While in Canada, the engineer buys a new electric toothbrush. When she returns home she designs anothertransformer so she can use the toothbrush in India. This transformer also has an input coil with 240 turns.
How many turns should the output coil have?

-- 'Ca' (Calcium) is an element.
-- The proton has a positive charge.
-- Nuclear fusion results in the synthesis of atoms of new elements.
-- H₂O (water) is a chemical compound.
-- Nuclear fission is a decay of the nucleus.
-- The atomic number of an element is the number of protons
in each atom of it.

if the vector sum of the force applied by you and the force applied by another person is zero, then the object will not accelerate since the net force on the object is zero in this case. hence the object will not move at all or if it was already moving , will move at constant velocity.
if the vector sum of the force applied by you and the force applied by another person is non-zero, then the object will not accelerate since there is net force on the object in this case. hence the object will accelerate.
B) Electrons are added to two negatively charged objects.
C) Two oppositely charged objects are moved farther apart.
D) The charge on two positively charged objects is reduced.
Answers
By definition we have that the electric force is given by:
Where,
k: proportionality constant
q1: electric charge of object 1
q2: electric charge of object 2
d: distance between both objects
Therefore, to increase the electric power there are two possible cases:
1) Add more load to each object
2) Decrease the distance between objects.
The option that increases the electric force for this case is:
Electrons are added to two negatively charged objects.
This is because the values of q1 and q2 increase.
Answer:
A change that increases the electric force between objects is:
B) Electrons are added to two negatively charged objects.

voltage applied to
a circuit and the
current in a circuit?
Answers
Answer:
The relationship between voltage and current is called resistance. The relationship between all 3 is called Ohm's Law.
General Formulas and Concepts:
Circuits
Ohm's Law: V = IR
- V is voltage/EMF
- I is current
- R is resistance
Explanation:
Ohm's Law is the fundamental basic for an ohmic surface. All circuits follow Ohm's Law if it is ohmic and assuming all other things constant. It tells the importance of the relationship between voltage, current, and resistance in a given current of a battery, wire, and resistor.
It is wise that you memorize this and understand the relationship between all 3.
