Daniel has a sample of pure copper its massive is 89.6 grams(g) and its volume is 10 cubic centimeters (cm3) what's the density of the sample

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

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
