Well, to be broken down, resistance is the opposition that a substance offers to the flow of an electric current.
What would happen to a light bulb if the voltage increased, but the resistance stayed the same would be this:
The current, being directly proportional to the voltage, would increase, causing the light bulb to increase I'm brilliance, which means: it would simply become brighter.
Hope I helped you out!
Explanation:
Given that,
Size of object, h = 0.066 m
Object distance from the lens, u = 0.210 m (negative)
Focal length of the converging lens, f = 0.14 m
If v is the image distance from the lens, we can find it using lens formula as follows :
(a) Magnification,
(b) Magnification, 
h' is image height
Hence, this is the required solution.
The difference in the force exerted by the ground during a race between these two species is 259.25
<h3>What is force?</h3>
Forces are influences that can change the movement of an object. A force can change the velocity of an object with mass, i.e. accelerate it. Forces can also be described intuitively by pushing or pulling. A force has both magnitude and direction and is a vector quantity.
Force exerted by the lion:
Normal force = mg
170 = m × 9.8
m = 17.34 kg
Forward force = ma
= 17.34 × 10.0
= 173.4 N
Total force = Normal force + Forward force
Total force = 170 + 173.4
= 343.4 N
Force exerted by the man:
Normal force = mg
75 = m × 9.8
m = 7.65 kg
Forward force = ma
= 7.65 × 10.0
= 76.5 N
Total force = Normal force + Forward force
Total force = 7.65 + 76.5
= 84.15 N
The difference in the forces exerted by these species is:
343.4 N - 76.5 N = 259.25 N

The answer is C (They are inversely proportional). I have had this question before and C is the correct answer.
-- Photographic film detects radiation.
-- Gas occupies the whole container.
-- The Geiger counter is used to detect and measure
the intensity of radiation.
-- An atom is the <span>smallest particle to retain characteristics
of the element.
-- The atomic mass is the mass of the protons and neutrons in the atom.</span>
(The electrons hardly make any difference. One proton or neutron has
as much mass as more than 1800 electrons.)
-- A solid has a fixed shape.
-- The neutron is electrically neutral. It has no charge.
-- The proton has a positive charge.
-- The electron has a negative charge.
-- The atomic number is the number of protons in the nucleus of an atom.
