A uniform meter stick with a mass of 180 g is supported horizontally by two vertical strings, one at the 0-cm mark (with tension T1) and the other at the 80-cm mark (with tension T2). A small pentagonal object of mass = 50g is placed at the 60cm mark. Required:
a. Draw a picture showing all forces acting on the stick (do not forget the weight of the meter stick).
b. Calculate the tensions in the strings at the 0-cm and 80-cm mark by choosing the pivot point at T1.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
