Solve a problem by designing a device that uses thermal conductors or insulators. You can come up with your own problem to solve (preferred) or work on one of these problems: Campers want a travel cup that uses a cold pack to cool a liquid. Design the outer part of the cup that keeps the drink cold once it has been cooled down.
Campers want a travel cup that can use a cold pack to cool a liquid. Design the inner compartment that holds the cold pack and conducts heat from the liquid in the cup.
People who like to work while sitting on couches or comfy chairs find that laptops are too hot to be held on their laps. Design something for the bottom of a laptop that conducts heat away from the lap and the laptop.
An animal refuge routinely moves turtle eggs to a new location. Typically buried in the ground, the eggs have to be kept at the same temperature as the ground while they’re being moved. Design an insulated container to keep the eggs at the correct temperature.
Storing a cell phone in a cold environment is detrimental to its battery life. Design a “coat” or a container for a cell phone to shield it from cold weather and prolong its battery life.
Describe the device that you plan to design, build, and test. Will your device use thermal conductors or insulators?

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
