Write down two conditions required to make the resistivity and resistance of a conductor equal​

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

the answer is a)

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
