Assume that a procedure yields a binomial distribution with a trial repeated $n = 8$ times. Use either the binomial probability formula (or technology) to find the probability of $k = 2$ successes given the probability $p = 0.42$ of success on a single trial. (Report answer accurate to 4 decimal places.) $P(X = k) = \text{_____}$

(a) A shunt dc motor has a rated armature current of 20 A , rated (10 marks) field current of 0.5 A , rated voltage of 25 V and maximum rotational speed of 750 rpm . When the rotor is locked, an armature voltage of 1.02 V produces 17 A of current flowing in the armature; while a field voltage of 25 V produces a field current flow of 0.5 A . At no load, with the terminal voltage applied is 24 V , the motor speed is 750 rpm and the current drawn by the motor is 1.32 A . The brush voltage drop is estimated to be 2 V in all conditions. The stray loss is estimated to be \( 1 \% \) of the input power. Determine the output power produced by this motor and the efficiency at the rated conditions.

Para un flujo hidrĂ¡ulicamente liso, con un tirante $h$, demuestre que el promedio de velocidades evaluadas a $0.20h$ y $0.80h$ corresponde a la velocidad a $0.40h$. Considere $u^*$ y $v$ como constantes. $\frac{u(0.40h)}{u_*} = \frac{\frac{u(0.20h)}{u_*} + \frac{u(0.80h)}{u_*}}{2}$ $u(0.40h) = \frac{u(0.20h) + u(0.80h)}{2}$
