a hydraulic system multiplies a force by applying the force to a small surface area.the increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area

Yes convex and concave mirrors are also known as spherical mirrors. If mercury coating is made on the convex side of the spherical then mirror is known as concave mirror. If mercury coating is made on the concave side the convex portion would reflect the light fallen so it is named as convex mirror. Actual just a small part of the sphere is taken out and this would act as the spherical mirror.
A kaleidoscope is an instrument with small mirrors pieced together to create a larger, clearer image. As light enters the kaleidoscope, it reflects off the mirrors to create intricate patterns and designs that change as the instrument is turned.
There are many places where one can purchase small mirrors. One can purchase small mirrors at popular on the web sources such as Amazon and Bed, Bath, and Beyond.
thats a hard one, im not sure what the answer is. do you?
yes you can because when the light ray which comes from infinity after reflecting it converge in focas and then large number of heat occur and it burns the paper but paper should be kept in focas
meteorites
Many telescopes do, especially the largest ones.Others use a refracting lens to do that job.(Note: Our entire discussion so far has included a redundant amountof redundancy. All mirrors reflect, and alllenses refract.)
Usually aluminum. It is normally deposited as a vapour to get an incredibly smooth surface. In small home-made telescopes, they use silver.
Early lens telescopes were small, expensive, made from delicate glass, and had fringes of violet color around bright objects. People could make mirrors, first of polished metal, then from glass coated with silver, and finally from different glasses coated with aluminum and other chemicals. These mirrors are larger, cheaper, and reflected light without making the color fringes. The reflecting telescope made modern Astronomy possible.
Small pores on the leaf surface are called stomata. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
