A student thinks that scientific theories are not reliable sources of information, since scientists tend to argue about the details of them. What is the flaw in the student's reasoning? A* The arguments between scientists tend to make theories stronger, not weaker.
B* Scientists rarely disagree about scientific theories.
C* Scientific theories do not change over time, which makes them reliable.
D* It is rare for a scientific theory to be valid for more than a few years.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
