According to newton's law of cooling, the temperature u(t) of an object satisfies the differential equation du dt = −k(u − t), where t is the constant ambient temperature and k is a positive constant. suppose that the initial temperature of the object is u(0) = u0. (a) find the temperature of the object at any time

True or false graphs must include scales that increase by the same amount

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
