I think it’s C. Stroke if not then D
Answer:less
Explanation:thats the answer
Its C because if it is a low frequency it will not change much so it will be a longer wavelength and the higher the frequency the shorter the wavelength
Below are the choices that can be found elsewhere:
A. (4.9 × 10-14 newtons) · tan(30°)
<span>B. (4.9 × 10-14 newtons) · sin(30°) </span>
<span>C. (4.9 × 10-14 newtons) · cos(30°) </span>
<span>D. (4.9 × 10-14 newtons) · arctan(30°) </span>
<span>E. (4.9 × 10-14 newtons) · arccos(30°)
</span>
<span>Force is proportional to the angle made by the velocity with respect to the magnetic field. It is maximum when velocity is perpendicular to the magnetic field and minimum when the velocity is parallel to the magnetic field. It is proportional to sin of the angle. In this problem it will be proportional to sin(30)</span>
Answer:
(I) meteorite is usually covered with a dark crust from burning in Earth's atmosphere.
(II) A meteorite usually has a high metal content.
(III) Meteorites when compared to terrestrial rocks have different isotope ratios of particular elements.
(IV) Meteorites contain rare elements, such as iridium, that terrestrial rocks do not contain.
