Iam trying to the max voltage produced from a magnetic being dropped through a wire with a relationship on the height the magnet is dropped from. i know that emf=-v= n(partial derivative of magnetic flux). but i am not sure how to relate this to the height the magnet is dropped through a solenoid (wire coil). it would be amazing if anyone could me with this formula. i tried finding the velocity with ki, ko and ui, and uo, but i don't know how to join them. i am dropping a magnet through a wire from varing heights and measureing the max voltage that is measured. i am trying to derive the ideal equation for this procress

the independent variable, or the one that is intentionally manipulated is the speed.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
