Best ResponseYou've already chosen the best response.1its the rate at which the bacteria is travelling 20 newton metres, and the μ is the symbol for mu,,,,,i'm not really familiar with these units

Best ResponseYou've already chosen the best response.2\[V= \frac{ 20 * 10^ {9}}{ 10^{6} }=20*10^{3} m/s\] and length = 0.001 m now firstly, find the acceleration using the relation \[U^2=2*a*D\] where D is distance \[a=\frac{ U^2 }{ 2D }=(20*10^{3})/2*10^{3}=10 m/s^2\] now force F=mass * acceleration\[F= 10^{8}* 10= 10^{7} N\] = 10^(7) N hope this helps you and remember every power is negative :D
