Answer : The correct degree of precision is 272.94 g.
Explanation :
Precision : It is defined as the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 2.7 kg each time. Then the measurement is said to be precise.
Level of precision is determined by the maximum number of decimal places.
In the given figure, the value of mass of object is 280 g. From the given options we conclude that the 272.94 g is more close to 280 g and has maximum number of decimal places. So, 272.94 g measurement is said to be precise.
Therefore, the correct degree of precision is 272.94 g.
Answer:

2.)an object will jot change its motion unless acted on by an unbalanced force
Answer:
A substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.
Explanation:
In visible light spectrum, a combination of red light and blue light gives magenta. Also a combination of red and green lights gives yellow light. and when green and blue lights mix the resulting light color is cyan.
However, if these three primary colors mix in equal proportion, we will have a neural color or white color and in the absence of these primary colors we will have black.
Thus, a substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.
