Answer:
8000 kg/cm^3
Explanation:
The density formula is P = M/V
Density = P = ? expressed in kg/m^3
M = mass = 40,000 kg
V = volume = 5 m^3
P = 40,000/5
P = 8000 kg/m^3
Lol .. a what - a wave ? You just greeting somebody basically when your waving at someone I don’t really get the question but :) help it’s okay !
Answer:
Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.
Sadly, we're forced to answer the question without the benefit of the
list of choices, which, for some reason, you decided not to let us see.
Index of refraction of a substance =
(speed of light in vacuum) / (speed of light in the substance).
Any number greater than ' 1 ' can be an index of refraction. A number
less than ' 1 ' can't be . . . that would be saying that the speed of light
in this substance is greater than the speed of light in vacuum.
