A student is designing an experiment on force and motion. The student has 3 tables with the same wood surface, 3 blocks made of the same material, but different mass (100 gram, 200 gram, and 300 gram). The student is pulling the block across the table using a spring scale. What do you think the student is testing in this experiment. Type the QUESTION you think is being asked/tested in this experiment.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

The energy of a photon is equal to (what) times (what) of the photon.

In a house all the electrical wires run back to either a bank or a blank
