A blueprint shows a hole of 0.3751 to be drilled. What fraction size drill bit is most nearly equal?
- 3/16
- 5/16
- 3/8
how to solve
If the frequency to a capacitor increases, the current through it
- decreases.
- increases.
- is zero.
if the formula for capacitive reactance is 1/2piFC
then as frequency increases capacitive reactance would decrease
this would in turn allow more current to flow?
An example of a paramagnetic material is
- silver.
- iron.
- glass.
- aluminium.
Surely this is incorrect too.
iron would fall into the ferromagnet group
silver would fall into the diamagnetic group
glass would fall into the paramagnetic group
The average value of 100 volts peak AC is
- 70.7 volts.
- 141. 4 volts.
- 63.7 volts.
I think this might be incorrect.
i assume the question is looking for the rms value?
the formula for rms is -
peak voltage x 0.707
or
peak voltage / 1.414
both formulas give 70.7 as the answer
am i missing something?
When aligning an aircraft for a compass swing, the maximum allowable error is
- 1 degrees.
- 3 degrees.
- 5 degrees.
Why?
