Un peso da pesca di 100 g è tenuto in rotazione su un piano orizzontale da un filo di nylon lun-
go 1,2 m. Il pesetto compie un giro in 0,40 s.
Calcola:
• la frequenza del moto;
• l'accelerazione centripeta cui il pesetto è sot-

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
