Answer:
option e = 1.99 × 10⁻⁶ m
Explanation:
Given data:
Mass of electron = 9.11 × 10⁻²⁸ g or 9.11 × 10⁻³¹ Kg
Velocity = 3.66 × 100 m/s
Wavelength = ?
Solution:
Formula:
λ = h / m. v
λ = wavelength
h = planck's constant
m = mass
v = velocity
Now we will put the values in equation
λ = h / m. v
λ = 6.63 × 10⁻³⁴ Kg. m²/s / 3.66 × 100 m/s . 9.11 × 10⁻³¹ Kg
λ = 6.63 × 10⁻³⁴ Kg. m²/s / 3334.26 × 10⁻³¹ Kg .m/s
λ = 1.99 × 10⁻⁶ m
A map scale indicates the size of a mapped area.
Answer:
Here the force is 10N and the mass is 5 kg. Dividing both sides by 5kg, we get a = 2 m/s^2.
Answer:
Equilibrium constant is 0.0873
Explanation:
For the reaction:
A + B ⇄ C
Equilibrium constant is defined as:
K = [C] / [A] [B]
concentrations in equilibrium of each reactant are:
[A] = 10 - X
[B] = 5 - X
[C] = 15 + X
If concentration in equilibrium of B is 9, X is:
[B] = 5 - X = 9 → <em>X = -4 </em>
Replacing:
[A] = 10 - (-4) = 14
[B] = 5 - (-4) = 9
[C] = 15 + (-4) = 11
K = 11 / (14×9) = 0.0873
Thus, <em>equilibrium constant is 0.0873</em>
Answer:
Released into the atmosphere
Explanation:
The carbon that the plant had been storing when it was alive, would be released upon death into the soil
