Question
i need someone to slove all of it
In an experiment in heat conduction the following formula is used: All the quantities are kept constant except d and delta t. If you wanted to plot a straight line graph, what would you plot on the x-axis and what would you plot on the x-axis? What will be the constant of proportionality? A man walks from a point A to a point B, a distance of 0.800 m at 4.50 m/s and back to the starting point at 2.00 m/s in a straight line. What is the average speed over the entire trip? What is the average velocity for the whole trip? Two points A and B located at the following locations given polar coordinates A at (5.22 m, pi/4) and B at (2.62 m, pi/6). Find the straight line distance between A and B Vector A = 3.00 m at 30 degrees and vector B = 6.00m at 60 degrees, draw neat sketches to show the following. A + B A - B A - 2B Find A + B in i - j notationExplanation / Answer
on x axis plot d^2
on y axis plot 1/(delta_t)
constant of proportionality = Q*4L/(pi*(Tn-Tc)
==============
#2)
average speed = total distance /total time
Vavg = (0.8+0.8)/(0.8/4.5 + 0.8/2)
Vavg = 2.77 m/s
(ii)
average velocity = total displacement/total time = 0
#4)
Ax = 5.22*cos(pi/4) = 3.69 Ay = 5.22*sin(pi/4) = 3.69
Bx = 2.62*cos(pi/6) = 2.27 By = 2.62*sin(pi/6) = 1.31
distance = sqrt((Bx-Ax)^2+(By-Ay)^2) = sqrt((2.27-3.69)^2+(1.31-3.69)^2) = 2.77
