A beaker is filled with a oil with a density of 930 kg/m^3. Attached to the bottom of the beaker is a spring oriented vertically. A 5.0-kg block of wood is attached to the end of the spring, causing the spring to stretch. Wood has a density of 750 kg/m^3. What is the buoyant force on the wood block?

a. 26. 6N
b. 1190N
c. 48.1N
d. 60.8N
e. 18.7N
f. 97.0N

When a neutrally charged atom loses an electron to another atom, the result is the creation of a. two charged atoms. b. two negatively charged atoms. c. two positively charged atoms. d. two neutrally charged atoms.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
