Answer:

Crust

Explanation:

Rock is a solid mass, a collection of minerals which occur naturally. There are three different types of rocks- Igneous, Sedimentary and Metamorphic. These vary in texture and composition. The rocks come from the upper most layer of the Earth- the crust. Heat, pressure, volcanoes, wind and water play important role in formation of rocks.

Misha Larkins [42]

Answer:

E =17,280 J

Explanation:

Since the voltage drops linearly from 6V to 4V, the average is 5V. The energy delivered is .

V is the average of initial and fianl voltage

A is the current passing

t is the time in which current is passed

E=V*A*t = 5*0.015*(64*3600) = 17,280 J

Answer:

$R=803k\Omega$

Explanation:

We have the following information,

$V_0 = 12V\\V=10V\\c= 1.25*10^{-6}F\\t=1.8s$

We apply the equation for capacitor charging the voltage across it,

$V=V_0 (1-e^{-t/x})\\e^{-t/x}=1-(\frac{V}{V_0})\\-\frac{t}{Rc}=ln(\frac{V}{V_0})\\R=-\frac{t}{ln(\frac{V}{V_0})*c}$

Replacing values,

$R=-\frac{1.8}{ln(10/12)*1.25*10^{-6}}$

$R=803k\Omega$
