7.5.1 A metal spring is made of a certain material. Mass pieces of different magnitudes are attached
to the spring to see how much it will stretch as shown below. If the elastic limit is reached at
14 cm on the meter rule, what will we see when another mass piece is added? (2

Answer #1

Up until the elastic limit, the force we apply externally through the masses will be proportional to the deformation force.

If after the elastic limit,we apply another mass

The deformation force tends increase exponentially, which happens vecabeb the speosp loses its elastic properties like the spring stops coming back to its original shape and the deformations become permanent.

This usual alters the local structural orientation of the spring's material,bringing a change in its properties like a weaker overall resustanre,change is spring constant k and less backwards force.

    Differential Equation problem We know that a force of 2.8 Newtons is required to stretch a certain spring 0.7 meters beyond its natural length. A 1.44-kg mass is attached to this spring and allowed to come to equilibrium. The mass-spring system is then set in motion by applying a push in the upward direction that gives the mass an initial velocity of 1.04 meters per second. Let y(t) represent the displacement of the mass above the equilibrium position t seconds...

    I need help solving for the charge “q”. My professor says it’s just algebra but it seems to be challenging. I added photos of the lab and a free body diagram for reference. Estimating the Charge on a Simple Electroscope Questions one poses to nature in physics are answered through measurement and modeling. The answer has uncertainties not only due to measurements, but how good the model is. This lab is constructed not as a cookbook exercise, but to mimic...
