What are the 3 laws of force? In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other […]
What happens when the temperature of moist air decreases?
What happens when the temperature of moist air decreases? Ratio of the amount of water vapor in the air to the amount of water vapor needed to reach saturation. What happens when the temperature of air decreases to the dew point? it creates cool clear nights with little wind. In cooler temperatures the water molecules […]
Why does normal wire fail at microwave?
Why does normal wire fail at microwave? Conventional wires can not carry microwaves because of the energy they give off; instead, coaxial cables can carry microwaves up to 5 GHz in frequency because their self-shielding conductors prevent radiating energy. Is the transmission of data by microwave radio waves? Microwave is a line-of-sight wireless communication technology […]
Is there a number I can text to talk about my problems?
Is there a number I can text to talk about my problems? Crisis Text Line is the first 24/7, text-based helpline of its kind, and most importantly, it isn’t specific — unlike most other helplines, users going through any kind of crisis are free to call. To volunteer with the Crisis Text Line, check out […]
What is the change in internal energy for a system that does 70j?
What is the change in internal energy for a system that does 70j? Answer. According to First Law of Thermodynamics, ⇒ Internal energy (ΔU)= q+W = (-45)+70 = -25 J. What is the change in internal energy U for a system? One way we can increase the internal energy U (and therefore the temperature) of […]
How can we identify a particular element?
How can we identify a particular element? Explanation: There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in […]
How much does a 8 foot 2×2 weigh?
How many days are in a month without weekends?
What are the three factors that contribute to the resting membrane potential?
What are the three factors that contribute to the resting membrane potential? Membrane potentials in cells are determined primarily by three factors: 1) the concentration of ions on the inside and outside of the cell; 2) the permeability of the cell membrane to those ions (i.e., ion conductance) through specific ion channels; and 3) by […]
Can copper become an electromagnet?
Can copper become an electromagnet? An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Does copper contain electricity? Copper has the best electrical conductivity of any metal, except silver. A good […]
