Is liquid a good conductor of electricity? Substances which allow easy flow of electric current through them are known as electrical conductors. Metals, graphite and certain liquids are a few examples of good conductors of electricity. What liquids are non conductive? Pretty much any oil or organic liquid is non-conducting. These include: Mineral oil. What […]
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 can you determine when searching ahead of you?
What can you determine when searching ahead of you? Scanning helps you to see problems ahead that may cause you to change speed or roadway position, such as vehicles and people that may be in the roadway or signs warning of problems ahead. Look ahead –In order to avoid emergency braking or steering, you should […]

Is the moon dying?
Is the moon dying? The moon isn’t “dead” after all. Newly discovered ridges on the moon’s surface are leading scientists to think that the moon might have an active tectonic system. These ridges, speckled with boulders, could be evidence that, not too long ago, tectonic activity broke apart the moon’s surface. Is Moon cracked? In […]
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 […]
What is the first thing that takes place in the condenser?
What is the first thing that takes place in the condenser? The superheat must be removed first before the refrigerant can condense. This occurs in the first portion of the condenser known as the desuperheating section. What is the primary and secondary purpose of the condenser? 2. What is the purpose of the condenser in […]
What is the kinetic energy of a 10 kg object that is moving with a velocity of 5 m s?
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. […]
