False
Step by step explanation
The resistance of a conductive wire is given by:

where

is the material resistivity

is the wire length

is the cross-sectional area of the wire
The length of the wire is quadrupled, so if we call L the original length and L' the new length, we can write

Similarly, the radius of the wire is doubled (r'=2r), so the new area is

And if we substitute into the equation, we find that the new resistance of the wire is

Therefore, R=R': this means that the resistance of the wire did not change.
Answer:
999 V
Explanation:
Charge deposited on the capacitor
= current x time
= 2 x 10⁻³ A x 5 x 10⁻³
= 10⁻⁵ C
increase in volt = charge deposited / capacitance
10⁻⁵ / .1 x 10⁻⁶
= 10² V
= 100 V
voltage in the beginning = -1 V
voltage at the end
= -1 + 100
99 V .
