i am sup by the way. so im guessing i win?
The answer is B. A only. The optimum valve timing is found through experimentation using an engine dynamometer. The timing of the opening and closing of the valves is called valve timing. So the use of dynamometer measures the power output of a machine that is why it can measure the optimum valve timing.
To convert binary fraction to decimal fraction, we first write the given
.1011 (base 2)
The process of conversion is to break down to its decimal constituent,
.1011 (base 2) = (1*2^-1)+(0*2^-2)+(1*2^-3)+(1*2^-4)
.1011 (base 2) = 0.5 + 0 + 0.125 + 0.0625
.1011 (base 2) = 0.6875 (base 10)
<em>ANSWER: 0.6875 (base 10)</em>
You shood just be able to tern it on
