some say that total entropy of the universe would start to decrease rather then increase causing time to move backwards rather then forward

i was wondering what causes the Earth's tilt on its axis. i was thinking that it might be from einsteins theory of gravity, in which a large object, such as the sun, causes a bend in space time forming gravity and causing Earth to rotate around it. any info would be great, thanks

does anyone know at what temperature salt stops working and the area would remain icy?

thanks guys, the other thing in static equilibrium would be net torque would equal zero but i didnt think there was any torque in this sytem, thanks again for your help

the problem reads: a uniform bridge 20 m long and weighing 400,000 N is supported by two pillars located 3 m from each end. if a 19,600 N car is parked 8 m from one end of the bridge, hoe much force does each pilliar exert? i was thinking about using something like (W1)(d1) = (W2)(d2) that...

question: on a sunny day at the beach, the reason the sand gets hot and the water stays relatively cool is attributed to the fdiffernce in which property between water and sand? is it specific heat or thermal conduvtivitiy?? our class and our teacher argued over this all class, thanks for...
