If you double the lenght of a wire, how does the resistance of the wire change? and

If you make a wire twice as thick, how does the resistance of the wire change?

If the length of a wire is doubled the resistance is shortened if it is thicker is is more durable due to the electrons having more room to spread out and flow through the wire

I hope this will help you

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
