Answer:
d. displacement
Explanation:
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Answer:
b.) All these technologies use radio waves, including high-frequency microwaves
d.) Microwave ovens emit in the same frequency band as some wireless Internet devices.
e.) The radiation emitted by wireless Internet devices has the shortest wavelength of all the technologies listed above.
f.) All these technologies emit waves with a wavelength in the range of 0.10 to 10.0 m.
Explanation:
For option D. The frequency range of microwave ovens is 2450 MHz = 2.4 GHz, which intersects with wireless internet technology with range of 2.4 to 2.6 GHz.
For E, wavelenght and frequency are inversely proportional. Wireless internet service has the greatest frequency band and hence the shortest wavelenght band.
For F, in all these radiations, the highest Freq is 2.6 GHz and the lowest is 40 MHz. Wavelenght is speed of light (3x10^8 m/s) divided by the frequency.
2.6 GHz = 2.6x10^9 Hz
Wavelenght = 3x10^8 ÷ 2.6x10^9 = 0.1 m
40 MHz = 40x10^6
Wavelenght = 3x10^8 ÷ 40x10^6 = 7.5 m
Velocity is the speed of something in a given direction
The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left. The exception is with low pressure systems. ... This happens simply because the Earth is a sphere and would be true if the Earth didn't rotate.
162.3 meters
Draw a diagram for the problem. You will
have a right triangle with a base of 75.0 m and an angle of 65.0
degrees. You want the opposite side of the triangle x. Using the law of
tangents, you have the following
x/75.0 = tan(65)
x = 75.0 * tan(65)
x = 75.0 * 2.144507
x = 160.8 meters
So now you know that the rocket went 160.8 meters above your eye. But
your eye isn't at ground level, it's 1.50 meters higher. So add 1.50
meters to the 160.8, giving you 162.3 meters.
