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.
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 toassume that its composition and cross-section are constant along its length. Thiscould be a risky assumption, especially since the length was increased ... possiblyby stretching the wire, which would certainly affect the cross section.But without overthinking the situation and making myself nervous about it, lets justassume uniform composition and cross-section along the entire length, throughoutthe observation period. Then its resistance also increases by 1%.
5 m/s^2 (or 4.9 m/s^2 if you want to be exact) Since acceleration is zero when air resistance is equal to weight of object, and the most acceleration possible is 10 m/s^2 (or specifically, 9.8 m/s^2), then when air resistance is half of her weight, acceleration is also half, meaning 5m/s^2.
If the speed of the body is reduced to half, its kinetic energy would decrease by a factor of four. This is because kinetic energy is directly proportional to the square of the velocity of the object. So, reducing the speed by half results in the kinetic energy being reduced by a factor of four.

the power will be reduced to the haflf because P=V2/R so when the resistance doubles the power reduced to the half of itsoriginal value

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.

Half-length typically refers to a measurement that is half of a specified full length. In various contexts, such as in textiles or construction, it can denote a reduced size or scale, allowing for easier handling or fitting. In terms of design or planning, using half-length can help in visualizing proportions or in creating more compact forms. The exact meaning can vary depending on the specific field in which it is used.
The radius is also reduced by half
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.
It cannot be reduced.
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
