"water moves in a pipe from the ground up to a height" of 11 m. at the bottom of the pipe the water has a velocity of 1 m/s. as the pipe goes up it reduces in diameter and at the top of the pipe it has a velocity of 12 m/s and a pressure of 207000 pa. find the necessary pressure at the bottom of the pipe to deiver the water to the top.

Would corn syrup, molasses, or pancake syrup make a good lubricant in a car engine? explain your answer.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?
