If the pendulum is taken into the orbiting space station what will happen to the bob?
a. it will continue to oscillate in a vertical plane with the same period.
b. it will no longer oscillate because there is no gravity in space.
c. it will no longer oscillate because both the pendulum and the point to which it is attached are in free fall.
d. it will oscillate much faster with a period that approaches zero.

Option C

Explanation:

The bob of the pendulum, when the pendulum is taken into the orbiting space station will be in free fall as there is no gravity in space and also the point to which it is attached.

The movement of the bob of the pendulum about its mean position is because of its weight due to which it oscillates and in the free fall, no force acts on it due to its weight since the body is not under the attraction force due to gravity thus it experiences weightlessness and does not oscillate.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

overcharge is the right answer system
