A0.650 kg air-track glider is attached to each end of the track by two coil springs. it takes a horizontal force of 0.900 n to displace the glider to a new equilibrium position, x= 0.070 m. find the effective spring constant of the system.

Spring constant will be 12.857 N/m

Explanation:

Horizontal force is given  F = 0.900 N

Displaced in position x = 0.070 m

We have to fond the spring constant

Displacing force is equal to , here K i spring constant

So spring constant

So effective spring constant will be 12.85 N /m

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 .

where’s the list ? the question is incomplete
