Answer:
Explanation:
Distance between proton and electron = r = 5.5 x 10⁻¹³ m
Magnitude of charge on electron and proton = 1.67 x 10⁻¹⁹ C
To find their initial acceleration first force between them is:
Initial acceleration of electron and proton are found using
F=ma
a=F/m
Answer: D
X and Y
Explanation:
X The least amount of magnesium Took in magnesium
Y Slightly less magnesium than the cell Took in magnesium
Because active transport occurs when ions or molecules move from less concentration region to high concentration region through semi membrane with the help of some energy.
If we use the sun as a distant object to calculate the convex lens's focal length, we obtain a number that is more closely related to the actual convex lens value.
We need to learn more about a convex lens's focal length in order to locate the solution.
<h3>Why, if we concentrate the sun, do we obtain a focal length that is closer to the correct value?</h3>
- An optical system's focal length is a measurement of how sharply the light converges or diverges.
- The distance between the convex lens's pole and its focus is known as its focal length.
- Convex lenses focus all of the rays from the distant object at their focal point to create a true image.
- We receive a crisper image if the object is farther away from the lens.
- Away from the focal point, an image will form if we concentrate on a neighboring window.
- To get the focal point on a distant tree, we must move the screen in the direction of the lens.
We can therefore draw the conclusion that if we use the sun as a distant object, we will obtain a value that is closer to the convex lens's actual value.
