Calculate the first and second velocities of the car with three washers 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, to two decimal places, in Table E. What is the first velocity of the car with three washers at the 0.25 meter mark? 0.28 m/s What is the second velocity of the car with three washers at the 0.50 meter mark? 0.56 m/s

explanation:

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
