1. a camcorder has a power rating of 19 watts. if the output voltage from its battery is 7 volts, what current does it use?answer units 2. a 1.5m wire carries a 6 a current when a potential difference of 57 v is applied. what is the resistance of the wire? yourunits 3. a clothes dryer uses about 2 amps of current from a 240 volt line. how much power does it use? yourunits 4.

1.p=VI
p=power(watt)
V=volt
I=current
p=19
V=7
I=?
I=p/v
I=19/7
I=2.71 Ampere

2.V=IR
R=V/I
R=?
V=57
I=6
R=57/6
R=9.5ohm

3.P=IV
p=?
I=2
V=240
p=240x2
p=480watt

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
