I believe the correct answer from the choices listed above is the second option. The scientific notation of the measurement 0.00000000062 kg would be <span>6.2 x 10^-10 kg. Scientific notation is used to express too large and too small values of numbers. Hope this helps. Have a nice day.</span>

<h2>Answer:</h2>

The scientific form of a number is:

                        =6.2\times 10^{-10}\ kg

<h2>Explanation:</h2>

We are given a number which we have to express in scientific notation.

We know that a number is expressed in scientific notation as follows:

  • There must be one digit before the decimal.
  • If the decimal is shifted to the left then the number of shift takes the positive power of 10 and if the shift is to the right then the number of shift takes negative power of 10.

Here we have a number as:

0.00000000062\ kg

Now we have to shift the decimal 10 places to the right.

Hence, the  number in scientific form is:

     =6.2\times 10^{-10}\ kg

"There are two types of error that can occur when making measurements: systematic and random error. How you correct the error de
Murljashka [212]

Answer:

Systematic error can be corrected using calibration of the measurement instrument, while random error can be corrected using an average measurement from a set of measurements.

Explanation:

Random errors lead to fluctuations around the true value as a result of difficulty taking measurements, whereas systematic errors lead to predictable and consistent departures from the true value due to problems with the calibration of your equipment.

Systematic error can be corrected, by calibration of the measurement instrument. Calibration is simply a procedure where the result of measurement recorded by an instrument is compared with the measurement result of a standard value.

Random error can be corrected using an average measurement from a set of measurements or by Increasing sample size.

8a. What is the equivalent resistance of the following circuit?
ollegr [7]

Answer: Take your pick

Explanation:

if they are all in parallel 1 /(1/100 + 1/300 + 1/50) = 30 Ω

if 50 is in parallel with 2 in series 1 / (1/(100 + 300) + 1/50) = 44.444...Ω

if 100 is in parallel with 2 in series 1 / (1/(50 + 300) + 1/100) = 77.777...Ω

if 300 is in parallel with 2 in series 1 / (1/(100 + 50) + 1/300) = 100 Ω

If 50 is in series with 2 in parallel 50 + 1/(1/100 + 1/300) = 125 Ω

If 100 is in series with 2 in parallel 100 + 1/(1/50 + 1/300) = 142.857...Ω

If 300 is in series with 2 in parallel 300 + 1/(1/50 + 1/100) = 333.333...Ω

If they are all in series 100 + 300 + 50 = 450 Ω
