The surface area is quadrupled.
if length and width are doubled then the volume should mulitiply by 8
It quadruples.
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
the surface area quadruples.
The area also doubles.
if length and width are doubled then the volume should mulitiply by 8
It quadruples.
Assuming no change in the width, yes.
Area = length*width new Area = 2 * length * width Area is doubled
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
The change in the surface area depends on the shape. The volume will double.
The surface area of the 'wall' doubles, but the base areas remain the same.
The Area of a square can be written as it's side length^2, orA = s^2if the side length is doubled, then s' is 2s.A' = (s')^2A' = (2s)^2A' = 4s^2 = 4*AWhen the side length is doubled, the area increases by a factor of 4
Surface Area becomes 4 times the original when its edges are doubled because Suraface area = (edge)^2
this is incorrect -- quick example.. 2"x2"x2" cube -- will have a surface area on each side of 4"sq (2x2=4) --- now make that 4"x4"x4" -- this cube will have a surface area on each side of 16"sq (4x4=16)
the surface area quadruples.
If the length of a material is doubled, the resistivity remains the same. Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. However, the resistance of the material will double if the length is doubled, according to the formula R = ρ * (L/A), where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
