<span>First of all, an ounce of hard liquor (gin, vodka,
rum, whiskey, or scotch) contains 64 calories for 80 proof varieties,
and 80 calories for those that are100 proof. The proof refers to the
percentage of alcohol in the liquor (80 proof is 40 percent alcohol; 100 proof is 50 percent alcohol)</span>
Answer:
0.47m²
Explanation:
Given parameters:
Length = 9.025 x 10⁶m
Width = 5.215 x 10⁻⁸m
Unknown:
Area of the rectangle = ?
Solution:
Area is the derived from the product of the length and width of a body.
Area = length x width = 9.025 x 10⁶m x 5.215 x 10⁻⁸m
Area = 0.47m²
True, they are non-metal
And it's metal, not mental XD
The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.
Given the wavelength of the yellow light (700 nm. in this case) we can find the frequency
<span>by dividing the speed of light c by the wavelength w, that is: f = c/w and we know that </span>
<span>c is equal to 2.998 * 10**8 meters per second. </span>
<span>So the frequency f = (2.998 * 10**8) / (7.0 * 10**-7) = 4.283 * 10**14 cycles per sec. </span>
<span>(or Hz.) Since the threshold frequency of Cs is 9.39 * 10**14 Hz, the red light doesn't </span>
<span>have a high enough frequency (or energy) to cause electron emission. </span>
<span>Hope this answers your question.</span>
