The polarized glasses contain a special filter that blocks the glares and the hazes while driving through the sun or looking at the water, which makes your eyes more comfortable and makes you see better.
Hope this Helps! :)
-- Since it's a cube, its length, width, and height are all the same 4 cm .
-- Its volume is (length x width x height) = 64 cm³ .
-- Density = (mass) / (volume)
= (176 g) / (64 cm³)
= 2.75 gm/cm³ .
100/1=x/0.985, 98.5=x. So the distance from Orlando is 220-98.5=121.5miif he adjusts, he has 98.5 miles more to do, plus 121.5 miles he already did, the flight is 1.25 mi farther
The unit of frequency, kHz, is also equivalent to 1/kilosecond or 1/1000 seconds. The equation relating wavelength and frequency is:
c = wavelength*frequency, where c is known as the speed of light. But since we are dealing with ultrasound, we use the speed of sound. The speed of sound is dependent on the temperature. The correlation would be:
c = 331 + 0.6T = 331 + 0.6(20°C) = 343 m/s
Therefore,
343 = wavelength * 1/1000
wavelength = 343,000 meters
