How do you calculate the no load speed of a DC motor? By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and […]
What is considered a significant financial interest SFI that must be reported?
What is considered a significant financial interest SFI that must be reported? A “Significant Financial Interest” (SFI) is the receipt by you, your spouse, or your dependent children of any of the following, if related to your University responsibilities or professional expertise: Income that exceeds $5,000 from any outside entity, measured on a rolling 12‐month […]
What do the arrows in a food chain represent quizlet?
What do the arrows in a food chain represent quizlet? Food chains show which organisms eat other organisms. The arrows represent the direction of the transfer of energy from one organisms to the next. What causes the arrows to move in this direction? The earth’s rotation causes a phenomenon called Coriolis effect. The lower latitudes […]
Which fruit or seed is dispersed by animals?
Which fruit or seed is dispersed by animals? Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks—the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows. What seeds […]
Why is ecological footprint bad?
Why is ecological footprint bad? The ecological footprint is a measure of the resources necessary to produce the goods that an individual or population consumes. Finally, the lack of correlation between land degradation and the ecological footprint obscures the effects of a larger sustainability problem. What causes a high ecological footprint? Resource consumption such as […]
Which angle of light will heat the wood the most?
Which angle of light will heat the wood the most? 90° angle Why can you see objects placed under a heat lamp which emits infrared radiation? Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can […]
What is the electromagnetic spectrum used for?
What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
What is a secondary motion?
What is a secondary motion? Secondary animation also known as secondary motion, is used to refer to flat motions that are generated as a reaction to the movement of primary motion by a character. Examples of secondary motion include the rippling of water, swish of a cloak, or jiggle of body parts when a person […]
What are the 4 types of equilibrium?
What are the 4 types of equilibrium? There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of […]
What are examples of chemical hazards?
What are examples of chemical hazards? Some commonly used workplace chemical hazards include: Acids. Caustic substances. Cleaning products such as toilet cleaners, disinfectants, mildew remover and chlorine bleach. Glues. Heavy metals, including mercury, lead, cadmium, and aluminum. Paint. Pesticides. Petroleum products. How do you identify chemical hazards? To identify if a substance is hazardous, check […]
