Part 1. if an object oscillates 100 time in 50 seconds what will be the frequency and periodic time?

part 2. consider a mass oscillating with simple harmonic motion represented by the equation x=2/5cos[2π t + π ] meters . calculate the amplitude, displacement, speed and acceleration if it completes the motion at a time of 0.7 seconds

b.a device that inputs heat into a cool object

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
