Achild is on a pogo stick. at the top of her jump, her kinetic energy (ke) = 0 j, her gravitational potential energy (gpe) = 100 j, and the potential energy in the spring (spe) = 0 j. at the bottom of the jump, immediately before the child jumps again, what do ke, gpe, and spe equal? (assume a closed system.
a) ke = 0 j, gpe = 100 j, and spe = 0 j
b) ke = 50 j, gpe = 0 j, and spe = 50 j
c) ke = 100 j, gpe = 0 j, and spe = 0 j
d) ke = 0 j, gpe = 0 j, and spe = 100 j

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next

There is one girl i like and i don't know how to tell her that, i have a feeling she knows but if she doesn't i don't want to make a fool out of myself how is one way to boost my confidence on asking her out
