Answer to Question #129284 in Physics for RUBHASRI MUGAMBIKA A/P SANGAR

Question

1.4263mV to kV
2. 2.95km² to mm²

Answer 1

1. First, let's convert 4263mV to volts ($1mV = 10^{-3}V$ ):

$$4263\space mV = 4263\times 10^{-3}V$$

Then convert to kV ($1V = 10^{-3}kV$ ):

$$4263\times 10^{-3}V =4263\times 10^{-6}kV = 4.236\times 10^{-3}kV$$

2. First, let's convert 2.95km² to m^2 ($1km = 10^{6}m^2$ ):

$$2.95km² = 2.95\times 10^{6}m^2$$

Then convert to mm^2 ($1m^2 = 10^{6}mm^2$ ):

$$2.95\times 10^{6}m^2 =2.95\times 10^{6}\times10^6 mm^2 = 2.95\times 10^{12}mm^2$$

Answer. 1. $4.236\times 10^{-3}kV$, 2. $2.95\times 10^{12}mm^2$.
