anna, do you know, in response, the surname seemed familiar, i answered the brest rutherford option,changed in physics, if i'm not mistaken angelina, how did you answer, i answered a variant of three surnames, two seemed familiar to me, but if i remember correctly from the physics course for like, the eighth grade rutherford's experience was something else. well, according to our data, this information is in the textbook on chemistry for the eighth grade, but well, okay, the correct answer to this question is the brest rutherford variant. let's move on to the ninth question since pluto was discovered. he made approximately one-third of the revolution around the sun b1 vice versa around the sun c3 revolutions around sun time xenia maybe i'm not strong in astronomy and generally not geography, not astronomy. it's not mine, so i know the name of the planet pluto more from that. i don't know anything, no option. they chose my unspoken rule if i didn't know the answer. i choose option b, so one is vice versa around the sun and plato is planetary for us now. well, now, probably, there is n
