Cline quiz remote Here was an example used today when talking about tension and acceleration, what is point of repeating the book, youtube videos when the youtube videos are produced by other professors on open stax chapter by chapter before the lockdown with higher quality because they have a video production crew Math 5x+2y-6=0 2x+8y-12=0 Draw two lines and the intersection point is the solution with 2 significant figures. Solving exactly gives many significant figures. Why uses a graph Physics When the numeric coefficients shift in a problem due to changes in numeric information (in real life applications), the intersection point on the graph will drift/shift which is more difficult to perceive using the algebra method. Prospection No one out-remember Google, so prediction on how an answer will drift/shift is physics, recital of a problem with exact number coefficients has zero value in physics. Besides, next generation artificial intelligence, machine learning, statistical learning, are graphical predictions, Open stax university physics page 317 45. A 2.00 kg block (mass 1) and a 4.00 kg block (mass 2) are connected by a light string as shown; the inclination of the ramp is 40.0 . Friction is negligible. What is (a) the acceleration of each block and (b) the tension in the string? 1 2 40 Quiz-a Show a graphical solution. Describe how the tension and acceleration values would change when the hanger mass would increase by 10 percent, 4.4 kilogram. Plot tension on y-axis, acceleration on x-axis for the 2 kg using the 2 kg equation of (T, a). Repeat for the 4 kg using the 4 kg equation of (T, a) on the same graph, the intersection is the graphical solution. Repeat
