Why is the following situation impossible? a student's dormitory room measures 3.7 m by 3.7 m, and its ceiling is 2.6 m high. after the student completes his physics course, he displays his dedication by completely wallpapering the walls of the room with the pages from his physics textbook which has 960 pages of text on 480, 0.21 m × 0.28 m sheets. he even covers the door and window

Surface area of walls (38.48 meter squares)>the total surface area of 480 sheets(28.224  meter squares) .Thus the given situation is not possible .

Explanation:

Given dimensions of walls of room are

length L=3.7 m

breadth B= 3.7 m

Height H= 2.6 m

Therefore surface area

=>

Dimensions of sheets of book

length l=0.21 m

breadth b=0.28 m

Surface area of single sheet ,

Therefore total surface area of 480 sheets of book is

Since S> A_t  surf,i.e.,ace area of walls of room is much greater than the total surface area of sheets of book, it is not possible to completely wallpaper the walls of the room with pages from his physics text .

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

amplitude

hope this
