Find the relationship for how the temperature distribution changes with time with respect the un-deformed rod and the deforming rod.
Lets say you were interest in looking at temperature distribution as a rod deforms. You have found the point map for the rod: x = (1 + t)X As well as the distribution of temperature in the Lagrangian description. T = Xt^2 Find the relationship for how the temperature distribution changes with time with respect […]
What direction are the ocean currents moving near Miami?
Access the following link https://earth.nullschool.net/#current/wind/surface/level/equirectangular=-80.83,26.64,165/loc=-85.593,24.567 The visualization shows the current surface-level winds. You can change the visualization by clicking on βearthβ at the bottom left corner of the screen. Answer the following questions by zooming into Miami by using the scroll button of your mouse: What is the direction of winds over Miami? Include a […]
Hypotheses should make specific, testable predictions and are often in IF-THEN form, e.g., “if x is changed, then y will occur.”
Topic: Temperature and Heat Physics Experiment Report Format Hypothesis Hypotheses should make specific, testable predictions and are often in IF-THEN form, e.g., “if x is changed, then y will occur.” A hypothesis answers the question, “What is the point of the experiment”? Write a paragraph describing the approach or strategy used to test the hypothesis. […]
What is the maximum temperature? and at what reactor volume is the temperature maximum?Vary some of parameters e.g. the ratio of A to inerts, and/or inlet temperature, explain the changes in the temperature in molar flow rates of A,B, C versus the reactor volume.

Determine the temperature and the pressure at the triple point.Calculate the latent heat of sublimation and vaporization for this substance. Finally, determine, in the triple point, the corresponding latent heat of fusion.
1) Reduce the partial derivative (πΞΌππ)π. The answer must be in terms of the thermodynamic properties πΌ,πππππππ. 2) A particular system, containing 1 mol, is taken from state A to state B through a process that obeys ππ£1/2=ππππ π‘.Knowing that during this process πΌ=ππβ1, ππ=πand ππ=ππ£2are known and π,π,πare positive constants, determine the temperature variation of […]
What are some examples, other than temperature, where similar averages can be associated with very different distributions?Discuss
What are some examples, other than temperature, where similar averages can be associated with very different distributions? A few thoughts: costs (e.g., cost of illegally downloading a song online is the same average cost of driving above the speed limit, assuming that you are only caught speeding occasionally); ERA of pitchers (i.e., some are very […]
The variables y and t satisfy the differential equation Ti1 = (y + 2)sin2t. Also, when t = 0,y = 0. Find the exact value ofy when t = 714. You must use calculus and give the results of any integration needed to solve this problem (e) The diagram shows how the curve y = ex intersects with the curve y = kx0.5 + 1 when k = 4 and k = 5. Find the area of the space between y = ex and y = kx0-5 + 1, when the x-coordinates of the points of intersection are 0 and 2.

What is the importance of knowing the melting point of a natural compound after extraction?
What is the importance of knowing the melting point of a natural compound after extraction? Below are the results you got from your experiment (Caffein extraction from tea leaves). The melting point of caffeine was reported to be around 238 Β°C in literature. Discuss the reason(s) for getting higher or lower melting point than 238 […]
