Question Solved1 Answer Given an array of non-negative integers [2,3,1,4,2,3], you are initially positioned at the first index of the array. Each element in the array represents your maximum jump length at that position. What is minimum number of jumps to the last index of the array. a. 7 b. 2 c. 6 d. 5

Write a program to create an Address Book in Java. The Address Book accepts a Person's Name, Address, and Phone number. Use a text based menu-driven approach. A user may create a new entry in their address book and input a name, address, and phone number. A user may list all the members of their address book. 1. Add a new contact 2. Update an existing contact 3. Delete a contact 4. List all added contacts in sorted order 5. Search for a given contact. Search can be done by first name, last name, or phone number. Return all the details upon finding a match. 6. Quit Persist the contacts in the AddressBook. Save to the file and load from the file when the program executes.

Plot a, (Stewart 9.3 30 and 34, modified) Let a = (1, 2) and b = (-4,1). (a) Find the vector projection of b onto a, denoted projab and find its length (called the scalar projection). b and projab in the plane. (b) The orthogonal projection of b onto a, denoted orthab is the vector b - projab. Find orthab and plot it in the plane. Why do you think we call orthab the orthogonal projection of b onto a? What vector(s) is it perpendicular to in the example you sketched? (c) Show for any non-zero vectors a and b that orthab is perpendicular to a.

(a) Use the definition given below with right endpoints to express the area under the curve y = x3 from 0 to 1 as a limit. = The area A of the region S that is bounded above by the graph of a continuous function y = f(x), below by the x-axis, and on the sides by the lines x = a and x = b is the limit of the sum of the areas of approximating rectangles. n lim Rn A = n00 lim [f(x4)Ax + f(x2)4x + = + f(x,)Ax] = lim. į f(x;)Ax n00 i=1 n lim n00 i = 1 (b) Use the following formula for the sum of cubes of the first n integers to evaluate the limit in part (a). 12 13 + 23 + 33 + ..-( ) 3 = n(n + 1) 2

A planet of mass 3 x 1024 kg is at location (5 x 1011, -5 x 1011, 0) m. A star of mass 3 x 1030 kg is at location (-5 x 1011, 4 x 1011, 0) m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position vector r pointing from the planet to the star? r= m (b) What is the distance between the planet and the star? Irl m (c) What is the unit vector in the direction of r? (d) What is the magnitude of the force exerted on the planet by the star? |Fon planet| = N (e) What is the magnitude of the force exerted on the star by the planet? |Fon star] = N (f) What is the force (vector) exerted on the planet by the star? (Note the change in units.) Fon planet = x 1020 N (g) What is the force (vector) exerted on the star by the planet? (Note the change in units.) Fon star = x 1020 N

JAVA write 2 classes : CashRegister.java and CashRegisterTester.java a cashRegister should have 3 instance variables:- itemCount that represents the numbers of items bought, totalPrice that represents the total price of all your items, and itemNames that represents a concatenated string of the names of all the products you bought. The CashRegister should

Consider the following reaction: A + 2B → E Using steady-state approximation determine which of the following can determine the overall rate law (assume that the rate determining step is unknown), if the reaction mechanism consists of the following elementary steps: 1. A + B → 2C (rate constants: k1 for forward reaction; k2 for reverse reaction) 2. 2C + B → E (rate constant: k3) Question 4 options: a) k3[B][C]2 b) (k3k1[A]2[B])/(k2+k3[A]) c) (k3k1[A][B]2)/(k3-k2[B]) d) (k3k1[A][B]2)/(k2+k3[B]) e) (k3k1[A][B]2)/(k3+k2[B])
