Molecules like dna may be stretched and are well modeled as springs. an optical trap can pull with a maximum force of 11\; fn11fn (femto-newtons) and can stretch a dna molecule by 0.06\; \mu m0.06μm . what is the spring constant of the molecule?

1.8 x 10⁻⁷ N/m

Explanation:

= maximum force with which the optical trap can pull = 11 x 10⁻¹⁵ N

x = stretch caused in DNA molecule due to the force = 0.06 x 10⁻⁶ m

k = spring constant of the spring

Maximum force is given as

k = 1.8 x 10⁻⁷ N/m

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
