B. Write the number of significant figures in the following data. 1. When the moon is at its farthest distance from Earth, known as apogee, it is about 405,500 km from our planet. 2. Temperatures on Mercury are extreme. During the day, temperatures on the surface can reach 800°F. 3. Earth's average distance from the Sun is about 150,000,000 km. KNOT
Answer (1)
Here's a breakdown of the number of significant figures in each data point: 1. 405,500 km- Number of significant figures: 4- All non-zero digits are significant.- The trailing zeros are ambiguous. Since there's no decimal point, we assume they are not significant. 2. 800°F- Number of significant figures: 1- Trailing zeros in a whole number without a decimal point are not significant. 3. 150,000,000 km- Number of significant figures: 2- All non-zero digits are significant.- The trailing zeros are ambiguous. Since there's no decimal point, we assume they are not significant.
