<span>F x L = W x X whereW=weight is total load = 80, L is length from fulcrum which is the unknown and what we are solving for. x= length we know. and F equals 50 force we know. So (W*X)/F=LL equals 64</span>
The photosynthesis equation is :
H2O + CO2 + sunlight (energy) > C6H12O6 + O2
So water (H2O) and carbon dioxide (CO2) are the raw materials need for photosynthesis.
Answer:
3.03e-19 J
Explanation:
Use the formula E = hc/λ
Where:
h (Planck's constant) = 6.626e-34 J*s
c (speed of light, constant) = 3.00e8 m/s
λ (wavelength) = 656e-9 m
E = energy (in Joules)
E = (6.626e-34 * 3.00e8) / 656e-9 = 3.03018293e-19 = 3.03e-19 J
Answer:
yes it is important.
Explanation:
It is important to study the climate of other planet to understand the climate of the earth because it is useful to know which things are harmful for our earth and which are important for our earth climate comparing with the other planets.
Answer:
[OH⁻] = 1 × 10⁻¹¹ mol/dm³
Explanation:
Since the hydronium ion concentration of the gastric fluid is [H₃O]⁺ = 1.0 × 10⁻².
The pH at this point is pH = -log₁₀[H₃O]⁺ = -log₁₀[1.0 × 10⁻²] = 2
When milk of magnesia is added, the pH increases by one unit, so the new pH is 1 + 2 = 3
Since pH + pOH = 14, then pOH = 14 - pH = 14 - 3 = 11
The hydroxide ion concentration of the fluid is gotten from
pOH = -log₁₀[OH⁻]
11 = -log₁₀[OH⁻]
-11 = log₁₀[OH⁻]
taking antilog
[OH⁻] = 1 × 10⁻¹¹ mol/dm³
