WebHence,the net work done for any displacement is zero. Similarly, in the reaction ,no work is done by the reaction as they act in the opposite directions on each link and thus cancel out. More answers below While moving an object up with force (mg), the total work done becomes 0 because the work done by gravity = negative of the work done by force. WebA spherically pulsating spherical star (non-zero monopole moment or mass, but zero quadrupole moment) will not radiate, in agreement with Birkhoff's theorem. More technically, the second time derivative of the quadrupole moment (or the l -th time derivative of the l -th multipole moment ) of an isolated system's stress–energy tensor must be non-zero in … maxpedition tc2 https://karenneicy.com
