The weight of the object is only dependent on the strength of gravity on that particular object.
1) By the inscribed angle theorem, 
2) By the inscribed angle theorem, arc RT measures twice 63 degrees, or 126 degrees.
Answer:
A -60i - 14j
Step-by-step explanation:
u = -9i + 8j
v = 7i + 5j
2u = 2(-9i + 8j) = -18i + 16j
6v = 6(7i + 5j) = 42i + 30j
2u - 6v
(-18i + 16j) - (42i + 30j)
(-18i - 42i) + (16j-30j)
-60i - 14j
