A point charge with a mass of 1.81 ng and a charge of +1.22 uC moves in the x-y plane with a velocity of 3.00 x 104 m/s in a direction 15° above the +x-axis. At time t=0, the point charge enters a uniform magnetic field of strength 1.25 T that points in the +x-direction. Assume that the point charge remains immersed in the uniform magnetic field after time t=0.
a. (5 points) What is the magnitude and direction of the magnetic force that the magnetic field exerts on the point charge at time t=0?
b. (5 points) How does the x-component of the charge’s initial velocity effect the motion of this point charge as it moves through the uniform magnetic field? Does its magnitude change? Does its direction change? Explain your reasoning.
c. (5 points) How does the y-component of the charge’s initial velocity effect the motion of this point charge as it moves through the uniform magnetic field? Does its magnitude change? Does its direction change? Explain your reasoning.
d. (5 points) Use your answers from parts 1b & 1c to explain why the path of this point charge is helical (corkscrew-shaped). Explain your reasoning.
e. (2.5 points) Determine the radius of the circular part of the point charge’s helical path.

Consider an economy with three people and two goods, one public (g) and one private (x). The utility functions for the three people are UA = xA +20lng, UB = xB +30lng, and UC = xC +10lng. The marginal cost of g is constant at 10. According to the Samuelson condition, what is the socially efficient amount of the public good in this economy? Explain why the Samuelson condition picks out the efficient amount of a public good.

Note: Creating multiple Scanner objects for the same input stream yields unexpected behavior. Thus, good practice is to use a single Scanner object for reading input from System.in. That Scanner object can be passed as an argument to any methods that read input.
(1) Create an ItemToPurchase class per the following specifications:
Ex. of printItemCost() output:
Bottled Water 10 @ $1 = $10
Ex. of printItemDescription() output:
Bottled Water: Deer Park, 12 oz.
(2) Create two new files:
Build the ShoppingCart class with the following specifications. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.
Private fields
String customerName - Initialized in default constructor to "none"
String currentDate - Initialized in default constructor to "January 1, 2016"
ArrayList cartItems
Default constructor
Parameterized constructor which takes the customer name and date as parameters
Public member methods
getCustomerName() accessor
getDate() accessor
Ex. of printTotal() output:
John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521
Ex. of printDescriptions() output:
John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones
(3) In main(), prompt the user for a customer's name and today's
date. Output the name and date. Create an object of type
ShoppingCart.
Ex.
Enter Customer's Name: John Doe Enter Today's Date: February 1, 2016 Customer Name: John Doe Today's Date: February 1, 2016
(4) Implement the printMenu() method. printMenu() has a ShoppingCart parameter, and outputs a menu of options to manipulate the shopping cart. Each option is represented by a single character. Build and output the menu within the method.
If the an invalid character is entered, continue to prompt for a
valid choice. Hint: Implement Quit before implementing other
options. Call printMenu() in the main() method. Continue to
execute the menu until the user enters q to Quit.
Ex:
MENU a - Add item to cart d - Remove item from cart c - Change item quantity i - Output items' descriptions o - Output shopping cart q - Quit Choose an option:
(5) Implement Output shopping cart menu option.
Ex:
OUTPUT SHOPPING CART John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521
(6) Implement Output item's description menu option.
Ex.
OUTPUT ITEMS' DESCRIPTIONS John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones
(7) Implement Add item to cart menu option.
Ex:
ADD ITEM TO CART Enter the item name: Nike Romaleos Enter the item description: Volt color, Weightlifting shoes Enter the item price: 189 Enter the item quantity: 2
(8) Implement Remove item menu option.
Ex:
REMOVE ITEM FROM CART Enter name of item to remove: Chocolate Chips
(9) Implement Change item quantity menu option. Hint: Make
new ItemToPurchase object and use ItemToPurchase modifiers before
using modifyItem() method.
Ex:
CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: 3

Using a wheatstone bridge, solve for Vout for quarter, half, and full bridges and determine which one is most sensitive. Draw a diagram showing how you would place your strain gauges on a beam for each configuration. Discuss how you should use the right kind of strain gauge with appropriate G values to maximize the sensitivity.
