Air flows over a l-meter-wide flat plate at a constant velocity of 20 m/s and ambient conditions of 20 kPa and 20 °C. The whole plate is heated to a constant temperature of 134 °C. (a) What is the total heat transfer from the first 50 cm of the plate? (b) What is the total heat transfer between 50 cm and 100 cm from the leading edge?

Physics 121 Spring 2021 - Document #11: Homework #04 & Reading Assignment page 4 of 8 Problem 1: Gnome Ride - This from a Previous Exam I. A Gnome of given mass M goes on the Gnome Ride as follows: He stands on a horizontal platform that is connected to a large piston so that the platform is driven vertically with a position as a function of time according to the following equation: y(t) = C cos(wt) Here w is a constant given angular frequency, C is a given constant (with appropriate physical units) and y represents the vertical position, positive upward as indicated. Part (a) - What is the velocity of the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Part (b) – What is the net force on the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Part (c) – What is the Normal Force on the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Some Possibly Useful…

Newton’s 2nd Law Lab (Modeling­ friendly lab)   Go to the PhET simulation Forces & Motion. https://phet.colorado.edu/sims/html/forces­and­motion­basics/latest/forces­and­motion­basics_en.html Select “Acceleration” Click to show Forces, Sum of Forces, Values, Mass, and Acceleration. There are two experiments for this activity – make sure you include both.   Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero.  This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Applied Force information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best –…

HEAT TRANSFER CASE:  I want to know what temperature in (°F) the cylinder will have inside. It's a heat transfer problem. what is T2 ? HEAT TRANSFER They gave me an answer all squashed together that i can't make sense of it. If you could help me makes sense of it thank you!
