mechanical principles  Examine devices which function to store mechanical energy in their operation.

In the 1970s cartoon The Super Friends, the Wonder Twins helped Superman and others fight crime. One of the Wonder Twins was Zan, who was able to take on the form of H2O in its various phases (ice, liquid water, water vapor). After taking a physics class, he decides to conduct a little experiment by turning into an ice igloo in the park on a hot day. (a) If his total mass as an igloo is 64.50 kg and he starts with a temperature of −13.50°C, how much heat must flow into him to completely melt his body? J(b) He continues absorbing energy up to the point where he would start to vaporize (100.0°C). How much more heat is required to raise his temperature to the vaporization point? J(c) How much more heat is required to turn him into water vapor at 100.0°C? J(d) If we model the water vapor molecules making up his body as having only six degrees of freedom, what is the average kinetic energy of one of the water vapor molecules that make up Zan? (Consider the case when Zan is water vapor at…

Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: ​Q​t​= Q​0​^e​-kt​ where: ○Q​t​ = quantity of radioactive material at time t ○Q​0 ​= original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k   Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?

Solve correctly please.

Ensuring quality in engineering is a very important criterion for judging the efficiency of theoperation. The Ishakawa fishbone diagram is a useful tool for performing an analysis of a fault ordiagnosing poor quality. Identify a simple engineering problem of your choice and use the Ishakawafishbone diagram, to identify the immediate and remote causes of this problem.

True or false

NUMBER ONE: Applications of thermodynamics in mechanical engineering, draw and briefly explain one application. Include in the brief discussion how that system works; what processes are involved in its processes; and what are its benefits to modern society.

During lab, Table Group 9 accidentally launches their spring from the tabletop onto the light fixture shown in the diagram. The spring has a mass of 12 grams. The instructor gave clear instructions not to stretch the spring by more than 70 cm to protect it from damage. If this spring's stiffness is k= 15 N/m, did the group follow instructions or did they stretch the spring too far? 3.0 m 1.2 m
