Answer:
R₃ = 4.77 x 10⁻¹⁰ m = 0.477 nm
Explanation:
In 1913, Neil Bohr proposed an atomic model theory, based upon Quantum theory of radiation. This theory described the atomic structure, removing the defects of Rutherford's Model.
In this theory Bohr also derived the formula for the radius of nth orbit of hydrogen atom. The formula is as follows:
Rn = n²(0.53 x 10⁻¹⁰) m
Where,
Rn = Radius of nth orbit of hydrogen atom
n = no. of orbit
Therefore, for 3rd orbit
n = 3
R₃ = (3)²(0.53 x 10⁻¹⁰) m
<u>R₃ = 4.77 x 10⁻¹⁰ m = 0.477 nm</u>
Answer:
2.56 x 10^-9 N
Explanation:
charge on each proton, q = 1.6 x 10^-19 C
distance between the two protons, d = 3 x 10^-10 m
The formula for the force between the two charge is given by
F = 2.56 x 10^-9 N
Thus, the electrostatic force between the two charge is given by 2.56 x 10^-9 N.
In this question a lot of information's are provided. Among the information's provided one information and that is the time of 4 seconds is not required for calculating the answer. Only the other information's are required.
Mass of the block that is sliding = 5.00 kg
Distance for which the block slides = 10 meters/second
Then we already know that
Momentum = Mass * Distance travelled
= (5 * 10) Kg m/s
= 50 kg m/s
So the magnitude of the blocks momentum is 50 kg m/s. The correct option among all the given options is option "b".
Answer:
transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
