Answer:
1404 m
Explanation:
Given that
Depth of ocean = 780 fathoms
Given that
1 fathoms = 1.8 metes
1 fathoms = 1.8 m
Therefore 780 fathoms
1 x 780 fathoms = 1.8 x 780 m
780 fathoms = 1.8 x 780 m
780 fathoms = 1404 m
Therefore the depth of the ocean in meters will be 1404 m.
Note- A fathom is a unit of length equal to 6 feet (1.828 m) in the imperial and U.S. customary systems, especially used to measure water depth in the ocean. In such an imperial fathom there are two yards (6 feet).
1 gram is greater. 230 miligrams is equal to .230 grams
Answer:
4.91 x 10⁻⁷ m
Explanation:
the applicable formula is
v = fλ
where
v = velocity (i.e speed) = given as 3.0 x 10⁸ m/s
f = frequency = given asw 6.11 x 10¹⁴
λ = wavelength
if we rearrange the equation and substitute the values given above,
v = fλ
λ = v/f
= 3.0 x 10⁸ / 6.11 x 10¹⁴
= 4.91 x 10⁻⁷ m
