The illumination of an object by a light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. If two light sources, one four times as strong as the other, are placed 18 m apart, how far away from the stronger light source should an object be placed on the line between the two sources so as to receive the least illumination?

plz help

A 0.590 kg wood block is firmly attached to a very light horizontal spring (k = 200 N/m) as shown in Fig. 6-40. It is noted that the block-spring system, when compressed 5.0 cm and released, stretches out 2.3 cm beyond the equilibrium position before stopping and turning back. What is the coefficient of kinetic friction between the block and the table?

Im doing a senior project. My central question is: What habitats are zoo animals required to live in, and what consequences can occur when living in a controlled habitat versus a natural one? I cant seem to find any good sites to help me with my information. Anyone know any good sites for zoo info? All i come up with is zoo sites, but not any that give me info on a zoo in general.
