<span>Car B has a greater momentum than car A.
Since, momentum = mass * velocity
mass of both car A and B is same, velocity of B is greater than A.
So, momentum of car B = 1200 * 25 = 30,000 kg-km/h is greater than </span>momentum of car A = 1200 * 22 = 26400 kg-km/h
Answer:
a) Osmolarity measures the moles of solute per liter of solution.
Explanation:
Osmolarity is defined as the number of moles of solute that contribute to the osmotic pressure, per liter of solution, of solution. That is, the measurement of the solute concentration. The prefix "osmo-" indicates the possible variation of the osmotic pressure in the cells, which will occur when the solution is introduced into the body.
First we need to turn Aouita's time for the race into seconds. There are
60 seconds in a minute, so 7 minutes and 29.45 seconds is (7 x 60) +
29.45 = 449.45. He ran 3000 meters in that time, so his average speed
was 3000 meters divided by 449.45 seconds. 3000 / 449.45 = 6.67 m/s. So,
on average, he covered 6.67 meters (more than 21 feet!) during each
second of the race.
