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 […]
Why do black things absorb light?
Why do black things absorb light? Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does […]

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 […]
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 location has the greatest number of hours of daylight?
Which location has the greatest number of hours of daylight? According to records from weather stations across the US, Yuma in Arizona is the sunniest place in the world. During daylight hours, which range from 11 hours in winter to 13 in summer, it has a 90% possibility of sunshine. What angle does the sun […]
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 […]
