Elements may have similar properties and we can use the periodic table to us determine what they are. these three elements are alike in many ways but they do not share all properties. what property do these elements not have in common? mg, k, and ca a) same phase at room temperature. b) good conductors of electricity. c) same number of valence electrons. d) they form cations (positive ions).

as technology advances, new experiments often expose problems in accepted theories. c

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
