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}

A soccerball is kicked straight out from a hill at 15 m/s and lands 42m away. how tall is the hill
ozzi

Answer:

The height of the hill is, h = 38.42 m

Explanation:

Given,

The horizontal velocity of the soccer ball, Vx = 15 m/s

The range of the soccer ball, s = 42 m

The projectile projected from a height is given by the formula

                             S = Vx [Vy + √(Vy² + 2gh)] / g

Therefore,

                            h = S²g/2Vx²                     (Since Vy = 0)

Substituting the values

                             h = 42² x 9.8/ (2 x 15²)

                                = 38.42 m

Hence, the height of the hill is, h = 38.42 m

A cup of coffee is sitting on a table in a train that is moving with a constant velocity. The coefficient of static friction bet
Vikki [24]

Answer:

a = 2.94 m/s²

Explanation:

In order for the cup not to slip, the unbalanced force on cup must be equal to the frictional force:

Unbalanced Force = Frictional Force

ma = μR = μW

ma = μmg

a = μg

where,

a = maximum acceleration for the cup not to slip = ?

μ = coefficient of static friction = 0.3

g = acceleration due to gravity = 9.8 m/s²

Therefore,

a = (0.3)(9.8 m/s²)

<u>a = 2.94 m/s²</u>

tankabanditka [31]

Explanation:

Radio Telescope:

1. FAST (Five Hundred Meter Aperture Spherical Telescope), China is the largest single dish radio telescope in the world with a dish of diameter 500 meters. Although its construction is over but its not yet functional.

2. Arecibo Observatory, Puerto Rico is the largest single dish <em>operational</em> radio telescope having a single dish of diameter 305 meters..

X - ray Telescope: Chandra X ray observatory also known as Advanced X-ray Astrophysics Facility (AXAF) is the largest x-ray telescope with aperture of 1.2 meters. It can detect X-ray sources which are 100 times fainter in comparison to any previous telescope.

Gamma ray telescope: Fermi Gamma ray telescope is the largest gamma ray telescope.
