WebWith unsigned (or no negative numbers) with 8 bits we have: 00000000 - representing 0, the smallest number possible. 11111111 - representing 255, the largest number possible. For a total of 256 possible numbers represented. Whereas with sign magnitude we have: 11111111 - representing -127, the smallest number possible. 10000000 - representing 0. Websubtract A vector from both sides. Now you have B vector = - B vector now add B vector to both sides. Now you have 2 B vector = O vector. Divide by two and you see that B is the zero vector, and thus must have magnitude zero. In vectors, just like the real numbers, the only vector which is its own opposite is the zero vector. ( 7 votes) Flag WebYes, it is possible to have negative velocity when acceleration is positive. Consider a body or an object moving in a negative direction, having a negative velocity and acceleration. If the object slows down, its acceleration vector will be in the opposite direction from its motion, i.e., positive. spanish generator
