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 it mean when an object does not slip?
What does it mean when an object does not slip? It means the object moves uniformly in one direction along the surface, with no angular velocity about the object’s own center of mass. What does it mean when a ball rolls without slipping? Rolling without slipping is a combination of translation and rotation where the […]
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 are the 8 types of joints?
What are the 8 types of joints? Planar, hinge, pivot, condyloid, saddle, and ball-and-socket are all types of synovial joints. Is the wrist a gliding joint? Gliding joints occur between the surfaces of two flat bones that are held together by ligaments. Some of the bones in your wrists and ankles move by gliding against […]
Can WD 40 spontaneously combust?
Can WD 40 spontaneously combust? If the oil will cure and harden, then it is a fire hazard. WD40 won’t spontaneously combust. At what temperature does gasoline vapor ignite? 536°F. Is it safe to pressurize gasoline? 100 PSI isn’t exactly a small amount of pressure and in itself is rather dangerous. If the container bursts […]
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 […]
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 causes altocumulus?
What causes altocumulus? Altocumulus clouds usually form by convection in an unstable layer aloft, which may result from the gradual lifting of air in advance of a cold front. The presence of altocumulus clouds on a warm and humid summer morning is commonly followed by thunderstorms later in the day. What is the characteristic of […]
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 […]
Which condition causes storms to occur freezing of water droplets?
Which condition causes storms to occur freezing of water droplets? Cold Air Damming and Extended Lows Freezing rain develops when warm oceanic air rises up and over the cold air, producing liquid precipitation that falls through the cold layer. The falling droplets become supercooled and freeze on impact with the cold surface. Where is the […]
