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 notation

Explanation / 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
