Două mobile se mişcă rectiliniu şi uniform, după legile x1= 2·t + 5 şi x2=-2·t +9. Momentul de timp (exprimat în secunde) la care cele două mobile se întâlnesc este: *

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

When using the scientist method, which step comes last?
