12 FIRST YEAR COURSE IN GENERAL SCIENCE 



5. How long does it take Jupiter? 



6. Compare the distances in miles traversed by the three 

 planets in advancing 90 each. 



7. (a) If the direction from E to S is westward, in what 

 direction is J from Ef (6) In what part of the sky would 

 Jupiter be at sunset? 



8. (a) In what part of the sky would Venus be at sunset? 

 (b) Would it be likely to be visible? Why? 



9. Place X at the point on its orbit where each planet 

 would be three months after the positions indicated in your 

 diagram. 



EXERCISE IV (Textbook 47) 



TO FIND THE VOLUME OF A REGULAR SOLID 



APPARATUS: Centimeter rule, rectangular wooden block. 



DIRECTIONS FOR WORK: Measure the length of the 

 block along the grain on the four sides. Read and record 

 each length to .1 cm. Measure and record the width and 

 thickness in the same way. 



Kind of wood Number of block 



Length Width Thickness 



(1) cm. ' cm. cm. 



(2) cm. . . cm. cm. 



(3) cm. cm. cm. 



(4) cm. cm. cm. 



Sum cm. cm. cm. 



RESULTS 



1. Calculate and record the average length, width, and 

 thickness to the nearest .1 cm. 



2. Find the volume of the block to the nearest centimeter. 

 NOTE. If the average width should work out 4.125 cm., 



record it as 4.1 cm.; if 4.175 cm., record it as 4.2 cm. Since 

 we do not measure more closely than to .1 cm., it is un- 

 reasonable to give the result in hundredths or in thousandths.
