Perform in matlab and show code

use matlab and planck’s law to make a plot of the blackbody radiation curve (radiant spectral flux density as a function of wavelength) for a human ( assume your skin temperature is 30 degrees c, and make your plot for the wavelength range 0-50 µm.

Which of the following is an example of units for speed

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
