- fill the table take any data and show calculation for that data which you chooseSuppose we put an object with temperature T0 in a room with constant temperature K.We know that the heating/cooling speed of the object is proportional to the temperature differencebetween the object and the environment with ratio r a positive constant. If we write the temperature of the object T as a function of time t, write out the differentialequation it has to satisfy.And if they also indicate us as data that Φ = 0.490. How does the result change?
- Computers are not supposed to be in very warm rooms. The highest temperature tolerated for maximum performance is 308 K. Express this temperature in C and F.If the ni values are all the same, a shorthand way of indicating a combination is C(x,y), which is read, How many combinations are there of x distinguishable objects separated into systems, each of which have y things? Evaluate a C(10,2) b C(3,1) c C(6,3) d C(6,2). Hint:You should determine the number of systems you need for each case first.Please use the following data to create a scatter graph with smooth lines and markers to connect and indicate the data points.
