To be a bit more helpful, the masses are proportional to the radius squared times the length, and the resistances are proportional to the length divided by the radius squared - so just set it up as proportionality, cancel out what you can, and what is left is your answer. Resistance doesn't depend upon mass ..
Besides, what is the relation between resistance and length?
The relationship between resistance and wire length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional .
Also, is resistance directly proportional to area? The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor.
In respect to this, does resistance depend on mass?
The specific resistance or resistivity of a wire is the property of the material of it. It does not depend on mass, length or cross-section of wire. It may change with temperature.
What is the unit of resistance?
The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm.

What is the formula of resistance?
How do I calculate resistance? The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A): Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that if you increase the voltage, the current will also increase.What causes resistance?
Resistance - Higher tier. An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.How do I calculate resistance?

Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.Is resistance directly proportional to length?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature.How is current measured?
The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter. These conduction electrons are the charge carriers in metal conductors.What happens to resistance if length is doubled?
Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire. Doubling the length will double the resistance, but the wire also must get thinner as it is stretched, because it will contain the same amount of metal in twice the length.Does air resistance increase with mass?
The deceleration due to air resistance will depend on the object mass: a=Avn/m, so air resistance slows a heavy object less than it slows a light object. At a given velocity the force due to air resistance is the same for both ballons because it only depends on the shape and speed.Does resistivity affect resistance?
Resistivity Summary The resistance of a conductor is directly proportional to its length (L) as R ∝ L. Thus doubling its length will double its resistance, while halving its length would halve its resistance. Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A.What factors affect air resistance?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.Does mass affect drag?
The drag on a solid, rigid object isn't affected by the object's mass. However, drag is just the portion of the force on the object that's due to the fluid. The net force on the object will of course be affected by the object's mass, assuming that gravity is one of the forces on the object.Do heavier objects have less air resistance?
Heavier objects do not fall faster than lighter objects when they are dropped from a certain height IF there is no resistance from the air. Because of this, the resistance from the air slows the fall of the lighter thing. But if both objects had the same ratio of mass to surface area, they would fall at the same rate.How does mass affect air resistance of a falling object?
Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. The horizontal force applied does not affect the downward motion of the bullets -- only gravity and friction (air resistance), which is the same for both bullets. Air resistance makes a feather fall slower.Does mass affect acceleration?
"What are the factors that affect the acceleration due to gravity?" Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.What happens when there is no air resistance?
When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum. A rock and a feather are released from rest from the same height with air resistance on.Who discovered Airset?

What is the property of resistance?
Resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors.What is meant voltage?
Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field. An example of direct voltage is the potential difference between the terminals of an electrochemical cell.What is Ohm's law in electricity?
Ohm's Law and Resistance. Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.
