Maximum possible voltage = Measured value + Uncertainty = 12.0 + 0.2 = 12.2 V.

Fractional error = (absolute error / measured value) = 0.3 / 15.0 = 0.02.

The absolute error is given directly as ±5 V.

Relative error = Absolute error / Measured value = 10 / 1000 = 0.01.

Using the formula for density (density = mass/volume), the uncertainty in density can be calculated using the formula for propagation of uncertainty.

Relative error = (Absolute error / Measured value) * 100 = (5 / 200) * 100 = 2.5%

Absolute error = Relative error * True value = 0.1 * 10 = 1 kg.

Percentage error = (Absolute error / Measured value) * 100 = (1 / 50) * 100 = 2%

5 kilometers is equal to 5000 meters.

There are 100 centimeters in a meter.

There are 1000 millimeters in a meter.

There are 3600 seconds in an hour (60 seconds x 60 minutes).

The measurement 0.004560 has 4 significant figures (the leading zeros are not counted).

Leading zeros do not count, but the trailing zero after the decimal does. Therefore, 0.05060 has 4 significant figures.

The significant figures are 5, 0, and the trailing zero counts, totaling 3.

The number 0.004560 has 4 significant figures (the leading zeros are not counted).

Leading zeros do not count as significant figures. The significant figures in 0.00456 are 4, 5, and 6, which totals to 3 significant figures.

The significant figures are 7, 8, 9, and the trailing zero counts.

The trailing zero after the decimal point counts as a significant figure.

All non-zero digits are significant, so 1002 has 4 significant figures.

5000 has 1 significant figure unless specified otherwise (e.g., 5000. has 4 significant figures).

5000 has 1 significant figure unless specified with a decimal point (e.g., 5000. has 4).

To round 0.0001234 to two significant figures, we look at the first two non-zero digits (1 and 2) and round up, resulting in 0.00013.

To round 0.05060 to three significant figures, we keep the first three significant digits (5, 0, and 6), resulting in 0.0506.

Speed = distance/time = (100000 m)/(7200 s) = 27.78 m/s, approximately 20 m/s.

At 90 km/h, the car will travel 180 km in 2 hours.

Range of possible speeds = Measured speed ± Error = 60 ± 2 gives 58 to 62 km/h.

Leading zeros are not significant. The significant figures are 5, 0, 0, which gives a total of 3 significant figures.

The number 0.0600 m has 3 significant figures. The leading zeros do not count, but the trailing zeros after the decimal point do.

The number 150.0 has 4 significant figures because the trailing zero after the decimal point counts as significant.
