Greta bought her friend Elijah a 20-ounce cup of gourmet coffee at the mall. After Elijah takes a sip, he discovers that it does not have the ingredients he had hoped for, although he had told Greta what he wanted. Which action should Elijah take in this situation? Assume that the coffee is nonrefundable.

The correct action that Elijah should take in this situation is to thank Greta for the cup of coffee and try to enjoy it. This would be the most polite, friendliest option, also the most socially acceptable way to deal with the situation. He could have responded in one of the other ways which would be rude and impolite and show that he is not a good friend. If he values his friendship with Greta he will just be thankful for the coffee.

It depends, if he wants his coffee sweeter then add sugar or if he wants cream add cream. if it is too sweet and he wants it stronger then he should go to the place where Greta got the coffee and ask for extra shots. If the coffee is entirely wrong tell the emplo

Options:
a. a lower frequency and a shorter wavelength.
b. a higher frequency and a longer wavelength.
c. a lower frequency and a longer wavelength.
d. a higher frequency and a shorter wavelength

Answer:
d. a higher frequency and a shorter wavelength

Explanation:
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
For example, Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

a. a lower frequency and a shorter wavelength.
b. a higher frequency and a longer wavelen

Answer: Option B and C are True.

Explanation:
The weight of the two blocks acts downwards.
Let the weight of the two blocks be W. Solving for T₁ and T₂:
w = T₁/cos 60° -----(1);
w = T₂/cos 30° ----(2);
equating (1) and (2)
T₁/cos 60° = T₂/cos 30°;
T₁ cos 30° = T₂ cos 60°;
T₂/T₁ = cos 30°/cos 60°;
T₂/T₁ =1.73.
Therefore, option a is false since T₂ > T₁.
Option B is true since T₁ cos 30° = T₂ cos 60°.
Option C is true because the T₃ is due to the weight of the two blocks while T₄ is only due to one block.
Option D is wrong because T₁ + T₂ > T₃ by simple summation of the two forces, except by vector addition.
Answer: Option B and C are True.

Explanation:  
The weight of the two blocks acts downwards.
