In theory, an infinite number of images is formed.
Now, you would notice that the images keep becoming smaller and smaller. At a certain image, due to the inaccurate position of the mirrors(it is impossible to place them exactly parallel to each other in practice), the small image will be distorted and not detected by the eye.
Another factor is that real mirrors are not actually perfect reflectors... With each reflection, a bit of light is lost, so the reflected object becomes dimmer and dimmer until it can no longer be seen.
What are the elements present in water?
Water is composed of may molecules each of which is made up of two hydrogen (H) atoms and one oxygen (O) atom, giving the formula H2O.
What is changed or manipulated during an experiment while keeping other factors constant?
the independent variable
It is best to wait until the end of the experiment to record your observations?
No, absolutely not. You should be making observations as you go, and recording them. Then, when the experiment is over you can draw conclusions, but if you wait till after to record your observations, you won't remember them all.
What is a catchy name for a science fair project having to do with Radio Waves?

Why would ten scientists all conduct the same experiment?
The more scientists that conduct the same experiment, with the same results, the more the findings can be trusted. Also, more scientists are more likely to come up with variances or solutions due to different ways of thinking and approaching things.
Whether a therapy cat has visited the patients would be the independent variable. A secondary independent variable, not as readily noticeable in this question, is whether the patients saw, touched, or otherwise interacted with a therapy cat or cats.
For example, 6 patients out of 100 patients visited by the cat were sleeping; those 6 patients never saw, touched, or interacted with the cats. The sample could not include those 6 patients.
Further, other variables would also be independent and need to be accounted for, including:
- the patient's mobility; the benefits would be harder to assess with a paralyzed patient
- the patient's mental state; the benefits would be harder to assess with a patient who is having active hallucinations or severe dementia
- the patient's medications; a patient given sedative medications would not be alert to see or interact with a therapy pet
- And, the exact behaviors being studied need to be pre-defined in order to properly assess the "outcomes".
So that no extra moles of NaOH were present in the flask.
What happens if you pour water into a jar full of marbles?
When you poor water into a jar full of marbles, the water will fill the spaces between the marbles; bubbles will also appear.
What cell breaks down nucleus in the mitosis?

Why is it unwise to put left calcium carbonate back in the bottle?
because once it has left the bottle it can easily become contaminated.
Barium is an Alkaline Earth Metal found in Group 2 of the Periodic Table.

What did Thomson use in his experiments?
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
What does it mean when a student data that was collected from an experimental supports their conclusion?Answer this question…
The body would wiegh more in air than in vaccum because as we know that there many particles in the air and so their weight whether less or more will be considered with it but in vaccum it's opposite.
