is this solution?
A) Violet B) Orange C) Green D) Blue
A) Violet B) Orange C) Green D) Blue
1 answer:
Response:
For a transition metal complex in solution exhibiting an absorption peak at 450 nm, which falls within the blue section of the visible spectrum, the corresponding (complementary) color of this solution is orange (option B).
Rationale:
The amount of UV-visible light absorbed indicates that some electromagnetic radiation successfully passes through the sample and is perceivable by the human eye. Thus, the color apparent in the visible spectrum of a complex aligns with the wavelengths of light it allows to pass rather than those it absorbs. The color that is absorbed will be complementary to the one that is transmitted.
In the accompanying image, you can view the associated wavelengths alongside their respective colors. By identifying the wavelength associated with the absorbed color, you will be able to see the complementary color that is visible or reflected.

Answer:
17 m/s south
Explanation:
Mass of the dog = 10 kg
Mass of skateboard = 2 kg
v = Combined velocity = 2 m/s
Velocity of the dog = 1 m/s
Velocity of skateboard
In this scenario, linear momentum is conserved
The speed of the skateboard post-dog jump will be 17 m/s south, considering north as the positive direction
Part a) The connection between the electric field and the magnetic field in an electromagnetic wave is
where
E signifies the strength of the electric field
B indicates the strength of the magnetic field
c represents the speed of light
Using the equation, we determine:
Part b) The text does not clarify the orientation of the magnetic field on the y-axis: I speculate it points in the y+ direction.
The direction of the electric field can be established using the right-hand rule, which states:
- the index finger shows the direction of E
- the middle finger indicates the orientation of B
- the thumb reveals the propagation direction of the wave
Because the wave propagates in the x+ direction, and the magnetic field in the y+ direction, we conclude that the electric field direction (index finger) must be z-.
