What kind of heat energy does the sun warm you with?

Explain vector addition, triangle method and parallelogram method

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
