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 v2 = 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. what is the first velocity of the car with one washer at the 0.25 meter mark? m/s what is the second velocity of the car with one washer at the 0.50 meter mark? m/s

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
