Bohr explained that the electron revolve around a orbit of fixed energy level that Rutherford fails to explain !!!

Answer:

As we know that as per Rutherford's model we have will have an model in which he said that there is a small center at which whole positive charge is concentrated in an atom and all electrons will revolve around that positive charge.

So here in Rutherford's model he describe about the nucleus of the atom.

Now in Bohr's model he said that the orbit in which all electrons revolve around the nucleus is known as stationary orbit and there is no energy loss in that orbit when electron revolves in it.

So here we can say that in Bohr's model he included the part of stationary orbit which is not included in Rutherford's model.

As we can say that in Bohr's model the energy of electron is constant when it revolves in its stationary orbit and when electron changes its orbit then energy will be released in form of photons.

For stationary orbit the angular momentum of the electron must be integral multiple of \frac{h}{2\pi}

so it is

mvr = \frac{Nh}{2\pi}

Although 0 dB is often referred to as the lower threshold of human hearing, it is important to realize that the human ear is not
IRISSAK [1]

Answer:

20 Hz

15.8 times

Explanation:

A

Although the range of frequency for any human's ear is usually said to be between 20 Hz and 20 kHz. And since the question asked for the least intense frequency, that has to be 20 Hz. Essentially the frequency most people perceive the least intense sound is 20 Hz.

B

A 100-Hz sound must be 10^1.2 times or 15.8 times more intense compared to a 1000-Hz sound to be perceived as equal to 60 phons of loudness

9.The force of gravity between two asteroids is 10,000 newtons (N).
MakcuM [25]

Answer:

F1 = G m1 m2 / R^2        force of attraction

F2 = G m1 m2 / (R/2)^2

F2 / F1 = 4       the force of gravity will be quadrupled

Two power lines run parallel for a distance of 220 m and are separated by a distance of 40.0 cm. If the current in each of the t
daser333 [38]

Answer:

The magnitude of force is 1.86 N and the direction of force is towards the other wire.

Explanation:

Given:

Current flowing through each power line, I = 130 A

Distance between the two power lines, d = 40 cm = 0.4 m

Length of power lines, L = 220 m

The force exerted by the power lines on each other is given by the relation:

F = \frac{\mu_{0}LII }{2\pi d}

Substitute the suitable values in the above equation.

F = \frac{4\pi\times10^{-7}\times220\times130\times130 }{2\pi\times0.4}

F = 1.86 N

Since the direction of current flowing through the power lines are opposite to each other, so the force is attractive in nature. Hence, the direction of force experienced by the power lines on each other is towards the each other.
