Answer:
The resistance approaches infinity
Step-by-step explanation:
We are given
The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation
where
p represents the resistivity of the wire’s material
L represents the length of the wire
d represents the diameter of the wire
now,
d approaches to 0
so, we can plug d=0 and find R
So,
The resistance approaches infinity
Answer 0.6
(3/2)x(2/5)= (3/5) or 0.6
The volume of a cube with side length equal to x, is
,
thus, the volume of a cube shaped box, whose side length is (5a+4b) is :
,
The volume is already expressed in terms of a and b, but we can expand the expression
, as follows:
Answer:
,
