Use curved arrows to draw the movement of electrons during this reaction. Helpful hint: Look for bonds broken. Where did those electrons go? Look for new bonds formed. Where did the electrons In the bond come from? Lone pairs can become bond pairs and bond pairs can become lone pairs. CH$_{3}$-CH$_{2}$-Ö:- + CH$_{3}$-Cl̈: $\longrightarrow$ CH$_{3}$-CH$_{2}$-Ö-CH$_{3}$ :Cl̈:-

Which part of a neuron picks up signals at receptor sites and send them toward the cell body?
In this section, Strang discusses conditions for an autonomous differential equation, $y' = f(y)$, to have a stable steady state at y = Y (see pages 58-59). Given below is an autonomous first order differential equation, Which of the following are true? $y' = y^3 + y^2 - 9y - 9$ I. $y = -1$ is a stable fixed point. II. $y = -3$ is a stable fixed point. III. $y = -1$ is an unstable fixed point. IV. $y = -3$ is an unstable fixed point.
Question 3: Monetary Policy and Open Market Operations Suppose that money demand is given by: M = $Y(0.25 - i) where $Y is $100. Also, suppose the supply of money is $20. a. What is the equilibrium interest rate? b. Say the Federal Reserve wants to increase i by 10 percentage points. i. What does this policy choice imply about how well the economy is doing? ii. Does it need to buy or sell bonds? Why? c. If the Federal Reserve wants to increase i by 10 percentage points, at what level should it set the money supply? d. Show graphically how a change in the money supply leads to an increase in the interest rate.
When an insulator is placed in an external uniform electric field, A. the net electric field within the insulator is greater than the external electric field. B. the induced electric field within the insulator is perpendicular to the external field. C. electric dipoles are induced within the insulator and produce induced electric field opposite to the external field. D. the electric field induced within the insulator is greater than the external electric field, but has the same direction as the external field.
2. You're moving the crate (m=100kg) across a rough floor by pushing on it at an angle of 30° above the horizontal. The acceleration of the cart is 1 m/s². If $\mu_k$=0.3, what is the magnitude of the force you're applying to the crate? Present free-body diagram. 3. For a situation as in problem 2, calculate work done by you, work done by friction and net work done if crate was moved 2m.
