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 […]
What can longitudinal waves not travel through?
What can longitudinal waves not travel through? Longitudinal waves are like mechanical waves which need the medium to propagate. These waves cannot travel through a vacuum. That is, there is absolutely in a vacuum. If there are no substances, then there are no particles for the sound waves to vibrate, which means the sound waves […]
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 […]
What is the most difficult form of abuse to identify?
What is the most difficult form of abuse to identify? Emotional abuse What happens if you ignore CPS? Q: Do parents have the right to refuse entry to an investigator? A: Yes. But refusing entry to CPS will not end the investigation. If CPS has information that a child may be in danger, they have […]
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 […]
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 […]
What are the effects of quenching?
What are the effects of quenching? Even cooling such alloys slowly in air has most of the desired effects of quenching; high-speed steel weakens much less from heat cycling due to high-speed cutting. Extremely rapid cooling can prevent the formation of all crystal structure, resulting in amorphous metal or “metallic glass”. What is the difference […]
What information does the slope of the line in a distance time graph give?
What information does the slope of the line in a distance time graph give? The slope of the distance-time graph indicates speed. It is because the slope of a distance-time graph determines the speed of that body, so the steeper the slope greater will be the speed of the body. What is the physical meaning […]
What is the angle of incident ray?
What is the angle of incident ray? In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The angle of incidence at which light is first totally internally reflected is known as the […]
