At high elevations, the force of gravity becomes less.
No, because you need to change something, and measure how high it goes to see how changing one thing can affect the height. For example, if you are using air to launch the rocket, you could change how much air pressure you use, and measure the difference. "How does air pressure affect height?" is a scientific question. Remember if you do this, you must keep everything else the same, or it won't be a fair experiment.

Depends on the weight and streamlining of the rocket. i regularly get a B6 up to an estimated 1,500 feet.
If the nose is pointy, the rocket will go faster, but if the rocket's nose is flat, it will just travel slower in the lower atmosphere, the height a rocket attains depends on the efficiancy of its engines, the amount of propellant carried and the launch profile. However, for a subsonic rocket (which is what most hobby rockets are) then a curved on not a pointy one is much better. I would suggest looking it up on wikipedia.
Aluminum is a commonly used metal for rocket construction due to its lightweight, high strength-to-weight ratio, and ability to withstand high temperatures. It is also readily available and cost-effective for manufacturing rocket components.
Not necessarily. The height a water rocket reaches is determined by factors such as water volume, air pressure, and launch angle rather than just the rocket's size. Other variables like weight and aerodynamics also play a role in how high a water rocket can go.
I dont care and i dont know
Yes
A strong low wind will very much affect it's angle of flight. We try to wait for breaks in the wind to launch. Wind is bad for parachutes too, a rocket that went high can float a mile or two on it's parachute.
Titanium is a reactive metal with a high melting point that is used in the manufacture of rocket nose cones. Its combination of strength and low weight make it ideal for aerospace applications.
High humidity can cause the body to retain water, leading to temporary weight gain due to increased fluid retention. However, this weight gain is usually minimal and not a result of actual fat gain. It is important to monitor overall calorie intake and exercise habits for long-term weight management.
