<span>PV = nRT
moles of H2 = 1/2 = 0.5
moles of He = 1/4 =0.25
T = 273 + 27
partial pressure of H2
Px1 = 0.5x0.083x300
P=12.45 atmospheres
PP of He
px1 = 0.25x0.083x300
P =6 22 atmospheres
Totla pressure = 6.22 + 12.45 = 18.68 atm</span>
Answer:
28.2 m
Explanation:
Applying,
Pythagoras theorem,
a² = b²+c²............... Equation 1
Where a = The distance from my starting point to my current point, b = distance walked due west, c = distance walked due south
From the question,
Given: b = 13 m, c = 25 m
Substitute these values into equation 1
a² = 13²+25²
a² = 169+625
a² = 794
a = √794
a = 28.18 m
a ≈ 28.2 m
1 volt = 1 joule per coulomb.
Current doesn't actually pass 'through' a battery.
But if it did, then each coulomb would gain or lose 6 joules in traversing 6 volts, depending on its sign, and whether it climbed or fell.
Answer:
its point Y because the dot that represents Y is cose to s and can make a chan reaction
And return to their normal position after the wave passes.
