You apply a force of 54 N to a car jack in order to change a tire. Each "Crank" of the jack is exerted over a distance of 64 cm. What is the work input on the car jack? (Hint: 1m = 100 cm)
Step # 1
Step #2
Step #3

Explanation:

Work = force × distance

W = (54 N) (0.64 m)

W ≈ 35 J

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

i need the answer to this too but idk it ; -;
