Given ()=52+1 and ()=2−3. Olivia was asked to find (()). She showed the following work:

Line 1: (())=(2−3)

Line 2: =522−3+1

Line 3: =522−2

This answer is incorrect. Answer the following questions:

On which line did Olivia make a mistake? Justify your answer.
Now show the correct way to solve this problem, showing all work like Olivia did above.

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
