Atank of oil has a mass of 50 slugs.
a) determine its weight in pounds and in newtons at the earth’s surface.
b) what would be its mass (in slugs) and its weight (in pounds) if located on the moon’s surface where gravitational attraction is 1/6th that at the earth’s surface?

Answer

given,

mass of oil tank = 50 slugs

a) we know,

   1 slug = 32.2 lb

   50 slug = 32.2 x 50

                 = 1610 lb

  weight in terms of newton

   1 slug = 14.594 Kg

   50 slug = 50 x 14.594

                 = 729.7 kg

   weight = m g

   weight = 729.7 x 9.8

               = 7151.06 N

b) mass of the oil will be same on moon i.e. = 50 slug

   weight of the oil on the moon will be

          = [tex] \dfrac{1}{6}\times 1610

          = 268.33 lb

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
