The mass of a certain neutron star is 1.2 × 1031 kg (6 solar masses) and its radius is 5000 m. what is the acceleration of gravity at the surface of this condensed, burned-out star

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.
