Albert Einstein is quoted as saying, “Not only to know how nature is and how her transactions are carried through, but also to reach as far as possible the utopian and seemingly arrogant aim of knowing why nature is thus and not otherwise.” What do you think Einstein meant by this?

) A 1 gallon bottle of a certain brand of bleach costs $1.49. Determine the cost to buy enough bleach to supply 100.0 grams of active ingredient (NaOCl), assuming 6.25% active ingredient by mass and a density of 1.05 g/ml.

A large freshwater (total mass of water 10^5 kg) lake contains no lithium. A sudden spill releases a constant lithium contaminated flow discharging 3.98*10^8 mg of lithium/hr. How long will it take until the lake reaches a lithium concentration of 1.1nmol/kg?

Consider the two spheres shown here, one made of silver and the other of aluminum. The spheres are dropped from a height of 1.7 m. Composition - aluminum Density= 2.70 g/cm³ Volume 196 cm³ Composition - silver Density 10.49 g/cm³ Volume=196 cm³ What is the kinetic energy of the silver sphere at the moment it hits the ground? (Assume that energy is conserved during the fall and that 100%% of the sphere's initial potential energy is converted to kinetic energy the time impact occurs.) Express your answer to two significant figures and include the appropriate units. Ek = Value Units
