What are the negative effects of infrared? IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. Can infrared radiation kill you? Infra-red light affects […]
How do you survive freezing temperature without heat?
How do you survive freezing temperature without heat? Here are a few tips to stay warm and happy this winter with no heat: Reduce as much heat loss as possible. Put blankets over all the windows and outside doors, and bean bag draft busters at the base of every door. Adding Insulation Supercharges Your Walls. […]
How do you protect a Mosfet from a short circuit?
How do you protect a Mosfet from a short circuit? The voltage across the internal resistance can be sensed using simple comparator or even a transistor, which switches on at a voltage of around 0.5V. You can thus avoid the use of a sense resistor (shunt), which usually produces an undesirable extra voltage drop. The […]
Is buoyant force constant?
What are the rules for a series circuit?
What are the rules for a series circuit? In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a […]
Which of the following accurately describes what makes a material a good conductor?
Which of the following accurately describes what makes a material a good conductor? When discussing what makes a material a good conductor you say, “They must resist neutron flow.” readily accept electron flow.” readily accept neutron flow.” resist electron flow.” If you are looking for a material that is a good conductor, you will look […]
How do rocks handle stress?
How do rocks handle stress? Rocks have three possible responses to increasing stress (illustrated in Figure below): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks. What causes rocks to […]
What are the three types of pain receptors?
What are the three types of pain receptors? Within the central nervous system, there are three types of opioid receptors which regulate the neurotransmission of pain signals. These receptors are called mu, delta, and kappa opioid receptors. What are the two types of pain fibers? Each of the spinal nerves emerging from the spinal cord […]

What are the factors affecting the height of the waves?
What are the factors affecting the height of the waves? Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or […]
