A small but heavy lead weight is attached to a lightweight string with a length of 0.55 m. Determine the natural period of the lead weight if it oscillates with a small amplitude on the end of the string.

The natural period is 1.49 s

Explanation:

T = 2πsqrt(L/g)

T is the natural period

π = 3.142

L is length of the string = 0.55 m

g is acceleration due to gravity = 9.8 m/s^2

T = 2×3.142sqrt(0.55/9.8) = 6.284sqrt(0.05612) = 6.284×0.237 = 1.49 s

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.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
