If 50 identical light bulbs are connected in series across
a single power source, then the voltage across each bulb
is ( 1/50 ) of the voltage delivered by the power source.
A control variable is the one element that is not changed throughout an experiment.A dependent variable is a variable whose variation does not depend on that of another.A independent variable is a variable whose value depends on that of another.

46.58m/s²
26.43kg
Explanation:
Given parameters:
Force = 67N force = 185N
Mass = 1.43kg acceleration = 7m/s²
Unknown:
Acceleration = ?
mass of the object = ?
Solution:
According to newton's second law of motion "the net force on a body is a product of its mass and acceleration".
Force = mass x acceleration;
For the first problem;
the unknown is the acceleration;
Acceleration = = = 46.58m/s²
Using the same law, to find the mass of the second object, we make it the subject of the formula;
mass =
mass = = 26.43kg

Answer:
Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter.
