We used a 1d model of the earth in class to model climate change. rewrite the matlab code for the equilibrium temperature of the earth. assuming no greenhouse gas effects, what is the equilibrium temperature the earth would have if the following were the various constants in the model: sigma = 5.67e-8; epsilon = 0.612; alpha = 0.30; s = 1365; what is the equilibrium temperature in degrees celsius -- report only the number and not the units.

On a average work day more than work place firs are reorted

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
