4. ### Physics Universal Gravitation?

F = GMm/ r ^2 = mg/25  -- > r = sqrt(25*GM/g) Now note that g = GM/ R ^2   where R = radius of earth so r = 5*sqrt(GM/(GM/ R ^2)) = 5R = 5*6367 km = 31890 km

6. ### There are n equal resistors. Series connection of these resistors gives 98 Ohms. Parallel connection of these resistors gives 2 Ohms. ?

R *n = 98 R /n = 2  R = 2n 2n*n = 98 n = √ 98/2 = 7  R = 14 ohm  check :  14*7 = 70+28 = 98 ohm 14/7 = 2 ohm

7. ### Suppose NASA has plans to create a permanent space station in low orbit above Mars. ?

mass M = 6.42*10^23 kg  radius r = 3.40*10^6 m  Vo^2*(3.40+0.12)*10^6 = 6.42*10^23*6.67*10^-11  Vo = √ 6.42*10^23*6.67*10^-11 / ((3.40+0.12)*10^6) = 3490 m/sec
