The particle moves from the origin to the point with coordinates (aa, bb) by moving first along the xx-axis to (aa, 0), then parallel to the yy-axis. How much work does the force do

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

What does the law of conservation of mass state?
