In which situation will the lowest resistance occur?

There may be two types of resistances here:

Air resistance: for example when something is falling down, the air will push the object upwards. As a bigger surface has the object, more air is pushing, so if you want to reduce the resistance yo must reduce the surface area. For example, a sheet of paper will experience more resistance if it is open if you make a small ball with it.

Electric resistance: This is the resistance of conductors against the electrons that try to travel along with it.

there are two equations here.

R = p*L/A, this talks about the volume and density of the conductor, where p is the density, L is the length and A is the area perpendicular to the direction in which the electricity flows.

Then if you reduce the length, and increase the area, the resistance will be reduced.

the other equation is: R(T) = R0( 1 + a*(T - 20°))

Where R0 is the resistance at 20° and a is a coefficient for T = 20°.

Here, you can see that at smaller temperatures, the resistance decreases, so we can conclude that we must increase the area, and decrease the length and temperature.

0.11 m/s and 0.28 m/s should be correct

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
