Hi everyone, I would gladly appreciate if you could please help me with my physic homework. Please insert the image if option there but if not there please tell me what to draw. The question is: 17. A machine is often designed when the work required to move an object needs a force larger than the person can exert. Your task is to lift a 400-kg boulder from the ground and place it on a platform 3.0 m high.

a) Make a sketch of a machine (or a combination of machines) that use a force provided by one person to accomplish this task.

b) Label the input and output force(s) on your sketch.

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?

What does si stand for,when referring to a system of measurement

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”.
