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}

Answer:

2 m/s²

Explanation:

the equations of motion are

S= ut +½at²

v² = u²+ 2as

v = u + at

s = (u+v)/2 × t

From the parameters given

u = 0m/s this is because it starts from rest

Distance (s)  = 9m

Time (t)  = 3s

Based on this the first equation would be used

s = ut + ½at²

Input values

9 = 0×3 + ½ × a x 3²

9 = 0 + 9a/2

9 = 4.5a

Divide both sides by 4.5

a = 9 / 4.5 m/s²

a = 2 m/s²

An element’s atomic number is 35. how many portions would an atom this element have
kotykmax [81]

35 protons are present in an element whose atomic number is 35.

<u>Explanation: </u>

In an atom of an element, the number of protons = atomic number

Number of protons = number of electrons

Mass Number = number of protons + number of neutrons

Hence, an atom with atomic number 35 will have 35 protons.

A car is initially moving at 35 km/h along a straight highway. To pass another car, it speeds up to 135 km/h in 10.5 seconds at
Aleks04 [339]
Acceleration = (velocity final-velocity initial)/ time
where
velocity final = 135 km/hr x 1 hr /3600 s x 1000m/1km
                     = 37.5 m/s
velocity initial = 35 km/hr x  1hr /3600 s x 1000 m/1 km
                      =  9.72 m/s
a) acceleration = 2.646 m/s^2
b) acceleration in g units  = (2.646m/s^2)/(9.8m/s^2)
                                              = 0.27 units
