James took two pea plants, placing one in a dark closet and the other on a sunny window sill. both are located in air-conditioned rooms. he then measured the growth of the pea plants after a week. which of the following best describes the purpose of this experiment? question 5 options: to determine the effect of lack of water on plant growth to determine the effect of air conditioning on plant growth to determine the effect of sunlight on plant growth to determine the effect of enclosed spaces on plant growth

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
