Why should the lens of a normal eye be fatter to look at near objects and thinner to look at distant objects?
The muscles around the lens of your eye push and pull it thicker and thinner to focus your eye on an object depending on the distance from your eye to the object. The focal length of a fat lens is shorter than the focal length of a thin lens (the light rays are bent more sharply) When you focus binoculars, you are adjusting their focal length

How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
Why use heparin with an MI?
Heparin is a blood thinner, and an MI is a blockage in one of the small blood vessels around the heart. By thinning the blood this blockage can often be overcome, allowing normal blood flow to the heart muscle.
Does friction cause more energy to be wasted if the object is heavier Why?
Friction between two objects = C X N. where C is the coeffiecient of friction for the objects in question, and N is the 'Normal' force. The normal force is the force equal and opposite to the object's weight. Therefore, if you increase the object's weight, the friction force increases, and the amount of energy wasted increases.
What 2 things determine the friction between to objects?
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
Why should the lens of a normal eye be fatter to look objects and thinner to look at distant objects?
The lens of a normal eye adjusts its shape to focus light properly on the retina, a process known as accommodation. When viewing nearby objects, the lens becomes thicker (fatter) to increase its curvature, allowing it to bend light more sharply to focus the image. Conversely, for distant objects, the lens flattens (becomes thinner), reducing its curvature and enabling the light to focus accurately on the retina without distortion. This dynamic adjustment ensures clear vision across varying distances.
Why should the lens of a normal eye be fatter to lookat near objects and thinner to look at distance object?
The lens of a normal eye changes shape to focus on objects at varying distances. When looking at near objects, the lens needs to be thicker to refract light properly onto the retina. Conversely, for distant objects, a thinner lens is needed to allow the light to converge properly on the retina for clear vision.
What are the differences in vision between a myopic eye and a normal eye?
A myopic eye, also known as nearsightedness, can see nearby objects clearly but struggles to see distant objects clearly. In contrast, a normal eye can see both nearby and distant objects clearly without any difficulty.
What are the key differences between myopia and normal vision?
Myopia, also known as nearsightedness, is a refractive error where distant objects appear blurry. It occurs when the eyeball is too long or the cornea is too curved. Normal vision, on the other hand, allows for clear vision of both near and distant objects.
What is the name of the condition for someone that requires no corrective lenses to focus on distant objects?
The condition is called emmetropia. This means that the person has normal vision and can see distant objects clearly without the need for corrective lenses like glasses or contacts.
How do you know when your hamster is having a baby?
if it is fatter than normal.
Is the normal resting eye generally set for distant vision?
The normal resting eye can see distant objects, but they do appear blurrier and less colourful. Take mountains for an example. I can see them a province away while I'm on crowfoot, but they look a very light gray. Hope I helped :3
Why do short girls tend to have larger breasts compared to normal height girls?
cos they tend to be fatter :D
How can you tell when a lizard is about to lay her eggs?
she would normally be fatter than normal, ONLY if your feeding her normally, Brand0n
What are the different types of eye ball shapes and how do they affect vision?
There are three main types of eye shapes: normal, nearsighted (myopic), and farsighted (hyperopic). The shape of the eye affects how light is focused on the retina, which can impact vision. Nearsighted eyes are longer than normal, causing distant objects to appear blurry. Farsighted eyes are shorter than normal, making close-up objects blurry. Normal eyes have a balanced shape for clear vision at various distances.
What happens when a persons ventricles have thinner walls then normal?
it breaks more easily
Is it normal for someone to be distant after someone dies?
yep at some stage.
