Does solar power work with artificial light? Solar cells generally work well with natural sunlight, as most uses for solar-powered devices are outdoors or in space. Because artificial sources of light such as incandescent and fluorescent bulbs mimic the Sun’s spectrum, solar cells can also work indoors, powering small devices such as calculators and watches. […]

How do you plot a Bode plot? To draw Bode diagram there are four steps: Rewrite the transfer function in proper form. A transfer function is normally of the form: Separate the transfer function into its constituent parts. Draw the Bode diagram for each part. Draw the overall Bode diagram by adding up the results […]

Why do some sensory receptors adapt quickly? The usefulness of having some receptors that adapt quickly and others that do not is to provide information about both the dynamic and static qualities of a stimulus. Conversely, slowly adapting, or tonic, receptors keep firing as long as the stimulus is present. What is the adaptation of […]

What is the typical composition of solder? The most popular combination is 60% tin, 39% lead, and 1% alloys. This combination is strong, has a low melting range, and melts and sets quickly. A higher tin composition gives the solder higher corrosion resistances, but raises the melting point. What is the composition of lead-free solder? […]

Is a joule equal to one newton meter? One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. […]

What are the four types of crystals? Crystalline substances can be described by the types of particles in them and the types of chemical bonding that takes place between the particles. There are four types of crystals: (1) ionic , (2)metallic , (3) covalent network, and (4) molecular . What is the strongest attractive force […]

How are the pneumatic system and the hydraulic system similar? Pneumatic and hydraulic systems have many similarities. Both pneumatics and hydraulics are applications of fluid power. They each use a pump as an actuator, are controlled by valves, and use fluids to transmit mechanical energy. What is hydrostatic transmission system? The hydrostatic transmission transmits energy […]

How are the 32 bits of an IP address organized in a typical large network? How are the 32 bits of an IP address organized in a typical large network? IP addresses are organized in network Classes A, B, and C depending on the size of the organization. In Class A the first octet is […]

How do you find the resistance of an ac circuit? So when using resistors in AC circuits the term Impedance, symbol Z is the generally used to mean its resistance. Therefore, we can correctly say that for a resistor, DC resistance = AC impedance , or R = Z. How does current flow through a […]

How did the Wright brothers think of the airplane? If others had thought about steering at all, it was by rudder – a marine analogy unworkable in the air. The Wrights saw that control and stability were related, that a plane turned by rolling. Six hundred more glides that year satisfied them that they had […]
