To prevent a spike in blood sugar levels, a person may use glycemic index to determine how quickly a food will be digested. The glycemic index is a value which denotes how carbohydrate-containing food affects blood glucose levels. The value is between 0 and 100.
Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolised. They also cause a lower and slower rise in blood glucose.
The correct answer is: Option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.
Explanation:
The formula for the velocity is given as:
velocity = displacement/time;
It tells us how fast an object cover the distance between two points. In other words, we can say that how fast an object moves in unit time.
Acceleration, on the other hand, is defined as:
Acceleration = change-in-velocity/time
In Physics, we use the term "rate" of a certain quantity changes with time. Here that "certain quantity" is "change-in-velocity." Therefore, acceleration is said to be the rate of change in velocity.
Hence, the correct answer is option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.
