An igneous rock contains one half of its original amount of potassium 40 the age of the igneous rock is closest to what
Murrr4er [49]
So we want to know what is the age of igneous rock if it contains one half of its original amount of potassium 40. The half-life of potassium 40 is 1.251*10^9 years. Since in the igneous rock there is one half of potassium left it means only one half-life has passed. And its age is 1.251*10^9 years or 1.251 billion years.

A capacitor that is initially uncharged is connected in series with a resistor and a 407.1 Vemf source with negligible internal
Vlad [161]

Answer:

Resistance, R = 478.9 k\ohm

C = 12.95\micro F

Given:

V = 407.1 V

Current through the resistor, I = 0.850 mA = 0.850\times 10^{-3}

Time constant for the circuit, \tau = 6.20 s

Solution:

Initially the capacitor is uncharged, the current in the circuit remains same.

Thus

At t = 0

the current in the circuit, I = \frac{V}{R}

Therefore,

Resistance, R = \frac{V}{I}

R = \frac{407.1}{0.850\times 10^{-3}} = 478.9 k\ohm

Now, for calculation of Capacitance, C:

Time constant for the circuit, \tau = CR

6.20 = C\times 478.9\times 10^{3}

C = 1.295\times 10^{- 5} F = 12.95\micro F
