Vector v1-57 n at 30° above the positive x-axis. write down the x and y-components of this vector. 5. vector h has components h-15 n and hy-25 n. what angle does this vector make with the x-axis?

X component of V1 = 49.36 N

Y component of V1 = 28.5 N

Angle is 59 degree

Explanation:

V1 = 57 N at 30 degree above + x axis

X component of V1

V1x = V1 Cos 30 = 57 x Cos 30 = 49.36 N

V1y = V1 Sin 30 = 57 x Sin 30 = 28.5 N

Hx = 15 N

Hy = 25 N

Angle made with + X axis is θ.

Tan θ = Hy / Hx = 25 / 15 = 1.667

θ = 59 degree

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
