g You have a tube that is open at both ends and the fundamental frequency has a wavelength of 0.90 m. You want to make the tube longer and still have that wavelength as one of the harmonics, but you want to lengthen it as little as possible. How much longer should you make it

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

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 .
