Assume a program contains a void function named the function receives two double variables named oldprice and newprice. the function multiplies the contents of the oldprice variable by 1.1, then stores the result in the newprice variable. which of the following can be used to call the calcnewprice() function? (a) calcnewprice(double oldprice, double newprice); (b) calcnewprice(& oldprice, newprice); (c) calcnewprice(oldprice, & newprice); (d) calcnewprice(oldprice, newprice);

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.
