an object has a moment of inertia of 28.24 kg m^2 and spins with an angular velocity of 3.25 1/s, then its moment of inertia changes to 13.46 kg m^2. If angular momentum is conserved what must the new angular velocity be?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Asystematic approach to problem solving is called a (an)
