Answer:
200 C
Explanation:
Let C1 and C2 be their charges. According to Coulomb's law
where k = 
is the constant, R = 0.4m is the distance between them, F = 120 N is their resulting charge force
Since their total charge is 200C:
or 
We can substitute the above equation
or 
So the larger charge is C = 200 C
Answer:
hypothesis: Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the height of the rocket launch in meters
Explanation:
According to Archimedes' Principle, an Object's density determines the depth it will get by displacing the liquid or gas molecules... More the density, more it's depth.
