Answer:
b. POST has failed, and you should research the BIOS beep codes.
Explanation:
When we here continuous beeps coming from computer and monitor shows no signal as the computer lost its power. This situation arises when POST( Power on self test) has failed and we must research the BIOS( basis input output system) beep codes.
When the post fails there is not any diagnostic testing sequence Runs to evaluate the correct functioning of the computer keyboard, random access memory, storage devices and other peripherals.
To solve this we use the
equation,
M1V1 = M2V2
<span>where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.</span>
<span>
</span>
<span>3.0 M (50 mL) = M2 (250 mL)</span>
<span>M2 = 0.6 M</span>
