Write a function sumsteps2 that calculates and returns the sum of 1 to n in steps of 2, where n is an argument passed to the function. For example, if 11 is passed, it will return 1 + 3+5+7+9+11. Do this using a for loop. Calling the function will look like this: >> sumsteps2(11) ans 36 For example: Test assert (sumsteps2 (11) = 36) assert (sumsteps2 (23) 144) assert ( sumsteps2(57) = 841) assert(sumsteps2(3)4) assert (sumsteps2(1001) 251001)

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.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
