Weight is best descried as? a. the interval between two events b. a measure of gravitational force on an object c. the amount of matter in an object d. the amount of surface included within a set of boundaries

Weight is best described as:

B.a measure of gravitational force on an object.

Explanation:

The force with which an object is attracted by any celestial body is called   the weight of the body.Since, Force = Mass × Acceleration

           Weight= Mass × Acceleration due to Gravity(g)

The gravitational force exerted by a body greatly depends on the mass of the body.Greater the mass greater is the weight.Gravity of a body with Greater mass will be more therefore the weight of a body varies from place to place and on different celestial bodies.For example, The mass of the Earth is six times greater than the moon and thus a body  moon weighs one-sixth of its weight on Earth.

         Here the mass of the body is a constant quantity and thus the acceleration due to gravity differs.

In some developing nations the percentage of the animal protein from fish in the diet can be as high as 25 percent.  about 85% of fish caught is used for human consumption.  the remainder is converted into fishmeal and fish oil.
