What is the Y-component of a vector A, which is of magnitude 16-12 and at a 45° angle to the horizontal?

Astate of matter all that has define volume and can flow is a(n)

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.

Give one example to show that when substances are mixed, it may result in a chemical or a physical change depending on the conditions.
