Final answer:
The Plus-Minus symbol is represented by Unicode, and a negative sign is conventionally assigned to an object moving downward in physics. Option (C)
Step-by-step explanation:
The Plus-Minus symbol is represented in different coding systems. In this context, the correct answer is C) Unicode. Unicode is a universal character encoding standard that includes a wide range of characters and symbols. For the Plus-Minus symbol, you would use Unicode. Both ANSI and ASCII have representations for common characters, but Unicode is more comprehensive and supports a diverse set of symbols, including the Plus-Minus symbol.
Regarding the sign convention for objects moving downward, by convention, b. A negative sign (-) is assigned to an object moving downward in the context of physics and the study of motion. This follows the convention that typically associates downward movement with negative values, especially in the context of gravity and vertical motion.
The standard code for the Plus-Minus symbol is Unicode, and its specific code point is U+00B1. This ensures a standardized representation of the Plus-Minus symbol across a wide range of devices and applications.
Option (C) Unicode is the correct answer for the Plus-Minus symbol's standard code.
