A carbon nanopaeticle contains 7000 carbon atoms. According to the Einstein model of a solid, how many oscillators are in this block
A space vehicle is coasting at a constant velocity of 28.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.523 m/s2 in the +x direction.
