Comets are usually formed of ice and other suave debris, while asteroids typically contain metals.
Elements are made up of particles.
Answer:
Precision is good but accuracy is poor
Explanation:
The precision in a measure is about how close is a measured value to each other. In the problem, all measurements are between 15.33 and 15.34cm. Thus, you can say precision is good
And accuracy is about how close are the measured values to the theoretical or real value. The real length of the pencil is 15.85cm. The measurements are not even close of the real value. For that reason, you can sat accuracy of the measurements is poor.
