Why is a 5% NaCl solution hypertonic to red blood cells? The red blood cells in the 5% NaCl was present in an hypertonic solution, so the water rushed out of the red blood cells due to osmosis. There was a higher concentration of solutes in the extracellular fluid (NaCl) than the intracellular fluid. Is […]
What absorbs electromagnetic?
What absorbs electromagnetic? SYCO is a room temperature ferromagnetic material which absorbs magnetic radiation, while carbon black is a readily available highly conductive material. Does rubber absorb EMF? Rubber does block EMF radiations. This has been proved in an experiment where a composite rubber matrix was used to absorb forms of EMF radiations. However, the […]
What are the similarities and differences between basic and applied research?
What are the similarities and differences between basic and applied research? Basic research does not have immediate commercial objectives and although it certainly could, it may not necessarily result in an invention or a solution to a practical problem.

Can a laser Bend?
Can a laser Bend? Five years ago physicists showed that certain kinds of laser beam can follow curved trajectories in free space. The Florida team generated a specially shaped laser beam that could self-accelerate, or bend, sideways. The researchers did not bend the laser beam as a whole but rather the high-intensity regions within it. […]

What type of bonding is found in methanol?
What type of bonding is found in methanol? hydrogen bonding How many H bonds can methanol form? three Is there hydrogen bonding in 1 butanol? a) The 1-butanol can hydrogen bond together, but the ether only has weak dipole-dipole interactions. The 1-butanol therefore has greater surface tension. b) The 1-butanol can hydrogen bond together, but […]
