Amagnetic field is aligned perpendicular to the plane of a circular loop of wire with radius 5.0 cm and 20 turns. the magnetic field b changes with time t according to the following function: b 12 exp(-3t) +1.5t +6 t determine the induced emf in the circular loop of wire as a (i) function of time, and the time at which the induced emf is 0.1 v. (ii) if the magnetic fieldis instead aligned at 30° with respect to the normal of the circular loop of wire, find the induced emf as a function of time.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.

Which statements identify what astronomers currently know and think will happen with our universe? check all that apply. the big bang produced dark energy, which accounts for some of the energy needed to expand the universe. the vastness of space may contain a type of matter known as "dark matter." the universe is currently shrinking at a rapid rate. the universe is currently expanding at an accelerating rate. the big bang theory explains all the energy and matter discovered by scientists.
