Which observations correctly describe the second law of thermodynamics? Check all that apply. Thermal energy that is not used to do work is often released to the surroundings. Thermal energy flows from a cooler object to a warmer object. Thermal energy flows from a warmer object to a cooler object. Thermal energy is released as unusable energy by a heat engine, which is never 100 percent efficient. Thermal energy flows when two objects in contact have a temperature difference.

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
