Suppose the long solenoid in the figure a has 200 turns for every 50 cm of its length. The diameter of the solenoid is d=5 cm. Choose the correct statements (You may select more than one answer) for the flowing questions: 1- If the solenoid carries a constant current of $I$=10 A, calculate the magnetic field inside the solenoid (with direction) Fig. a a- Magnetic field inside the solenoid is zero because there are no magnets inside the solenoid b- Magnetic field inside the solenoid can't be determined since the total number of the turns and the total length of the solenoid are not given c- Magnetic field inside the solenoid is zero because the magnetic field form each loop canceled by the magnetic field from the next loop. d- Magnetic field inside the solenoid is zero because the current of the solenoid is constant (10 A) e- Magnetic field (in Tesla) inside the solenoid $B_s = \mu_0 n I (1)$ $n = \frac{200}{50} I = 10 A$. f- Magnetic field( (in Tesla) inside the solenoid $B_s = \mu_0 n I (-1)$ $n = \frac{200}{0.50} I = 10 A$. g- Magnetic field (in Tesla) inside the solenoid $B_s = \mu_0 n I (1)$ $n = \frac{200}{50} I = 10 A$. h- Magnetic field (in Tesla) inside the solenoid $B_s = \mu_0 n I (-1)$ $n = \frac{200}{50} I = 10 A$. 2- A conducting 20 turns circular coil with radius $r = 2$ cm placed inside the solenoid such that the axis of the coil coincides with the axis of the solenoid (the surface of the coil is normal to the axis of the solenoid as shown in figure b).

Suppose that $80,000 is invested at 7% interest. Find the amount of money in the account after 10 years if the interest is compounded annually. If interest is compounded annually, what is the amount of money after t= 10 years? $ (Do not round until the final answer. Then round to the nearest cent as needed.)

increased -- a big rightward shift -- what was the initial impact on the market? Hannah Good question! I have a graph and some data to help us talk this through. Derrick Ah, very helpful! So when the demand curve shifted right and the market price was still $10 for the masks, what was the new quantity demanded of masks? In other words, how many masks did people want to buy for $10 after the outbreak?

None of the questions posted prior are corrected and I don't understand how to solve this. Please help! Part A: Mechanisms of how it is maintained differ from those of mammalian cells. The transport of protons across the cell membrane is an important part of the mechanism, so a bacterium's membrane potential varies with the proton concentration - the pH - of the surrounding fluid. One strain of bacteria was found to have a membrane potential of -120V at a pH of 7.5. A bacterium can be modeled as a 1.5 nm diameter sphere. How many positive ions are needed on the exterior surface to establish this membrane potential? (There are an equal number of negative ions on the interior surface.) Assume that the membrane is ions. Submit Previous Answers Best Answer: Incorrect. Try Again. 4 attempts remaining.
