What is the charge for nitrogen 15? +1 Why is nitrogen-14 not an isotope? What do all isotopes of an element have in common? Explain why carbon-14 and nitrogen-14 are not considered isotopes of each other? Because they are two different elements. Same mass number but different atomic number. What does the 14 mean in […]
What would happen if we stop deforestation?
What would happen if we stop deforestation? We would be saving this much because of how much deforestation costs when compared to how much it makes. However, it would also cause people to lose their jobs, and it would require us to come up with an alternative to paper, pulp, and paperboard. How does deforestation […]
What is resultant force example?
What is resultant force example? Translation: When a system of forces is acting on an object, the difference between the forces is called the Resultant force. For example, a 3N force to the left and 10N force to the right gives a resultant force of 7N to the right. How do you solve resultant force […]
Which is the best description of the proprioception?
Which is the best description of the proprioception? Proprioception, also called kinesthesia, is the body’s ability to sense its location, movements, and actions. It’s the reason we’re able to move freely without consciously thinking about our environment. WHO emphasized that in order for a person to detect a difference between two stimuli? Ernst Weber proposed […]
What is a property of most metals electrons?
What is the purpose of scientific model?
What is the purpose of scientific model? Scientific models are used to explain and predict the behaviour of real objects or systems and are used in a variety of scientific disciplines, ranging from physics and chemistry to ecology and the Earth sciences. How do you describe a scientific model? A scientific model is a physical […]
Does water cause erosion?
Does water cause erosion? Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. What are the 3 types […]
Why are specific properties intensive?
Why are specific properties intensive? Intensive properties are properties that do not depend on the quantity of matter. For example, pressure and temperature are intensive properties. Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system. What are the extensive properties of matter? All properties of matter are […]
How is a sperm cell Specialised?
How is a sperm cell Specialised? Sperm Cells are specialised in a number of ways. They have an Undulipodium (tail) which moves by energy generated by many mitochondria and propels the cell. The head of the cell contains an Acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate […]
Can intelligence be sent without a carrier?
Can intelligence be sent without a carrier? The intelligence signal is generally a low frequency signal. So, it cannot be transmitted for a long distance by using antenna due to low frequency. But it can be transmitted directly by using wires. Why is carrier frequency higher than message frequency? To increase the energy of the […]
