Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

I know your only allowed to answer 1 question but these 4 questions build off eachother. If you could please answer all four that would be great. More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino — the antimatter answer to the nearly massless neutrino — collided with an electron, it could produce a cascade of other particles. The "Glashow resonance (Links to an external site.)" phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations. What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)? What is this threshold energy in units of joules? Now consider a baseball with the same kinetic energy as that of the Glashow resonance. What speed in m/s would correspond to this…
