Light of wavelength 656 nm and 410 nm emitted from a hot gas of hydrogen atoms strikes a grating with 5300 lines per centimeter.
padilas [110]

Answer:

20.32^{\circ} and 44.08^{\circ}

12.56^{\circ} and 25.77^{\circ}

Explanation:

\lambda = Wavelength

\theta = Angle

m = Order

Distance between grating is given by

d=\dfrac{1}{5300}\\\Rightarrow d=0.0001886\ \text{cm}

\lambda=656\ \text{nm}

We have the relation

d\sin\theta=m\lambda\\\Rightarrow \theta=\sin^{-1}\dfrac{m\lambda}{d}

m = 1

\theta=\sin^{-1}\dfrac{1\times 656\times 10^{-9}}{0.0001886\times 10^{-2}}\\\Rightarrow \theta=20.35^{\circ}

m = 2

\theta=\sin^{-1}\dfrac{2\times 656\times 10^{-9}}{0.0001886\times 10^{-2}}\\\Rightarrow \theta=44.08^{\circ}

The first and second order angular deflection is 20.32^{\circ} and 44.08^{\circ}

\lambda=410\ \text{nm}

m = 1

\theta=\sin^{-1}\dfrac{1\times 410\times 10^{-9}}{0.0001886\times 10^{-2}}\\\Rightarrow \theta=12.56^{\circ}

m = 2

\theta=\sin^{-1}\dfrac{2\times 410\times 10^{-9}}{0.0001886\times 10^{-2}}\\\Rightarrow \theta=25.77^{\circ}

The first and second order angular deflection is 12.56^{\circ} and 25.77^{\circ}.

Consider a drug that is taken in 40 mg doses daily. suppose that the first dose is taken when t = 0 and that t is measured in ho
yulyashka [42]
There are 4 questions related to this problem:
1 If the half-life of the drug is 7.3 hours, what fraction of the drug remains in the patient after 24 hours?The amount of the drug is halved every 7.3-hour period, and 24 hours equals 24/7.3 of these halving periods. 
So the portion of the drug left over after 24 hours is (1/2) ^ (24/7.3) = 0.10224 2 Write a general expression for the amount of the drug in the patient immediately after taking the nth dose of the drug
One method is to combine the residual amounts from each amount, when the nth dose arises; this will contain adding a finite geometric series
So the total amount of the drug immediately after the nth dose, in mg, is An = 40+ 40(0.10224) + 40(0.10224)^2 + ... + 40(0.10244)^(n-1) 
An = 40[1 - (0.010224)^n]/(1 - 0.10224) 
3 Write a broad expression for the quantity of the drug in the patient directly before taking the nth dose of the drug
Pn = An – 40
= 40(0.10224) + 40(0.10224)^2 + ... + 40(0.10244)^(n-1) 
= 40(0.10224) [1 - (0.10224)^(n-1)]/(1 – 0.10224) 
= 4.0895 [1 - (0.10224)^(n-1)]
4 What is the long-term minimum amount of drug in the patient?
= lim n-->infinity of Pn 
= lim n-->infinity of 4.0895[1 - (0.10224)^(n-1)] 
= 4.0895(1 - 0) 
= 4.0895 mg.

This is a term use to describe an ecological community in which moisture and temperature are high
Yuri [45]

It is described as having a marshy surface where mosses, lichens, berries and low shrubs grow with mucky soil and permafrost underneath. This is a term use to describe an ecological community in which moisture and temperature are high. This is a northern hemisphere habitat with wet soil.

What do you mean by kinetic energy and potential energy ?
Verizon [17]

  • Kinetic Energy of an object is the measure of the work an object can do by virtue of its motions..

  • Formula - KE = 1/2 mv^2

  • Where KE is the kinetic energy, m is the body’s mass, and v is the body’s velocity.

  • Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts..

  • Formula - W = mgh

Where,

. m is the mass in kilograms

. g is the acceleration due to gravity

. h is the height in meters

Hope it helpz~ uh..
