Will cats come down from trees on their own? Cats’ claws are shaped like fish hooks, and trees are nature’s escape routes for them. They will often climb until they feel safe, then stop and realize they’re stuck. The only safe way for them to get down unaided is to go down backward, which, unsurprisingly, […]
What is the correct formula for calculating COP of heat pump?
What is the correct formula for calculating COP of heat pump? Answer. Explanation: COPHP = (Desired Output)/(Required Input) = (Heating Effect)/(Work Input) = QH/Wnet,in = 1 + (QL/Wnet,in) Both the COP of a refrigerator and a heat pump can be greater than one. Can COPs be less than1? The coefficient of performance (COP) of refrigeration […]

Is an object position at a particular instant?
Is an object position at a particular instant? Position. The position of an object is its location relative to a well-defined coordinate system at a particular instant of time. Without a specified coordinate system, position is a meaningless concept. A coordinate system is comprised of a zero, a specified positive direction, and a scale. What […]
What is resonance frequency of LC circuit?
What is resonance frequency of LC circuit? Resonance occurs when an LC circuit is driven from an external source at an angular frequency ω0 at which the inductive and capacitive reactances are equal in magnitude. The frequency at which this equality holds for the particular circuit is called the resonant frequency. How does an LC […]
Why does aluminum foil block WiFi signals?
Why does aluminum foil block WiFi signals? If you’ve ever thought of resorting to aluminum foil to redirect your home’s poor WiFi signal, it turns out you’re not actually that far off the mark. The foil, an electrical conductor, creates a barrier called a Faraday Cage around the phone, blocking the radio signals on which […]
What is the specific volume of water?
What is the specific volume of water? The specific volume that correlates to that density is 0.00094 m3/kg. Notice that the average specific volume of blood is almost identical to that of water: 0.00100 m3/kg. What happens to volume when height is doubled? Step-by-step explanation: So, if R = constant, the volume changes in direct […]
