When water evaporates of your body it cools you down, hence why after a shower when the water droplets begin to evaporate you feel cold
Answer:
Explanation:
The 4 wires are connected in series: this means that the same current flow through them, and the voltage of the battery, V0, is equal to the sum of the voltages on each individual resistor:
Also, the equivalent resistance of the series circuit is
The voltage V2 across wire 2 is given by Ohm's law:
(1)
where I is the total current in the circuit, which is given by:
Substituting this into eq. (1), we find an expression for V2:
The second one is hope this helps
Answer:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.
Explanation:
<h3><u>Answer;</u></h3>
Carbonates
<h3><u>Explanation;</u></h3>
- Giant cave systems have formed through the reaction of acids with carbonates the that make up limestone.
- <em><u>Caves are formed as a result of dissolution of limestone, through a type of chemical weathering known as carbonation. This happens when rainwater picks up carbon dioxide from the air and as it percolates through the soil, resulting to the formation of weak carbonic acid. </u></em>
- The weak carbonic acid formed then slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
- Largest caves are formed at a place where the water flows onto the limestone from an adjacent impermeable Portishead formation and Avon Group mudstones.
