Explanation:
The scenario is shown in the image attached below. A Right Angled Triangle is formed. We have an angle of 6 degrees, the side adjacent to angle which measures 1 mile and we need to find the side opposite to the angle.
Since 1 mile = 5280 feet, the side adjacent to the angle has a measure of 5280 feet.
Tangent ratio relates the opposite and adjacent side by following formula:
Using the given values, we get:
Thus, rounded to nearest foot, the height of the building is 555 feet
Answer:
4.79 J
Explanation:
The energy of a single photon is given by
where
is the Planck constant
f is the frequency of the photon
Here we have
so the energy of one photon is
Here we have 1 mol of photons, which contains
photons (Avogadro number). So, the total energy of this mole of photons is:
