This question is incomplete, but I can do it for you, considering the equation to be *In its most famous form*:
A+B⇒C+D
A and B here are the reactants, while C and D are the products.
The reactants are generally the input materials in the beginning of any chemical reactions and they usually, if not always, are on the left hand side of the chemical equation. While the products are on the right hand side and are the final output of the chemical reaction.

Hope this helps.

Calculate the change in potential energy of a 91.2 kg man when he takes an elevator from the first floor to 37th floor, if the d

MAXImum [283]

Answer:

128379.69 J

Explanation:

Potential energy: This can be defined as the energy of a body to to position in the gravitational field. The S.I unit of potential energy is Joules (J).

The expression for potential energy is given as,

ΔEp = mgΔH

ΔEp = mg(H₂-H₁)..................... Equation 1

Where ΔEp =change in Potential Energy, m = mass of the man, g = acceleration due to gravity, H₂ = Height of the 37th floor, H₁ = height of the first floor

Given:m = 91.2 kg, g = 9.8 m/s², H₁ = 3.99 m, H₂ = 3.99×37 = 147.63 m.

Substitute into equation 1

ΔEp = 91.2(9.8)(147.63-3.99)

ΔEp = 893.76(143.64)

ΔEp = 128379.69 J.

Answer:

A) determine magnetic fields

For 0 ≤ r ≤ a

Magnetic field = ∅ $\frac{rI}{2\pi a^2}$

For a ≤ r ≤ b

Magnetic field = ∅ $\frac{I}{2\pi r}$

For b ≤ r ≤ c

Magnetic field in the region = ∅ $\frac{I}{2\pi r} [ c^2 - r^2 / c^2-b^2 ]$

For r ≥ c

magnetic filed in the region = 0

B ) attached below

Explanation:

<u>A) Determine the magnetic field in the following regions</u>

i) For 0 ≤ r ≤ a

Magnetic field = ∅ $\frac{rI}{2\pi a^2}$

attached below is the detailed solution

ii) For a ≤ r ≤ b

Magnetic field = ∅ $\frac{I}{2\pi r}$

attached below is the detailed solution

iii) For b ≤ r ≤ c

Magnetic field in the region = ∅ $\frac{I}{2\pi r} [ c^2 - r^2 / c^2-b^2 ]$

attached below is the detailed solution

iv) For r ≥ c

magnetic filed in the region = 0 and this is because the net current enclosed in the region = 0

How long does it take from the new moon phase to the first quarter phase

Fynjy0 [20]

The complete cycle of Moon phases takes 29.53 days.

The "First Quarter" has that name because it's one quarter of the time
from one New Moon until the next one.

So that's always close to (0.25 x 29.53) = 7.38 days ... essentially 1 week.
