Write your answer to the following problems with the appropriate number of significant figures. (a) 6.85 × 10−5 m + 2.7 × 10−7 m (b) 702.35 km + 1897.648 km (c) 5.0 m × 4.3 m (d) (0.04/π) cm (e) (0.040/π) m Solve the following problem and express the answer in meters with the appropriate number of significant figures and in scientific notation: 3.08 × 10−1 km + 2.00 × 103 cm The intensity of the Sun's radiation that reaches Earth's atmosphere is 1.4 kW/m2 (kW = kilowatt; W = watt). Convert this to W/cm2. An equation for potential energy states U = mgh. If U is in joules, with m in kg, h in m, and g in m/s2 find the combination of SI base units that are equivalent to joules.
