The order of increasing energy is red, yellow, and blue

In physics for a given wave function, the wavelength is defined as the distance between two consecutive points in the waveform. Light is considered a wave and a particle. White light can split into colors of different wavelengths.

The wavelength of visible light ranges from 300 to 700 nm comprising the color VIBGYOR. Wavelength is calculated by the formula velocity divided by the frequency.

If the frequency of the given form is high, then the energy is also high.

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).

As the frequency is inversely proportional to the wavelength, the energy is also inversely proportional. A higher wavelength will have lower energy.

The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many second
vesna_86 [32]

Answer:

It will take 140.76 seconds to swim 0.150 miles.

Explanation:

Distance covered by man by swimming for t time= d

d = 1500.0 miles

t = 14 minutes + 34.56 seconds

1 min = 60 seconds

t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds

Speed of the man while swimming = S = \frac{1500.0 m}{874.56 s}=1.715 m/s

If the man swims 0.150 miles with the same speed ,then the time taken by him be T.

0.150 miles = 0.150 × 1609.34 m = 241.401 m

(1 mile= 1609.34 meters)

S=\frac{Distance}{time}=\frac{241.401 m}{T}

1.715 m/s=\frac{241.401 m}{T}

T = 140.76 seconds

It will take 140.76 seconds to swim 0.150 miles.

According to le châtelier’s principle, the amount of solid reactant or product present does not have an impact on the equilibriu
Inessa05 [86]

The concentration of solids is constant and usually taken equal to unity ,therefore it does not appear in the equilibrium constant ,so adding or removing solid has no effect. So According to Le Chatelet's Principle the amount of solid reactant or product present does not have an impact on the equilibrium

What is  Le Chatelet's Principle ?

The position of the equilibrium in a chemical reaction can be predicted with the aid of Le Chatelet's Principle in response to changes in temperature, concentration, or pressure. This is crucial, especially for industrial applications where it's crucial to predict and maximize yields.

According to Le Châtelet's principle, if a dynamic equilibrium is upset by changing the conditions, the equilibrium position will move to compensate for the change and restore the equilibrium.
