A1.5m wire carries a 8 a current when a potential difference of 96 v is applied. what is the resistance of the wire? answer and units? !

I dont know why the length is given unless there is a second part to the problem, but Resistance = Potential difference / Current.

So:

V= 96 volts

I= 8 amps

R = 96/8

R= 12 ohms

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

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 .
