The threshold wavelength for emission of electrons from a surface is the minimum wavelength required for electrons to be ejected from that surface. This threshold wavelength is determined by the work function of the material, which is the amount of energy required to remove an electron from the surface.
In this problem, the threshold wavelength is given as 350 nm. When the wavelength is changed to 280 nm, the energy of the incident photons increases and exceeds the work function, causing electrons to be ejected from the surface. The maximum kinetic energy of these ejected electrons can be calculated using the equation:
KE = hf - Φ
where KE is the maximum kinetic energy of the ejected electrons, h is Planck's constant, f is the frequency of the incident photons, and Φ is the work function.
To calculate the maximum kinetic energy for the wavelength of 280 nm, we need to first convert the wavelength to frequency using the equation:
f = c/λ
where c is the speed of light and λ is the wavelength. Substituting the given values, we get:
f = c/280 nm = (3 x 10^8 m/s)/(280 x 10^-9 m) = 1.07 x 10^15 Hz
Now, we can use the equation for maximum kinetic energy to calculate the value:
KE = hf - Φ = (6.63 x 10^-34 J.s) x (1.07 x 10^15 Hz) - (4.35 x 10^-19 J) = 0.88 eV

Therefore, the maximum kinetic energy of ejected electrons for the wavelength of 280 nm is 0.88 eV.
When the wavelength is changed to 360 nm, the energy of the incident photons decreases and is less than the work function. This means that no electrons will be ejected from the surface and the maximum kinetic energy of ejected electrons will be zero.

Under the Commerce Clause, it is possible for California to tax wine imports from Canada without any
concern regarding whether this tax conflicts with federal law.
True
False
Answer:
False
Explanation:
The answer is False. Under the Commerce Clause of the US Constitution, which gives the federal government the power to regulate commerce among the states, it may be possible for California to tax wine imports from Canada, but the tax must not conflict with federal law. In other words, if the tax would put Canadian wine imports at a disadvantage compared to domestic wine, it could be considered unconstitutional. To avoid this, California would need to ensure that its tax applies to both domestic and foreign wines in the same way.

Andrew decided to start his own transportation and touring service for travelers. To accomplish his goal, he needed to purchase a small commuter plane. He only had one problem-money.
Andrew telephoned his very wealthy uncle in Seattle to see if he would like a piece of the action.

In your own words, explain Supply and Demand. In Assignment 1: Scarcity and Choice you are given an example of the supply and demand of PlayStation 2. Think about your life and then provide one example of your own of Supply and Demand.
RESPOND IN 5 SENTENCES !
Supply and demand is the fundamental concept of economics that explains how prices are determined in a market economy. The law of supply and demand states that the price of a good or service is determined by the intersection of the quantity supplied and the quantity demanded. When the quantity supplied is greater than the quantity demanded, the price will decrease, and when the quantity supplied is less than the quantity demanded, the price will increase. In my own example, during the holiday season, the demand for certain gifts such as toys, electronics, and clothing increases, while the supply remains the same, therefore prices tend to increase, and you can find some goods out of stock. Another example can be during a pandemic where the demand for masks and hand sanitizers increases while the supply is limited, prices tend to increase.
How does the Fed cause a recession?
It is possible for the economy to enter a recession if the Fed raises rates too rapidly and recession. For both individuals and companies, higher interest rates make the debt more expensive and borrowing more difficult.
The Federal Reserve, sometimes known as the "Fed," is the nation's central bank and is in charge of carrying out monetary policy. The Fed utilizes interest rate setting as one of its instruments to carry out its policy objectives.
Borrowing may become more costly when the Fed raises interest rates, which might slow down economic growth and perhaps trigger a recession. On the other hand, when the Fed reduces interest rates, it may assist to boost the economy and maybe avert a recession.
The Fed's interest rate decisions can have a variety of effects on the economy and even lead to a recession. For instance, if the Fed raises interest rates too rapidly or to an excessive level, it may increase the cost of borrowing for individuals and firms, which may result in a decline in spending and investment.
