(1) create three files to submit: itemtopurchase. h - struct definition and related function declarations itemtopurchase. c - related function definitions main. c - main() function build the itemtopurchase struct with the following specifications: data members (3 pts) char itemname [ ] int itemprice int itemquantity related functions makeitemblank() (2 pts) has a pointer to an itemtopurchase parameter. sets item's name = "none", item's price = 0, item's quantity = 0 printitemcost() has an itemtopurchase parameter. ex. of printitemcost() output: bottled water 10 @ $1 = $10

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.
