Hegelich a particle undergoes two displacements. the first has a magnitude of 163 cm and makes an angle of 128 ◦ with the positive x axis. the resultant displacement has a magnitude of 176 cm and is directed at an angle of 36.8 ◦ to the positive x axis. find the magnitude of the second displacement. answer in units of cm

Explanation:

First displacement is given as

= 163 cm at 128 degree

so we have

Now the resultant displacement is given as

= 176 cm at 36.8 degree

so we have

now we know that

so magnitude of the above displacement is given as

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 .
