Asap pls will mark brainliest to the first correct answer pls ! calculate the first and second velocities of the car with
one washer attached to the pulley, using the formulas
v1 = 0.25 m/t1, and
u2 = 0.25 m/(t2- t1)
where t1 and t2 are the average times the car took to
reach the 0.25 and the 0.50 meter marks. record these
velocities, rounded to two decimal places, in table e.

1. when the tempature rises,your sweat glands and then springs into action making perspiration. some sweat evaporates with your skin taling heat with it.2.some of the blood pumped by the heart travels by your lungs to get rid of carbon dioxide and pick up oxygen.3.saliva produces by, you drinking water which saliva is 98% of. when mucus builds up in your body it also creates saliva as well as, antibacterial compunds.4.when the core body tempature drops, the shivering reflex is triggered to maintain homeostasis. for example: when you get out the pool you start to shiver because it is cold.
