PHSC 1001 : Physical Science Test 1 Notes From Book
Document Summary
The asteroid was made of rock, not dynamite. Gasoline costs about 3. 50 a gallon: when you put that into energy to the wheels, that works out to be about 40 cents per kwh, however, standard lead-acid car batteries have to be replaces after about 700 charges. When you include battery expense, the cost per kwh is about 20 cents. It beats the cost of gas by a factor of 2: but because batteries take up so much space, it"s not an attractive option to many people. ; with this limited use, the batteries last much longer. Gasoline vs. tnt: in a lot of movies when a care crashes, it explodes. As it nears the ground, a small charge of high explosive explodes in the center, destroying the container and dispersing the fuel and mixing it with the air, but not igniting it. Isn"t it already being conserved: yes it is, but not all forms of energy have equal economic value.
