Answer: e. on the equator and in the Atlantic Ocean
Explanation:
Latitude and Longitude are geographical coordinates.
<u>Latitude</u> is the angular distance between the <u>equatorial line</u>, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.
In this sense latitude refers to the equatorial line that divides the Earth in two hemispheres (North and South).
On the other hand, <u>Longitude</u> represents the specific <u>east–west </u>position of a point on the Earth's surface, being longitude the prime meridian or Greenwich meridian.
So, if we have latitude and longitude
(positive means it is to the East) we can already know the point is in the equator, and the option that bests describes the coordinates is e.
The most important thing you should remember in order to get how is its linear momentum relative to the surface is that the<span> point on the circumference is moving at w rad/second.
Therefore, here is the solving formulae:
if </span>
you can easily get <span> linear momentum p :
</span>
I'm sure that helps.
Therefore, here is the solving formulae:

A) 0.136 - 0.158 m
B) Microwaves
Explanation:
A)
For an ectromagnetic wave, there is a relationship between its frequency and its wavelength, contained in the wave equation:
where
is the wavelength of the wave
is the speed of light in a vacuum
f is the frequency of the wave
For the waves in this problem, we have:
is the minimum frequency
is the maximum frequency
Therefore, the range of corresponding wavelengths is:
B)
Electromagnetic waves are oscillations of the electric and the magnetic field occurring in a plane perpendicular to the direction of motion the wave.
All electromagnetic waves travel in a vacuum always at the same speed, the speed of light (
).
Electromagnetic waves are classified into 7 different types, according to their wavelength and frequency. From the longest to the shortest wavelength, we have:
Radio waves (>1 m)
Microwaves (1 mm - 1 m)
Infrared (750 nm - 1 mm)
Visible light (380 nm - 750 nm)
Ultraviolet (10 nm - 380 nm)
X-rays (0.01 nm - 10 nm)
Gamma rays (<0.01 nm)
Therefore, we see that the waves in this problem (of wavelength between 0.136 and 0.158 m) are classified as microwaves.
