Why do older people often need brighter light to properly see objects?
Ricks?
How are quasars older than the universe?
Of course they aren't. At times, it may have seemed that certain objects in the Universe were older than the Universe, due to wrong estimates about (a) the age of the Universe, or (b) the age of the corresponding objects. But, as more exact calculations become available, these discrepancies are solved. The fact that some objects seemed to be older than the Universe was, precisely, an indication that something was wrong in the age calculations.
What is the definition of strata?
Strata are the layers of the earth. The deeper the layer, the older the objects that are found in the layer will be. Archaeologists use this as a common way to date objects.
What causes farsightness in older people?
The cause of farsightedness in older people is that theirs lenses become relatively brittle. Therefore it becomes difficult for them to focus, especially on nearby objects.
Any method of determining whether an event or object is older or younger than other events or objects?
fossil
Why do you see objects in space older than they really are?
You don't see the objects themselves, but rather the light that has reflected off of them. That reflection travels toward us at the speed of light, and with enough distance we will see the object as older due to the amount of time it takes for the reflected light to reach us.
When archaeologists study an excavation site objects found closer to the surface are?
Not as old as those found deeper
What decreases to the lens as you get older?
The flexibility of the lens decreases as you get older, leading to difficulty in focusing on close objects, a condition known as presbyopia. This is a natural part of the aging process and usually becomes noticeable around the age of 40.
Why is potassium 40 used to date objects older than 50 000 years old?
Potassium-40 is used for dating objects older than 50,000 years because its half-life is about 1.3 billion years, allowing for dating of older materials. When potassium-40 decays to argon-40, the amount of argon-40 trapped in a sample provides a way to estimate the sample's age. This method is particularly useful for dating rocks and minerals.
Would Carbon-14 or Uranium-235 be better to date a fossil from the Precambrian time?
uranium-235 dates older objects so uranium-235 would be your answer
What can scientists discover by counting the number of craters on a surface?
Scientists can discover the relative age of two objects by counting the number of craters on their surfaces. The longer an object has been in space, the more craters it should have. Comparing the number of craters on two objects in space will determine which is older.
Does motion enhances older infants attention to an objects surface features?
Yes, motion can enhance older infants' attention to an object's surface features by drawing their focus and engaging their visual processing. The dynamic nature of motion can make the object more salient and increase interest and exploration. This heightened attention can help with visual and cognitive development in older infants.
