15 J of work were expended moving an 18 kg block. At what velocity did the block move? a.)1.3 m/s b.)1.1 m/s c.).9 m/s d.).7 m/s

a.)1.3 m/s *To solve for velocity, you should use the formula W = KE, where Work = W, and Kinetic Energy = KE. This is because any work that is done to accelerate an object is converted to the kinetic energy of that object (the work-energy theorem). So, W = (1/2) mv2. Plugging in the block's weight (18 kg) and the work done (15 J) will give you a velocity of 1.3 m/s.

How does iron form rust?

When water (or an even better electrolyte) turns iron and oxygen into iron oxide (Fe2O3); this is a chemical process. Helium and neon are both inert noble gases, so they do not react chemically. When sugar dissolves in water, the sugar particles become evenly distributed throughout the water, forming a solution. However, neither is changed chemically. The sugar can be restored by boiling off the water. Ice melting does not alter the chemistry of H20.
