If a cart of 4kg mass has a force of 8 newtons exerted on it what is it's acceleration

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

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 are similarities and differences of reflection, refraction, diffraction and absorption?
