THIS IS THE PROGRAM CODE:

#include <stdio.h>

void main (void)

{

int intval = 255958283;

void *vptr = &intval;

printf ("The value at vptr as an int is %d\n", *((int *) vptr));

In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 52.0 km due north. A detector is placed 107 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.

(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

(b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.005

provide 5 ways/methods and explain them on how global warming can be reduced in the future?

Research consistently shows that living in poverty negatively influences language development. Locate and summarize information that would support this assumption (e.g., journal articles, Centers for Disease Control [CDC], and/or World Health Organization [WHO]). What types of experiences or resources do you feel that children who live in poverty do not experience or receive but children from higher economic statuses benefit from?

draw vsepr and valence bond picture for C2H2? label the bonds. for each sigma bond name the two orbitals that overlap to form it? for each pi bond name the two orbitals that overlap to form it. why are to pi ponds perpindicular to each other. why are quadruple bonds unlikely? Please label thank you.

In the earth's reference frame, a tree is at the origin and a pole is at x=31km. Lightning strikes both the tree and the pole at t=13?s. The lightning strikes are observed by a rocket traveling in the x-direction at 0.6 c.

What are the spacetime coordinates x? tree, x? pole for these two events in the rocket's reference frame?

What are the spacetime coordinates t? tree, t? pole for these two events in the rocket's reference frame?

Square Manufacturing is considering investing in a robotics manufacturing line. Installation of the line will cost an estimated $10.5 million. This amount must be paid immediately even though construction will take three years to complete (years 0, 1, and 2). Year 3 will be spent testing the production line and, hence, it will not yield any positive cash flows. If the operation is very successful, the company can expect after-tax cash savings of $7.5 million per year in each of years 4 through 7. After reviewing the use of these systems with the management of other companies, Square’s controller has concluded that the operation will most probably result in annual savings of $4.9 million per year for each of years 4 through 7. However, it is entirely possible that the savings could be as low as $3.3 million per year for each of years 4 through 7. The company uses a 14 percent discount rate. Use Exhibit A.8.

Required:

Compute the NPV under the three scenarios. (Round PV factor to 3 decimal places. Enter your answers in thousands of dollars. Negative amounts should be indicated by a minus sign.)

Hank, a calendar-year taxpayer, uses the cash method of accounting for his sole proprietorship. In late December, he performed $28,000 of legal services for a client. Hank typically requires his clients to pay his bills immediately upon receipt. Assume his marginal tax rate is 32 percent this year and will be 35 percent next year, and that he can earn an after-tax rate of return of 12 percent on his investments. Use Exhibit 3.1.

a. What is the after-tax income if Hank sends his client the bill in December?

b. What is the after-tax income if Hank sends his client the bill in January? (Do not round intermediate calculations. Round your answer to the nearest whole dollar amount.)

Compare the total surplus TS in a market with no trade at P_dom to a market with imports eP_imp < P_dom and another market with exports eP_exp > P_dom. Explain which groups win and which lose in the import and export markets compared to the autarky market.

A 0.4627 g sample of pewter, containing tin, lead, copper, and zinc, was dissolved in acid. Tin was precipitated as SnO2·4H2O and removed by filtration. The resulting filtrate and washings were diluted to a total volume of 200.0 mL. A 20.00 mL aliquot of this solution was buffered, and titration of the lead, copper, and zinc in solution required 34.11 mL of 0.001500 M EDTA. Thiosulfate was used to mask the copper in a second 25.00 mL aliquot. Titration of the lead and zinc in this aliquot required 34.45 mL of the EDTA solution. Finally, cyanide was used to mask the copper and the zinc in a third 30.00 mL aliquot. Titration of the lead in this aliquot required 24.39 mL of the EDTA solution. Determine the percent composition by mass of each metal in the pewter sample.

Simone works for a group that wants to register more people to vote. She knows her team can only ask a
certain number of people at any given time since they have other obligations. She has asked you to create a
program for her team that allows the user to type in how many people they want to ask at one time (the
duration of the current program run). The program will then ask that many people (see sample run). If a
person answers y, his or her name is added to a registration list (a file) and the current registration list is
output to screen. If they answer n, Ok is output to screen and the program continues. Once at least 10 people
have been registered, whenever the program is opened the phrase Target Reached! Exiting… should be
output to screen.
Step 1: You will be defining the following two functions (DO NOT MODIFY THE DECLARATIONS):
/*This function takes a file pointer, goes through the file and prints the file contents to screen. It returns the
number of lines in the file*/
int registered(FILE *fp)
/*This function takes a file pointer and adds a new line to the file*/
void new_register(FILE *fp)
Step 2: Use the functions you defined to make a working program.
Sample Run:
computer$ gcc –o vote vote.c
computer$ ./vote register.txt
