The answer is A. Plant growth, Plant growth is the only thing that can actually be tested and scientificly measured, hope this helps!!!!
The answer would be true so you would know which way it was going and how fast it was moving towards you
Answer:
the molecules form new chemical bonds
Explanation:
Answer:

Explanation:
Given:
mass of the wire, 
length of the wire, 
current in the wire, 
Now form the Lorentz force we know that every current carrying wire experiences a magnetic force on it due to the magnetic field components perpendicular to it.
Mathematically given as:


here: we nee to balance the gravitational force on the mass.
magnetic field


This magnetic field must be perpendicular to the direction of current in the wire and the these two directional quantities must lie in a plane normal to the direction of gravity according to the Fleming's left hand rule.
