Which real world scenarios represent physical changes? Answer Expert Verified. Answer is: mixing water and powdered drink mix, combining oil and vinegar to make salad dressing, diluting bleach with water and dinner spreading peanut butter on bread. Physical property can be observed and measured without any changes in molecular composition. Which of these is an […]
What is limitation of model?
What is limitation of model? Models are used to simulate reality and make predictions. The major limitation of models is that they are ‘idealizations’ or ‘simplification’ of reality and thus cannot possibly replace reality. A number of assumptions are made during modeling and this causes differences between model and reality. What are some model limitations? […]
Which gas has highest global warming potential?
Which gas has highest global warming potential? Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO2. Which gas has least global warming potential? Use in Kyoto Protocol and UNFCCC Greenhouse gas Chemical formula […]
What is true for living organism?
What is true for living organism? All living things are made of cells, use energy, respond to stimuli, grow and reproduce, and maintain homeostasis. All living things consist of one or more cells. All life processes require energy, so all living things need energy. All living things can sense and respond to stimuli in their […]
How does a human presence sensor work?
How does a human presence sensor work? Sensors Powering Human Presence Detection Ambient light sensors: As the name suggests, these sensors detect light in the environment. They can measure the light reflecting from an approaching user to detect human presence from a distance. How does a presence sensor work? Presence sensors/motion sensors actually detect the […]
What is the Hydra in real life?
What is the Hydra in real life? It is suggestively based on the British Aerospace Harrier II (formerly known as the Hawker Siddley Harrier) a well-known British fighter jet with Vertical Takeoff and Landing (VTOL) capabilities, with minor detailing from the F-16 Fighting Falcon, such as the cockpit and air intake. Is the Hydra faster […]

What is the longest thunderstorm recorded?
What is the longest thunderstorm recorded? A new world record lightning strike of 440 miles has been confirmed by the World Meteorological Organization, according to a Thursday announcement. The “megaflash” traveled that distance over parts of southern Brazil on Oct. 31, 2018, the WMO said. This is equivalent to the distance between Washington, DC, and […]
