1. When you a place a rubber loose rubber band in contact with your lip, you notice a slight increase in temperature when the rubber band is stretched. a) Is work being done by the rubber band or is work being done on the rubber? b) Since there is not any heat added or removed from the rubber band what type of thermodynamic process can you say this is? c) Using the first law of thermodynamics and your answers to...

Consider the following observation: A rubber band is stretched under tension (at least 0.5 cm wide) and then touched to the Upper lip and found to be warm. Then the rubber band is relaxed and stretched a second time and held under tension for several seconds. The rubber band is relaxed and touched to the upper lip and found to have a cooling effect. Analyze these two observation using delta G = Delta H - T delta S for the...

Consider a stretched rubber band where experimental observations show that the tension f is proportional to temperature T if length L is held constant. Show that 1) The internal energy U is only a function of temperature. 2) adiabatic stretching of the band results in an increase in temperature. 3) the band will contract if warmed while kept under constant tension.

You are attempting to determine the spring constant of a rubber band. To do this you hang an 82 N weight from the rubber band and measure its length to be 0.62 m. You then hang a 195 N weight from it and measure the length to be 0.87 m. Now you can calculate the spring constant of the rubber band. What is it?

Conservation of Energy 1 Slingshot /Catapult An ordinary rubber band, similar to the ones we used in lab, has a spring constant of 90 N/m The rubber band is used to launch a small stone. Suppose the rubber band is extended 10 cm beyond its rest position when the stone is launched, and assume that the mass of the stone is 5 g (a) Find the force needed to stretch the rubber band to 10 cm (b) Assuming that all...

A ball of mass m is connected to one end of a rubber band and swung in a circle. The rubber band has spring constant k, and its unstretched length is r0. If it is swung at an angular velocity ω, to what length will it stretch the rubber band? Please use energy if you can !! I started to try it using spring potential = rotational kinetic and used I = mr^2 for moment of inertia. but if i...

a) Based on the best-fit analysis, estimate the proportionality constant k for the rubber band. b) How many coins are necessary to stretch the elastic band by one metre? Would this be possible with the rubber band I used in this expirement? Based on the data I obtained from my Hooke's Law experiment, I created a graph (which was linear) and determined the best-fit equation based on my graph: y = 11.445x + 0 Please note, the weight of one...

Work is being done to stretch the packing tape. The force of the rubber band is modeled with an expression F (x) = - Fo [(L + x)/L − L2 /(L + x)2], where Fo = 9.2 N, the elastic length of the elastic band L = 0.95 m and the x is the change in the length of the elastic band. Determine how much work is done on the elastic band when stretching the distance d = 0.55 m

S6. Remember Horatio? Once you convinced him that he should not apply for the Nobel Prize, he turned his attention to his hobby of stretching rubber bands. One day he accidentally touched a freshly stretched rubber band to his cleanly shaven face (Horatio, believed in obeying the dress and grooming code) and observed that heat was being evolved when the band was stretched. Excited by this discovery he raced to the lab and performed the following experiments. (1) A rubber...

If you were to replace a string on your guitar with a thicker string but put it under the same amount of tension, would the wave speed change? Select one: Yes, the wave speed would decrease. Yes, the wave speed would increase. No, the wave speed would stay the same because it is under the same tension. O Check When you increase the driving frequency of a wave on the string does the wavelength decrease, increase, or stay the same?...
