Spring force is proportional to stretch distance, F=kd. Work done while stretching a spring is proportional to the force times the distance. How do you expect the work to compare if you stretch twice as far? same
double
four times

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

Why does gravity have a lesser than grater effect on higher altitudes?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
