Answer:
V for dry skin = 41.83 volts
V for wet skin = 0.196 volts
Explanation:
The relationship between current and voltage is given as follows by Ohm's Law:
V = IR
where,
V = voltage
I = Current
R = Resistance
FOR DRY SKIN:
V = Vd = ?
I = 89 μA = 89 x 10⁻⁶ A
R = 4.7 x 10⁵ Ω
Therefore,
Vd = (89 x 10⁻⁶ A)(4.7 x 10⁵ Ω)
<u>Vd = 41.83 volts</u>
FOR WET SKIN:
V = Vw = ?
I = 89 μA = 89 x 10⁻⁶ A
R = 2200 Ω
Therefore,
Vd = (89 x 10⁻⁶ A)(2200 Ω)
<u>Vd = 0.196 volts</u>
I think it's C. if we're talking about a rover.
But if it's a rocket that's computerized and automatic (synonym of unmanned)... Then it's B.
Answer:
seconds
Explanation:
T = 1 / f
where T is the period and f is frequency.
Here the frequency is 512 Hz.
<em>Using the formula:</em>
T = seconds
Answer:
Explanation:
Rocks tell us a great deal about the Earth's history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.
