At what pressure will the mean free path in room temperature? The mean free path of gas molecules is often used to measure the quality of the vacuum. For example, the mean free path of air particles at room temperature and atmospheric pressure 1013 hPa equals 68 nm . However, if we decrease pressure to […]
Is gravitational force is independent of nature of intervening medium?
Is gravitational force is independent of nature of intervening medium? The gravitational force is a non-central force. The gravitational force is independent of the intervening medium. In other words, the force between two masses remains the same whether they are in air, vacuum, water or separated by a brick wall. The gravitational force is a […]
What happens when iron is mixed with Sulphur?
What happens when iron is mixed with Sulphur? When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and form ferrous sulphide (FeS). It is a new substance which has properties entirely different from Fe and S. Therefore, heating of a mixture of iron and sulphur powder is a chemical […]
What were the negative effects of the steamboat?
What were the negative effects of the steamboat? It was rare for a steamboat to last five years. The years between 1830 and 1839 saw the destruction of 272 steamboats after less than three years of travel each” (“A History of Steamboats”). Steamboats “were also an environmental menace, destroying riverbank ecosystems and contributing to both […]
Why is cycloid faster?
Why is cycloid faster? 6) may seem somewhat sudden. Rather than determining the na- ture of the function according to the calculus of variations, in this case it was already known that the cycloid is the curve of quickest descent because research on cycloids has been devel- oping for a considerable length of time. Is […]

Does a hypertonic solution cause a cell to swell?
Does a hypertonic solution cause a cell to swell? A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage. Where is osmosis found in the body? Osmosis […]

What are the two types of kinase linked receptors utilized by the immune system?
What are the two types of kinase linked receptors utilized by the immune system? All of these proteins act through enzyme-linked receptors that are single-pass transmembrane proteins with a serine/threonine kinase domain on the cytosolic side of the plasma membrane. There are two classes of these receptor serine/threonine kinases—type I and type II—which are structurally […]
