Answer:
15.64 KN
Explanation:
mass of the elevator cab with a single occupant= 2300 kg
acceleration relative to the cab = 6.80 m/s^2
acceleration of the coin relative to the cab in the opposite direction of motion of cab so we can consider it as a= -6.80 m/s^2
The acceleration of elevator cab relative to the ground
now we can say that
=-6.80+ a_{eg}= -9.8
[tex]a_{eg}=-9.8+6.80=-3.8
The forces that act on elevator cab are tension and gravitational, applying newtons second law
T- mg= ma_{eg}
Then the tension in the cable is
T= 2300(-3.8)+2300×9.8= 15640 N= 15.64 KN
therefore tension in the string will be 15.64 KN
Answer:
So the two wavelength range will over lap
Explanation:
The Rydberg equation is given by
m is the mass of electron
k = 1/4π∈₀
∈₀ = is the permitivity of free space
e is the charge of electron
h is the plank constant
c is the speed of light in vaccum
z is the atomic number = 1
where R is the Rydberg constant = 1.097373 × 10⁷m⁻¹
For Paschen series of H spectrum
in Paschen series of H spectrum
The maximum wavelength occur for
The minimum wavelength occur for = ∞
The brackett series of H spectrum
The maximum wavelength occur for
The minimum wavelength occur for = ∞
So the two wavelength range will over lap
