Hello, I need help in a MCQ question. Thank you. Which one of these processes causes the neuron to return to the "resting potential" from the state of "action potential"? 1) Ion channels allow positively charged ions to flow out of the neuron. 2) Sodium-potassium pumps remove positively charged ions from the inside of the neurons until the "polarized state" is restored. 3) Enzymes dissolve the positively charged ions in the cells. 4) Negatively charged ions flow into the neuron...
To whom it may concern, Hello, I need help with this question: Question: "In a Joule experiment, a mass of 4.00 kg falls through a height of 50.0 m and rotates a paddle wheel that stirs 0.800 kg of water. The water is initially at 15 degrees C. By how much does its temperature rise (in degrees C)? " Let me know when you can. Thank you!
To whom it may concern, Hello, I need help with this question and seeing if I am doing the work and drawings correctly with units. Question: "Two electrons are 2.40 m. apart. Another electron is shot from infinity and comes to rest midway between the two. What must its initial velocity be (in meters/second)? " Let me know when you can. Thank you!
