Answer:
PART A: 412.98 nm
PART B: 524.92 nm
Explanation:
The equation below can be used for a diffraction grating of nth order image:
n*λ = d*sinθ
Therefore, for first order images, n = 1 and:
λ = d*sinθ.
The angle θ can be calculated as follow:
tan θ = 9.95 cm/15.0 cm = 0.663 and
θ = (0.663) = 33.56°
Thus: d =λ/sin θ = 461/sin 33.56° = 833.97 nm
PART A:
For a position of 8.55 cm:
tan θ = 8.55 cm/15.0 cm = 0.57 and
θ = (0.57) = 29.68°
Therefore:
λ =d*sin θ = 833.97*sin 29.68° = 412.98 nm
PART B:
For a position of 12.15 cm:
tan θ = 12.15 cm/15.0 cm = 0.81 and
θ = (0.81) = 39.01°
Therefore:
λ =d*sin θ = 833.97*sin 39.01° = 524.92 nm
The final temperature of the mixture will be <u>30⁰C</u>
Since it is given that 50 gms of water at 20 ⁰ C and 50 gms of water at 40⁰ C are mixed. Since the masses of the liquid at different temperatures are the same, the answer is very easy and simple: average of 20⁰C and 40⁰C. that is 30⁰C.
<em>the final temperature of the mixture = </em>
<em> = [ m1 * T1 + m2 * T2 ] / (m1 + m2)</em>
<em> = [ 50 gms * 20⁰ C + 50 gms * 40⁰C ] / (50+50)</em>
<em> </em><em> = 3,000 / 100 = </em><u><em>30⁰C</em></u>
In chemistry, we define the temperature of a substance as the average kinetic power of all of the atoms or molecules of that substance. No longer do all of the debris of a substance have identical kinetic strength. At any given time, the kinetic energy of the debris may be represented by means of a distribution.
Temperature performs a vital function in-hospital treatment (both humans and animals), food, beverages, and agriculture. Our average fitness is regularly reliant upon the temperature in lots of methods as nicely.
The SI unit of temperature as consistent with the global system of devices is Kelvin.

Explanation:
Answer:
C) 5970 y
Explanation:
Given;
initial amount of wood, N₀ = 15.3 cpm/g
remaining amount of wood (charcoal), N = 7.4 cpm/g
half life of carbon 14, t 1/2 = 5700 years
The age of the ashes can be calculated using the following formula;
Therefore, the ashes are 5970 years
