Aspring that is stretched 23 cm from its equilibrium point experiences a force of 103 n. a.) how much energy is stored in the spring?

U = 11.85 J

Explanation:

given,

spring is stretched = 23 cm

                             x = 0.23 m

Force experiences = 103 N

we know,

 F = k x

where k is the spring constant

       k = 447.83 N/m

energy stored in the spring

        U = 11.85 J

hence, energy stored in the spring is equal to U = 11.85 J

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
