If v = 10v, what value of r would limit i to 10ma? (if you have 10 volts, what resistance would be needed to limit the current to 10 milliamps)

Explanation:

The relationship between voltage, resistance and current in a circuit is given by Ohm's law:

where

V is the voltage

R is the resistance

I is the current

In this problem, we have:

V = 10 V

R = ?

I = 10 mA = 0.010 A

Therefore, we can re-arrange the equation to find R:

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 .
