So the more the thrust would give me a greater height ? The faster the water comes out would give a greater height ? than that of something a little more constant? i think that a fraction of a difference in the radius could make a difference? that's me assuming yet i know they say don't...

Alright what i am trying to do is to find the proper ratio of water in a water bottle. The Bottles are 591 ml and 2 L I am trying to figure out the equation to get the maximum height of the rocket. Does anyone know how i can get this equation ? i haven't factored the...

The whole idea of me posting this is to get help ... ?

You are using a transformer with 800 loops in the primary and 80 loops in the secondary . if the transformer is plugged into a 120 v outlet and protected by 15 a cb what is the maximum power rating of an application that could be used ?

f=ma, a = m/f , a = 9.1x10^-31 / 1.2x10^-12 = 7.6 x 10 - 19 the answer according to the back of the textbook is way different a = 1.32x10^18m/s^2 maybe the answer is wrong? in the book

i know this but how do i get the acceleration when i don't have the mass of the electron?

An electron has a velocity of 5 x 10^6 m / s perpendicular to a magnetic field of 1.5 T. What force and acceleration does the elcetron experience? ok i get the Force part by using F=qvB, how do i get the Acceleration? F= 1.2x10^-12 N A= ?
