A ""doomsday"" asteroid with a mass of 1.0 * 1010 kg is hurtling through space. Unless the asteroid’s speed is changed by about 0.20 cms, it will collide with Earth and cause tremendous damage. Researchers suggest that a small ""space tug"" sent to the asteroid’s surface could exert a gentle constant force of 2.5 N. For how long must this force act?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
