he calculated the density of the crown and compared it with the density of the pure gold.

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

As given in the problem statement Greek scientist called Archimedes was asked to check the purity of the gold in a crown. He did this by comparing the density of the crown with the density of pure gold.

Archimedes weighed the crown, then suspended it on a rope and measured the volume of water it displaced in order to determine its weight.

Thus, he could have measured the density of an irregularly shaped object as a crown.
