Various food items (derived from plants and animals) are protein rich but some have protein higher than the others and thus these food items are considered as high protein rich food. For example - lean meat and skinless poultry, eggs , legumes, nuts and seeds etc. are all good source of proteins. These sources of food also have vitamin, calcium and carbohydrate but since they have more of protein than other food item thus they are considered good source of protein only. While several other food items are good sources of vitamin, calcium and carbohydrates.
Explanation: <u>Average</u> <u>Velocity</u> is vector describing the total displacement of an object and the time taken to change its position. It is represented as:
At t₁ = 1.0s, displacement x₁ is:
x(1) = 28
At t₂ = 4.0s:
x(4) = 73
Then, average speed is
v = 15
The average velocity of a car between t₁ = 1s and t₂ = 4s is 15m/s
If you mark off a beginning time and ending time on the graph, then the area under the part of the graph between those limits is the distance covered during that period of time.
