Answer:
they have opposite charges
Answer:
0.37 cm
Explanation:
The image is formed on the retina which is at a constant distance of 2.70 cm to the lens. Therefore, image distance = 2.70 cm.
The object is at a distant of 265 cm to the lens of the eye.
From lens formula,
= 
+ 
where: f is the focal length, u is the object distance and v is the image distance.
Thus, u = 265.00 cm and v = 2.70 cm.
= 
+ 
= 
= 
⇒ f = 
= 0.37
The focal length of the eye is 0.37 cm.

<span>When we see a solid color that is red, blue, or black let's say, it is said to have a high saturation of color. A color that is almost gray has very little or very saturation. Of course, the amount of gray can vary greatly but for the most part a color that is almost gray has little or no saturation at all.</span>
Answer:
B. an inverse relationship
Explanation:
Here is the complete question
Ricardo is on vacation, doing some mountain climbing. He notices that the higher he goes up a mountain, the colder he feels. He remembers his physics teacher teaching about these types of relationships. What is the type of relationship between mountain elevation and temperature? A. a positive relationship B. an inverse relationship C. a neutral relationship D. a direct relationship
Solution
It is an inverse relationship because, as Ricardo's mountain elevation increases, he feels colder. So, as his mountain elevation increases, the temperature decreases.
Since one variable decreases while the other increases, it can only be an inverse relationship.
Let h be Ricardo's mountain elevation and T his temperature. So by inverse proportionality,
h ∝ 1/T
h = k/T
hT = k = constant
So, we have an inverse relationship and B is the answer.
