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 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 […]
Why is current constant in a parallel circuit?
Why is current constant in a parallel circuit? Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit). Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total […]
What are two different types of electron microscopes?
What are two different types of electron microscopes? There are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image. What is the greatest advantage of […]
What is the difference between positive reinforcement and positive punishment?
What is the difference between positive reinforcement and positive punishment? Instead, positive means you are adding something, and negative means you are taking something away. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. All reinforcers (positive or negative) increase the likelihood of a behavioral response. How do you […]
What does the phrase one on a side mean?
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 […]
Is La Nina related to climate change?
Is La Nina related to climate change? In a warming climate, rainfall extremes are projected to shift eastward along the equator in the Pacific Ocean during El Niño events and westward during extreme La Niña events. Will 2020 be the hottest year on record? Globally, 2020 was the hottest year on record, effectively tying 2016, […]
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 […]
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 […]
