If half of its length is increased by 2%, then its entire length is increased by 1%.
In order to know how this affects the wire's resistance, we'd want to be able to
assume that its composition and cross-section are constant along its length. This
could be a risky assumption, especially since the length was increased ... possibly
by stretching the wire, which would certainly affect the cross section.
But without overthinking the situation and making myself nervous about it, lets just
assume uniform composition and cross-section along the entire length, throughout
the observation period. Then its resistance also increases by 1%.
The resistance of a wire is directly proportional to its length, so if the length is reduced by half, the resistance will also be reduced by half.
If the length of the conductor is halved, the resistance of the conductor also decreases by half. This is because resistance is directly proportional to the length of the conductor. Shortening the length leads to fewer collisions between electrons and reduces the overall resistance.
Cutting a conductor in half will not affect its conductance, as conductance depends on the material and its properties, not its length. Conductance is determined by the material's ability to allow the flow of electric current.
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
If the length of the conductor is doubled while keeping the applied potential difference constant, the drift velocity of electrons will decrease by half. This is because a longer conductor provides more resistance to the flow of electrons, leading to a decrease in the overall drift velocity.

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
4.5 = 450%
61.5/100
It is decreased by half. If you decrease the width by half and leave the length alone, you get the same result.
0.005 = 5/1000
Shorter: less resistance in proportion, so 1/2 length, half resistance, 1/3 length, 1/3 resisttance, etc. Thicker, less resistance in inverse-squared proportion, (it's the *area* that influences resistance), so 2 x diameter, 1/4 resistance, 3 x diamater, 1/9 resistance, etc. Try this: 1/2 length, 3 x diameter, gives 1/2 x 1/9 = 1/18 the resistance.
The answer to two and a half percent is easy. Simply find one percent,double it to get two percent and then half one percent to find the half. Put them together and you have two and a half percent.

It is a quarter of a percent
6 1/2 % = 6.5 % = 0.065
