How much energy does a wave with a frequency of 3.78 x 1010 Hz have?

Answers

Answer 1

The energy of the wave of frequency 3.78×10¹⁰ Hz is 2.5×10⁻²³ J.

What is energy?

Energy is the ability or the capacity to perform work.

To calculate the energy of the wave, we use the formula below.

Formula:

E = hf......... Equation 1

Where:

E = Energy of the waveh = Planck's constantf = Frequency of the wave

From the question,

Given:

f = 3.78×10¹⁰ Hzh = 6.63×10⁻³⁴ J/Hz

Substitute these values into equation 1

E = 3.78×10¹⁰×6.63×10⁻³⁴ E = 2.5×10⁻²³ J

Hence, the energy of the wave is 2.5×10⁻²³ J.

If the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

This problem can be solved by using the concept of Ideal gas equation.

What ia ideal gas equation?

The equation of ideal gas can be expressed as

PV = nRT

where,

P is the pressure of the gas

V is the volume taken

n is the number of moles of the gas

R is the gas constant = 6.314 J/ mol K

T is the temperature

Now from given data, we have the values of

V = 3.2 L

P = 5.5 atm

T = 53°C = 273 + 53 = 326 K

By substituting all the values, we get the value of n

3.2 × 5.5 = n × 6.314 × 326

17.6 = n × 2058.36

n = 17.6 / 2058.36

n = 0.0085 mol

Now, we have to find the temperature

n = 0.0085 mol

V = 2.6 L

P = 3.2 atm

By substituting all the values, we get

3.2 × 2.6 = 0.0085 × 6.314 × T

8.32 = 0.053 T

T = 8.32/ 0.053

T = 156.98 K

Thus, we concluded that if the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

explain the three forces at work that hold an atom together

Answers

An atom is held together by three forces: the strong nuclear force, the electromagnetic force, and the weak nuclear force.

The strong nuclear force is the strongest of the three forces and is responsible for binding the protons and neutrons together in the nucleus of an atom. The strong nuclear force is a short-range force that acts only over a very small distance, and it is strong enough to overcome the repulsive forces between the protons, which are positively charged particles.

The electromagnetic force is the second strongest of the three forces, and it is responsible for binding the electrons to the nucleus of an atom. The electromagnetic force is a long-range force that acts over a larger distance than the strong nuclear force, and it is caused by the attraction between opposite charges (positive and negative).

The weak nuclear force is the weakest of the three forces, and it is responsible for certain types of radioactive decay, such as beta decay. The weak nuclear force is a short-range force that acts only over a very small distance, and it is much weaker than the strong nuclear force and the electromagnetic force.

Overall, the three forces at work that hold an atom together are the strong nuclear force, the electromagnetic force, and the weak nuclear force. These forces act at different ranges and with different strengths, but they all play a crucial role in maintaining the stability and integrity of an atom.

What are Redox Reactions?An electron transfer between two reactants that are involved in a chemical reaction is known as a redox reaction. Observing variations in the oxidation states of the reacting species will help you spot this transfer of electrons.Below is an illustration of a redox reaction showing the transport of electrons between two reactants.As seen in the image below, reactant A underwent an oxidation reaction after losing an electron, which is the reactant. Similar to reactant A, reactant B also received an electron, resulting in reduction.Oxidation is the process of a given reactant losing electrons and changing from a reduced to a more oxidized state. Reduction is the process of adding electrons to a reactant and causing it to become less oxidised.The term "oxidizing agents" refers to electron-accepting species that have a tendency to reduce redox processes. A reducing agent is an electron-donating substance that typically gives away electrons. Oxidation is a common process for these species.

A two digit number is such that sum of the ones and tens digit is 10.If the digits are reversed, the new number formed exceeds the original number by 54. Find the new number The sides of a hexagon are 2, 3, 2, 4, 7, and 6. Find the perimeter of a similar hexagonwith two sides of length 3. Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse? What is the additive inverse of that elevation? What effect does using arrange instead of one of its synonyms have on the play? Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. Theobject moves with constant acceleration. Which part of a velocity vs. time graph can be used to calculate thedisplacement of the object? A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mille. The boat is launched from the point (7,0) and goes to point (7.-7) to fish. From there, the boattravels to (0, -7) to fish and then goes back to the launch point.Determine the total number of miles traveled. Round to the nearest whole number.10 miles12 miles14 miles24 miles the timing of a mutation during development has negligible effects on the severity of the genetic defect. 5. Through which layer(s) does light energy travel to reach the palisade mesophyll? what happens when harriet tells dr. flint that a free man loves her and she wants to be married to him? Ms. Bobadilla has a 24 ounce coffee. I drink 8 ounces. What percent of the coffee is left? 7th grade math what is the equation for the function (2,44) and (5,80) what type of b cell does not secrete many antibodies during a primary immune response, but is very important for a secondary immune response? Scenario A. Courtney and Wayne are managers in a medium-sized retail store. They have been notified by their district office (just as the extremely busy holiday season is beginning!) that there are several significant changes about to take place in their organization. While neither Courtney nor Wayne is enthusiastic about the changes, their reasons for "fighting back," as they put it, are different. Courtney believes that she might agree with the organization's ideas but hasn't seen enough information and would like to wait to meet and discuss the change before deciding. Wayne, on the other hand, sees no future in the change and doesn't believe that he will ever agree with the organization's idea. Wayne has a long history of disagreeing with "corporate." In fact, no one that works with Wayne can remember a single change that he has not challenged. Courtney and Wayne are both exhibiting
