Aspring is stretched from x=0 to x=d, where x=0 is the equilibrium position of the spring. it is then compressed from x=0 to x=−d. what can be said about the energy required to stretch or compress the spring? view available hint(s) a spring is stretched from to , where is the equilibrium position of the spring. it is then compressed from to . what can be said about the energy required to stretch or compress the spring? more energy is required to stretch the spring than to compress it. the same amount of energy is required to either stretch or compress the spring. less energy is required to stretch the spring than to compress it.

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.

Ablock of steel has a density of 0.29lbs per cubic inch. if the block has dimensions of 1 inch by 1 inch by 3 inches, what is its weight? a. 0.29lbs b. 0.58lbs c. 0.87lbs d. 1lbs

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
