Write a function in JAVASCRIPT that accepts an array as argument. The function should loop through the array elements and accumulate the sum of ASCII value of each character in element and return the total. For example: function([‘A’, ‘bc’, 12]); // returns 361 which is the sum of 65 + 98 + 99 + 49 + 50
Use of any built in string functions or built in array functions is not allowed,
Any help would be much appreciated

A motor with an internal resistance of R(motor) = 50 Ohms
requires a potential difference of V(motor)=20V to work properly.
As you don't have a 20V power source, you place two 12V batteries
in series with a custom-built resistor with resistance R1.
(a) How much current moves through the motor when it is working
properly?
(b) What must be the resistance of your custom-built resistor so
that the potential difference across the motor is 20V?
(c) If you built your resistor from aluminium wire with diameter of
0.03mm and a resisticity of 2.65*10^-8 Ohmes meter, what length of
wire must you use to create the necessary resistance of R1?
(d) What is the ratio of the power used by the motor to the power
dissipated by the resistor, P(motor)/P(R1)?

Consider two production lines with fraction of nonconformities in accordance with LSL, USL.
Production Line 1
|
P1=0.2 |
Production Line 2
|
P2=0.2 |
Consider Production Line 1, Nonconformities occur in productions according to a Poisson distribution. A random sample of 100 products contains a total of 11 nonconformities. Do Hypothesis test for Lambda equal 15% at Alpha 1%?
