During a physics exam, a typical student has a heat output of 280 W. If all of the energy released by 110 physics students is transferred to the 3200 m' of air in the room, how much will the temperature of the air rise during a 50-minute exam? Assume that none of the heat escapes and the air conditioning is off. The specific heat of air is 1020 J/kg K and the density of air is 1.20 kg/m

Problem 1. In the distant future, a physics student is rushing to her final exam traveling in a spaceship at relativistic speed. She passes a policeman at rest a distance 9 km from a traffic signal (measured in his rest frame). a) The policeman monitors the student’s tail lights (red light with λ=650 nm in her rest frame) with a spectroscope, viewing directly along her motion away from him. He observes a wavelength λ=1300 nm (infrared). What is her speed...

Once when teaching this class, I had a student nearly faint during an exam. We moved the student into a back room, and called the paramedics; the student had very altered consciousness, and felt tingling and numbness in their hands and feet. When the paramedics arrived, they had the student breathe into a paper bag for a while. Within minutes, the student felt better. The paramedics thought that the student might have an anxiety disorder, and had (due to nervousness)...

An exam has 5 questions and each of them has 4 possible answers. A student gets 3 points for each correct answer and loses 1 point for each wrong answer. Consider a student who answers all questions completely at random. Let X denote the number of correct answers and Y the number of points of this student at the end of the test. (A negative score is possible). (a) Compute the mean and the standard deviation of Y , µY...

Design a Moore state machine that has an input w and an output z that should output a ‘1’ when the previous 4 values of w were 1001 or 1111. Overlapping patterns are allowed. Show the state diagram and state table. Use a simple binary counting order for the state assignment. Derive all of the next-state and output equations. You do not need to draw the resulting circuit, instead write a Verilog module for it.

calculate the conductive heat flux (W) for the different “feather” materials. Material “A” has a K of 0.036 W/mK and increases the bird’s x by 2.769 x 10-3 m. Material “B” has a K of 0.17 W/mK and increases the bird’s x by 1.308 x 10-2 m. The bird’s internal temperature is 311.0 K (we are assuming that they are endothermic) and the temperature of the ground is 260.0 K. The distance from the exterior of the bird’s skin to...

1) Before an exam, a student has only studied 20 of the 28 topics corresponding to the subject of the exam. This is done by randomly extracting two subjects and leaving the student to choose one of the two to be examined. Find the probability that the student can choose one of the topics studied in the exam. 2) The compressive strength of a series of cement samples can be modeled with a normal distribution with an average of 6000...

3. (No computer output is accepted) A typical person in America has 155 friends in Facebook, 210 followers in Instagram and 155 followers in Twitter according to USA Tomorrow. A random sample of 30 people is selected and the following summary statistic are obtained. (Assume that the variables are normally distributed.) Sample Mean for Facebook is 120.7 Sample Mean for İnstagram is 210.3. Sample Mean for Twitter is 154.5 Sample Standard Deviation for Facebook is 5.2 Sample Standard Deviation for...

typical student has a normal distribution with mean of 10 minutes and standard deviation of 2 minutes to complete a question. The total exam has 80 minutes. how many questions should the exam have so that only 6 in 10,000 students failed the exam? (that is, p(y>80) = 0.0005)

A plane wall has thickness of 5 cm, thermal conductivity of 2 W/mK and generates heat. The left face of the wall (x=0) has a surface temp. of 80C and has air at 20C flowing past it with a heat transfer coefficient of 50 W/m^2K. If the right face is insulated then the temperature distribution through the wall has a general format T(x)=A+B*x+C*x^2 (a) Draw a properly labeled diagram (including a representative temperature distribution), state all assumptions and calculate the...
