What the right foods for people over 90 years old?
Light food like porridges, cornflakes, light snacks, sandwitches are best recommended for old people over 90yrs. Their digestive system is very weak at this age and having light food makes it easy for digestion. But you cannot compel old people to have light food. Some old people have regular food just like any other individual of all ages, while some others would prefer to have a light diet.
What is the main function of the pupil of the eye?
The pupil serves two important functions - to control the illumination in the eye, and to improve the optical quality of the image on the retina. The first function is obvious - the smaller the hole, the less light gets in. It therefore serves to regulate the light level within the retina. The second function is very important because as the pupil gets larger, more aberrations are created and the image on the retina gets "messier". People with no iris (aniridia) have very poor visual acuity because the eye can't get a sharp image, both because there is to much light (over-saturation) and because there are lots of optical aberrations present. One final function of the pupil is to increase depth of focus, similar to an aperture stop on a camera. This basically increases the range (distance) over which things appear sharp.
What are the best exercises recommended for elderly people that want to stay in shape?
For elderly people, simple exercises such as light jogging or powerwalking can be good to keep the lungs strong. As far as strength, push-ups can be very effective.
Can menopause be stopped once it has started?
Menopause is a natural biological process that cannot be reversed or stopped once it has started. Hormone replacement therapy can help manage symptoms of menopause, but it does not stop the process itself. Consulting with a healthcare provider can provide guidance on managing symptoms and health during this transition.
Why do your pupils constrict?
Pupils constrict in response to bright light to reduce the amount of light entering the eye and protect the sensitive retina from potential damage. Conversely, pupils dilate in dim lighting conditions to allow more light into the eye for improved vision in low-light environments.
What is very light light but can't be lifted?
air
What floats on water but not even a thousand men can lift?
A piece of paper floats on water but cannot be lifted by a thousand men as it is too light.
Is there a weight that cannot be lifted on earth?
ellie mcdonald can not lift 200 grams
What does a quantum look like?
A 'quantum' is a very very very small, but discrete amount of something. For example a quantum of light is called a photon, you cannot get a smaller 'piece' of light than one photon.
What properties of light cannot be described by using the wave model of light?
The particle nature of light, as described by the photon theory, cannot be fully explained by the wave model of light. The wave model also cannot account for certain phenomena such as the photoelectric effect and the behavior of light in very small scales, which require a particle-like description of light.
What is the synonym for heavy?
light, rough, difficult , lifted
Why does a hurricane push over a wall and a light breeze cannot?
Hey!!!! Ummm this might not be the best answer but, A Hurricane, Cyclone or Typhoon (they are all the same thing, just different names) are a very very powerful and strong storm. Where as a light breeze is not... A Hurricane could lift you of your feet while a light breeze cannot. As i said not the best answer but i ! =]
How can you prove that light travels very quickly?
To prove that light travels very quickly, first, you need a flashlight. Because a flashlight is giving off light into a focused circle, it is still light. If you turn on the flashlight, as soon as you hit the switch or button, the circle of light at the other end shining on something appears instantly. You cannot catch the light in motion towards the surface the light is being aimed onto, and because light travels so fast, that is why you cannot see the light between the flashlight and the light on a surface.
What is the relationship between diffraction and the wavelength of light?
the wavelength is very small,so light wave cannot bend very much by diffraction unless it passes through a narrow opening.light waves cannot diffract very much around big obstacles such as buildings.but light waves can always dffract a small amount
What is the heviest weight a kid has lifted?
The most weight ever lifted by a kid younger than 5 is 30 pounds. This child was a very strong kid.
Why are hoods of car ussually made of light materials?
Because they are to be lifted by hand to expose the engine.
What is light but can not be lifted?
