Answer:
1.7 J
Explanation:
The energy carried by a single photon is given by
E=hf
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of f=1.7 \cdot 10^{17} Hz, therefore its energy is
E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J
I think the answer is b. compaction
The restoring force in a simple harmonic oscillator acts as a restoring force, acting opposite in direction of and proportional in magnitude to the displacement. This has the result that when the oscillator reaches the equilibrium point, it has gained its maximum kinetic energy (and therefore velocity) while the magnitude of the restoring force, and therefore the acceleration, is 0.
Choice A
The statement that "Income only includes salary " is not true.
Income is the money that an individual or organization<u> </u>receives in return for their services or goods.
Depending on the context—such as taxation, financial accounting, or economic analysis—income may have a variety of definitions.
For the majority of people, their total earnings include their wages and salaries, investment returns, pension payments, and other receipts.
For businesses, income refers to the money made from<u> selling goods and services as well as any interest or dividends paid </u>on the company's cash holdings and reserves.
So, the amount of money, property, and other value transfers received over a predetermined period in return for goods or services is often referred to as "income."
That's why income does not include only salary.
Hence Statement (D) about the income is not true.
