can any one answer these quistions : :uhh:

i am in big problem if no one answer :yuck:

Question :

1- if the relation between the resistance and the temperature is given by Rt=R0 ( 1- α t1/3) where the resistance at 00C is 60 Ω and the temperature coefficient is 0.1 0C-1/3.

a- Name the independent and dependent variables.

b- Draw the R-T graph by assuming different values of "t" ranged between 0 and 64 0C .

c- Find the value of the resistance at t=270C

d- Explain if this material is conductor or semi-conductor and why?

2- if the relation between the resistance and the temperature is giving by Rt=R0 ( 1-+α t) where the resistance at 0 0C is 20 Ω and the temperature coefficient is 0.050C-1

a- name the dependent and independent variables.

b- Draw the R-T graph

c- Find the value of the resistance at t=25 0C

d- Explain if this material is conductor or semi-conductor and why?
