Concept explainers

Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest.

Questions deal specifically with hydrogen.As discussed in the video, so long as you’re using the constants from the PRC, these answers shouldtechnically have an infinite number of significant figures by the assumptions of the course. Report allof them to at least four significant figures to ensure full credit. As always, unless otherwise stated,numerical entry problems require the answer to be in units that are the SI standard for whateverquantity they’re measuring (lengths, for instance, are reported in m, notnm,μm, km, etc.). Convert tostandard units if necessary, but do not include the unit in the answer field.Remember that the way you can be positive Blackboard understands your numbers, if you choose towrite them in scientific notation, is to use “E” in place of “10^.” That is, if you find that a particularfrequency is1.234×1014Hz, it would be entered as1.234E14 1) Calculate the wavelength of thelight that creates thethird line in the Balmerseries.
