I need some help with "C" if possible

(a).

Power1 = V2 x clock rate x C.Power2 = 0.9 Power1

=> C2/C1 = 0.9 x 52 x 0.5 x 109/3.32 x 1 x 109 = 1.03

(b).

Power2/Power1 = V22 x clock rate2/V12 x clock rate1

Power2/Power1 = 0.87 => Reduction of 13%

Suppose we have developed new versions of a processor with the following characteristics. Version Voltage Clock Rate i. Version 1 1.75 V 1.5 GHz Version 2 1.2 V 2 GHz i. Version 1 1.1 V 3 GHz Version 2 0.8 V 4 GHZ (a) [5 points) How much has the capacitive load varied between versions if the dynamic power has been reduced by 10%. (b) [5 points) How much has the dynamic power been reduced if the capacitive load does not change? (c) [10 points] Assuming that the capacitive load of version 2 is 80% the capacitive load of version 1, find the voltage for version 2 if the dynamic power of version 2 is reduced by 40% from version 1
