38. You have four solutions of salt water. Solution 1 has 55 g of salt dissolved in 500 mL of water 19 a concentration of 0.21 g/mL. Solution 3 has 36 g of salt dissolved in 144 mL of water. Solutio
concentration of 0.23 g/mL. Which of the following lists the solutions in order from the leastc
the most concentrated?
a 1, 2, 3, 4
c. 1, 2, 4,3
b. 2, 4, 3, 1
d. 3, 4, 2, 1

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.

Yup no bull frogs here man

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
