1. Grupând rezistoare în serie, se poate afirma că: a) rezistenţa echivalentă este mai mică decât oricare dintre rezistenţele rezistoarelor din circuit; b) inversul rezistenţei echivalente este egală cu suma inverselor rezistenţelor rezistoarelor grupării; c) intensitatea curentului electric care trece prin rezistenţa echivalentă este egală cu suma intensităţilor curenţilor care trec prin fiecare rezistor; d) intensitatea curentului electric are aceeaşi valoare prin oricare rezistor.

graph question answered .. you think better when you are relaxed and happy

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
