A graduated cylinder has 35.0 mL of water in it before an object is dropped inside. The new volume is 38.5 mL. What is the volume of the object in cm3?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

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

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and
