Soal Nomor 3:Sebuah peti kayu yang beratnya 80 Newton diletakkan di atas permukaan tanah. Diketahui tekanan yang diberikan peti tersebut adalah 2000 Pa. Berapakah luas bidang tersebut?
Answer (3)
The question seems to be asking about the meaning of a suffix related to the word spectacles . While the suffix in and of itself pertaining directly to spectacles is not described, it does touch on the negative power of lenses used in spectacles for nearsighted people. This negative power indicates a diverging lens, which is thinner in the center and prescribed in diopters.
For eyeglasses, there are no specific suffixes that describe spectacles, however, in English, suffixes such as -less and -ness denote the absence of or the state of something, respectively, and the suffix -ess denotes the female form of a noun. Eyeglass prescriptions for nearsighted individuals typically have a negative power, indicating a diverging (concave) lens to correct the over convergence of light rays in a nearsighted eye.
The suffix in 'spectacles' is '-acles,' which denotes a device related to vision. The root 'spect' comes from the Latin 'spectare,' meaning 'to look or see.' Combined, 'spectacles' refers to eyeglasses intended to aid vision.
