ElenaW [278]

Answer:

The current drawn by Horace’s reading glasses is 0.8 A.

Explanation:  

Given that,

Resistance of each bulb, R = 2 ohms

Voltage of the system, V = 3.2 volts

These two bulbs are connected in series. The equivalent resistance will be 2 ohms +2 ohms = 4 ohms

Let I is the current drawn by Horace’s reading glasses. Using Ohm's law to find it such that :

V=IR\\\\I=\dfrac{V}{R}\\\\I=\dfrac{3.2}{4}\\\\I=0.8\ A

So, the current drawn by Horace’s reading glasses is 0.8 A.

Answer: ok  well first when Horizontal faults, like vertical faults, disturb the formation of the earth's layers and cause irregularities, including tilting. Surface fault ruptures can also cause tectonic subsidence, which is broad tilting of the valley floor.  that is What causes the disturbance of rock layers to collapse what  and then Due to an unconformity, the ______ period is missing from the rock layer record. The principle of lateral continuity proposes that sedimentary rock layers it provided a tool for sorting out the relative timing of various geologic events  must have been moved into that position by crustal disturbances after their deposition.
