Determine whether each of the following situations involves linear motion, rotational motion or a combination of the two: a)a baseball dropped from the roof of a house.

b)a baseball rolling toward third base

c)a door swinging

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 .

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
