What is the resistance of a 15 ampere current with 8 volts of potential difference?

Resistance = 1.875 Ohms

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Current = 8 Amps

Potential difference (Voltage) = 15 Volts

To find resistance;

Voltage = current * resistance

Substituting into the equation, we have;

15 = 8 * resistance

Resistance = 15/8

Resistance = 1.875 Ohms

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 .

a.   mass number from atomic number
