Charge is moving through a wire. An amount of charge $Q$ moves past a particular spot in the wire in an amount of time $t$ to produce a current of $I$. What happens to the magnitude of the current when it takes four times as long for the same amount of charge to be moved past that point in the wire at a steady rate? new current $I_{new}$ is $\frac{I_{old}}{4}$ new current $I_{new}$ is $16I_{old}$ new current $I_{new}$ is $\frac{I_{old}}{16}$ new current $I_{new}$ is $4I_{old}$ What happens to the magnitude of the current when the amount of time to move the charge does not change, but the amount of charge moved past that point in the wire at a steady rate is four times as much? new current $I_{new}$ is $\frac{I_{old}}{4}$ new current $I_{new}$ is $16I_{old}$ new current $I_{new}$ is $\frac{I_{old}}{16}$ new current $I_{new}$ is $4I_{old}$

#3 A tennis player hits a ball 1.6 m above the ground. The ball leaves the racket with a speed of 12 m/s at an angle 8.0° above the horizontal. The net is a horizontal distance of 7.0m away from the player and is 1.0 m high. (a.) Does the ball clear the net? Explain how you determined this. You must do a correct numerical calculation as part of your explanation. (b.) If the ball clears the top of the net, by what vertical distance does it clear it? If not, by what vertical distance does it miss?

Stock in Company A sells for $86 a share and has a 3-year average annual return of $22 a share. The beta value is 1.03. Stock in Company B sells for $85 a share and has a 3-year average annual return of $17 a share. The beta value is 1.21. Derek wants to spend no more than $18,000 investing in these two stocks, but he wants to earn at least $2900 in annual revenue. Derek also wants to minimize the risk. Determine the number of shares of each stock that Derek should buy. Set up the linear programming problem. Let a represent the number of shares of stock in Company A, b represent the number of shares of stock in Company B, and z represent the total beta value subject to $86a + 85b$ $22a + 17b$ $a \ge 0, b \ge 0$ (Use integers or decimals for any numbers in the expressions. Do not include the $ symbol in your answers.)
