4. Calculate the energy (E) and wavelength (1) of a photon of light with a frequency of
6.165 x 1014 Hz.
PLEASE HELP!!
Answers
Answer: E= 4.085 x 10^-19 J ; Wavelength= 4.862 x 10^-7 m
Explanation:
Sorry for the messy work, but I hope this helps.
Remember:
Plancks constant (h)= 6.626x10^-34 Js
Speed of light (c) = 2.998 x 10^8 ms^-1
What I did:
I found the energy first with the given frequency. Don't forget to convert your units to s^-1! They are actually the same, you dont need to do math for that conversion, just a simple Hz to s^-1.
For the wavelength, I multiplied plancks constant (h) and speed of light (c) together. With that number I divided by the energy found which 4.085 x 10^-19J. Also, be sure to cross off the units because it can get very confusing.
The energy of the photon is 4.08 x 10⁻¹⁹ J
The wavelength of the photon is 2.58 x 10⁻⁶ m
The given parameters;
frequency of the photon, f = 6.165 x 10¹⁴ Hz
The energy of the photon is calculated as;
E = hf
where;
h is Planck's constant = 6.626 x 10⁻³⁴ Js
E = (6.626 x 10⁻³⁴)( 6.165 x 10¹⁴)
E = 4.08 x 10⁻¹⁹ J
The wavelength of the photon is calculated as;
v = fλ
where;
v is the speed of light = 3 x 10⁸ m/s
[tex]\lambda = \frac{v}{f} \\\\\lambda = \frac{3\times 10^8}{1.165\times 10^{14}} \\\\\lambda = 2.58 \times 10^{-6} \ m[/tex]

Hope this helped!
Explanation:
Apart from different ways to classify soils. The one factor that scientists use to classify orders of soil is climate. Hence, Option (B) is correct
What is Climate ?Climate is the long-term pattern of weather in a particular area.
Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year.
A region's weather patterns, usually tracked for at least 30 years, are considered its climate.
Other factors people uses in classifying orders of soil are;
ClimatePlant typeSoil compositionSoil orders are known as the single dominant attributes affecting soils in any location.
They can be the prevalent vegetation such as Alfisols and Mollisols or the type of parent material such as Andisols and Vertisols or the climate variables such as lack of precipitation etc.

The transition metals (with the exception of Zn, Cd and Hg) are very much hard and have low volatility. Why Zn ,Cd and Hg has low melting points. (a) These have all their electrons paired. (b) These have maximum number of unpaired electrons. (c) These have very strong metallic bonding. (d) These have more metal-metal bonding.
Answers
Answer:
Zn ,Cd and Hg has low melting points because - These have all their electrons paired.
Explanation:
These have all their electrons paired -: All the electrons in the d-subshell are combined with Zn , Cd and Hg. The metallic bonds present in them are, therefore, weak. This is why they have low points of melting and bolting. therefore , this statement is true. These have maximum number of unpaired electrons. Since , these transition metals have all electrons paired , so this statement is incorrect.These have very strong metallic bonding -: Zn, Cd and Hg d-orbital are completely filled. They have poor metallic bonding and less compact packing due to their fully filled d-orbitals, so all of them are volatile in nature. Therefore, this statement is also not valid .These have more metal-metal bonding. -: Since , their metallic bond is weak , so this statement is not true .Hence , the correct option is A (These have all their electrons paired).
(4.1357 x 10^-15) x (5.4 x 10^2) Answer must be in scientific notation
Answers
Answer:
22×10⁻¹³
Explanation:
Scientific notation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value. Thus, in given value,
(4.1357× 10⁻¹⁵) × (5.4×10²)
22×10⁻¹³

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.
What is an echolocation ?Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.
(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.
Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.
Thus, option A is correct.

what happens to the molecules as water freezes PLS HELP THIS IS DO TODAY
Answers
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. ... Thus water expands as it freezes, and ice floats atop water.
When water molecule freezes, the water molecules have slowed down enough that their attractions fixed them into fixed positions.
What do you mean by freezing ?The term freezing is defined as a phase transition where a liquid converted into a solid when its temperature is lowered below its freezing point.
The freezing point is the temperature at which a liquid turns solid. In the freezer, for example, water-filled ice cube trays.
Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid. It is worth noting that the molecules in ice would be vibrating.
Thus, When water freezes, the water molecules slow down to the point where their attractions arrange them into fixed positions.

what is the standard form of 12,341 us?
Answers
Answer:
12341 in standard form = 1.2341 × 10⁴
Explanation:
When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.
As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.
As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:
12341 in scientific notation = 1.2341 × 10⁴.
This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.
