The ____ of an objects is give relative ro an origin
leva [86]

The position of an object is given relative to an origin.

'Origin' here simply means a standard point of reference. For example, when we plan to go to a supermarket in our locality, we think of how many streets or blocks away that place is from our house. Here our house serves as the origin about which we locate the position of several stores.

a)Show that whennbecomes very large, the energy levels of the hydrogen atom are getting closer to energy.b)Are the rays of these
natali 33 [55]

Answer:

Answered

Explanation:

Energy of electron in  hydrogen atom is given by

E_n= \frac{13.6}{n^2}

now as becomes large

ΔE= E_n+1 - E_n= 18.6 eV(1/n^2- 1/(n+1)^2)

now, as n increases ΔE_n decreases

in the limit n→∞ ,  ΔE_n→0. Thus with increase in n, energy level come close to each other.

b) Since, the wavelength of the rays depends upon the energy level hence they too come closer.

c)Near the ionization threshold the energy level of the atoms come closer and the total energy of the electron becomes almost so that it can be easily removed from the orbit.

Provided the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from a
riadik2000 [5.3K]

Answer:

Check the explanation

Explanation:

The beat frequency is

df = f2 - f1

the wavelength is

lamda1 = (v/f1)

and lamda2 = (v/f2)

where v = 340 m/s,f1 = 25.0 kHz and f2 = 20.0 kHz
