The use of insulation in the walls of homes minimizes heat loss through which process? conduction convection radiation vaporization i have it narrowed down to the first two! someone just explain to me .

The force will determine the acceleration.

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

What’s #16 asking and how do i solve it?
