Yes 5*7h is the same as 35h
In series combination, Current(I) remains same among all the resistors, but voltage(V) changes. So: V(Equivalent) = I(Equivalent) * R(Equivalent) R(Equivalent) = V(Equivalent)/ I(Equivalent) R(Equivalent) = IR1+ IR2+...+IRn / I R(Equivalent) = I(R1+R2+...+Rn)/ I R(Equivalent) = R1+R2+...+Rn
1/R = 1/60 + 1/60+ 1/60+ 1/60 + 1/60 1/R = 5 / 60 R = 60/5 R = 12 ohms.
5(r+5) is.
I?=I source(R equivalent / R?)

r2 + r - 20 = 0(r + 5)(r - 4) = 0r + 5 = 0 or r - 4 = 0r = -5 or r = 4

No, they are not.
Moment of inertia of hollowsphere = 2/5 M(R^5-r^5)/(R^3-r^3)
1 to 6 = 2 to 12
The Arabic equivalent to the letter "r" is Ra (ر).
factor out the common monomial, 5. 5(r^3-1) Factor as a difference of cubes. 5(r-1)(r^2+r+1)
