Aforce of 10 n stretches a particular spring by 2 cm. how far would a 20 n force stretch that same spring? a force of 10 n stretches a particular spring by 2 cm. how far would a 20 n force stretch that same spring?
a. 20 cm
b. 4 cm
c. 8 cm
d. 2 cm

Explanation:

Given that,

Force acting on the spring,

Stretching in the spring,

Force acting on the spring,

Stretching in the spring,

To find :

How far would a 20 N force stretch that same spring?

Solution,

For the same spring, the value of spring constant must be same. The relation between the force and the spring constant is given by Hooke's law as :

F=kx

Hence, the 20 N force stretch by 4 cm.  

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

temp rises, and expansion
