Ellie has two wire circuits, each connected to its own 6 v battery. one circuit has a resistance of 0.80 ω. the other circuit carries a 4.5 a current. which circuit has greater resistance?

The second circuit with 4.5 A current has more resistance.

Explanation:

potential difference= 6 V

resistance of first circuit=0.80 Ω

for second circuit, current= i=4.5 A

using Ohm's law V= i R

6=4.5 R

R=1.33 Ω

So the second circuit has a greater resistance.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
