Is a fish wet underwater? Yes, a fish (when in water) is wet. They have a protective slime layer all over themselves that protects them from getting waterlogged, so they never appear prune-like or shriveled. But the water is on the outside of that slime layer, so yes, they are wet. Originally Answered: Is a […]
How do you calculate the power of a hydraulic pump?
What are the two types of mantle?
What are the two types of mantle? Earth’s mantle Earth’s mantle is a layer of silicate rock between the crust and the outer core. Earth’s mantle is divided into two major rheological layers: the rigid lithosphere comprising the uppermost mantle, and the more viscous asthenosphere, separated by the lithosphere-asthenosphere boundary. How do you get rid […]
Is freezing water a chemical property?
Is freezing water a chemical property? Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes. On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed. The chemical change also usually involves heat, burning, or other interaction with […]
What are three common types of evidence for a chemical change?
What are three common types of evidence for a chemical change? Evidence of a chemical change Change of odor. Change of color (for example, silver to reddish-brown when iron rusts). Change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat. Change of composition – paper turning to ash when burned. […]
Can acceleration decrease while speed increases?
Can acceleration decrease while speed increases? Also to know is, why does acceleration decrease as speed increases? An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. Because the velocity is a vector, you have to consider the changes to its […]
Can something be both a physical and chemical change?
Can something be both a physical and chemical change? Melting and burning of candle wax is an example of both physical and chemical changes. Answer: Burning of wood is a example of both physical and chemical change. When wood is burnt the moisture present in it turns to vapour ,it is a physical change while […]
What are the use of plates?
What are the use of plates? A plate is a broad, concave, but mainly flat vessel on which food can be served. A plate can also be used for ceremonial or decorative purposes. Most plates are circular, but they may be any shape, or made of any water-resistant material. What is another word for plate? […]
What is the potential energy of a stretched wire?
What is the potential energy of a stretched wire? According to Hooke’s law, the force applied to stretch the spring is directly proportional to the amount of stretch. Where, P.E = elastic potential energy and it’s expressed in Joule….The video explains how a stretched rod is analogous to a stretched spring. FORMULAS Related Links A […]
What can we learn from the deep ocean?
What can we learn from the deep ocean? Information from ocean exploration can help us understand how we are affecting and being affected by changes in Earth’s environment, including changes in weather and climate. Insights from ocean exploration can help us better understand and respond to earthquakes, tsunamis, and other hazards. How do oceans benefit […]
