A manometer with a sealed end is used to measure air pressure, water is the manometer fluid. The air in this situation has a specific gravity of 0.001292 at ambient temperature and pressure. If fluid 1 (the air) generates a 6.7 inch height difference from the top of the manometer, fluid 2 (the sealed end) generates a 50. mm height difference from the top of the sealed end of the manometer, and pressure at the top of the tube is ambient (1.0 atm), what is the density of the second fluid

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.

If you let go of the notebook after lifting it, will it move? how?
