Answer:
at n= 3 λ = 656 nm
at n= 2 λ = 121.58 nm
Explanation:
Given details
transition of hydrogen atom from n = 2 to n = 3 state
Difference in energy between n = 3 state and n = 2 state :
so, energy of photon is given as
So solve for wavelength
so, λ
=
= 656 nm
for second transition,
energy transmitted is given asΔE
and it is calculated as
E = 1.635*10-18 J solving for wavelength in ENERGY equation we get
so, m
= 121.58 nm
Answer:
Difference between tangential and angular acceleration are mentioned in points.
Explanation:
We have to find the difference between tangential and angular acceleration:
Tangential acceleration :
- Its function is to change the magnitude of velocity.
- Defined as rate of change of linear speed.
- Formula
Angular acceleration :
- Its the rate of change of angular acceleration.
- Its value is same for different location of the same body.
- It is also the ratio of tangential acceleration and Radius.
- Formula and
Answer:
Explanation:
Edit to add part a
a) Heating a gas causes the atoms to increase their kinetic energy. With only atmospheric pressure to contain it, the gas will decrease in density by pushing colder gas out of the way. The lid is then sealed to the jar and allowed to cool. The cooling gas, now constrained by the volume of the jar will be forced to lower its pressure to maintain equilibrium. The lower pressure inside the jar will allow the atmospheric pressure outside the jar to "click" the lid indicating a proper seal.
b Before opening there is a much lower pressure inside the jar than outside. The outside pressure keeps the lid constantly in the "clicked" position.
c After the jar is opened, the pressure on either side of the lid is equal and an unbalanced force applied to one side of the lid or the other can cause the lid to "click" or "unclick" depending on the initial position.
Answer:
5,126 N*m
Explanation:
Since the magnitudes are vectors, the Pythagoras theorem can be used to find the resulting vector ((1,8^2 + 4,8^2)^1/2). The direction of this vector will be contained in the X-Y plane, specifically in the fourth quadrant in Cartesian coordinates.
