Consider the following three vectors: A⃗ =(2,−1,1),
B⃗ =(3,0,5),
and
C⃗ =(1,4,−2).
Calculate the following combinations. Express your answers as ordered triplets [e. g., (9,4,−2)].

Part B

B⃗ +C⃗ =

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud
