The distance formula:d = v i · t + a · t² / 2Sir G.: ( v i = 0 )
d G = 0 + 0.3 · t² / 2Sir A. : d A = 0 + 0.2 t² / 288 m = 0.3 t² / 2 + 0.2 t² / 2 / · 2 ( multiple both sides by 2 )176 = 0.3 t² + 0.2 t²176 = 0.5 t²t² = 176 : 0.5t² = 352t = √352t = 18.76 sd G. = 0.3 · 18.76² / 2 = 0.3 · 352 / 2 = 52.8 mAnswer: The knights collide at 52.8 m relative to Sir George`s starting point.
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>
