What is the total electric flux through a closed surface containing a 2.0 μC charge?
A firm is considering to undertake one of these four projects. Recruit new staff. This would generate GH¢ 1,310 profit to the firm. Buy raw materials; which would generate GH¢ 1,420 profit. Pay workers’ bonuses. This would earn the firm GH¢ 1,500. Open another branch; which would make the firm record GH¢ 1,480 as profit. Each of the projects will cost the firm GH¢ 1,000.
(a) Rank the projects in order of importance, from the first to the last
(b) Find the opportunity cost of each project of the first three items in (a). (c) Find the net benefit of each of the first three items in (b) using
(i) direct cost.
(ii) opportunity cost.
(d) From your results in (cii), which project will you recommend to the firm? Explain your answer.
How to create c++ program using while loop that will get a number from the user. If the user inputs a number of more than 10, the program will be terminated, hence if lower than 10, the program will keep asking the user input number?
Make a program that will ask the student to enter a PIN Code. Each year level has its own PIN Code. If
the entered PIN Code is correct a message “Access Granted! Welcome yr_lvl Student.” will appear, if it is
wrong a message “Invalid PIN! Access Denied” will appear. The program will terminate after three (3)
incorrect attempt.
If 10.0 moles of O₂ are reacted with excess NO in the reaction below, and only 6.4 mol of NO₂ were collected, then what is the percent yield for the reaction?
2 NO (g) + O₂ (g) → 2 NO₂ (g)
What is group of individuals of one species living in isloation from similar group of individuals of this species and is characterized by higher levels of interbreeding
A particle of mass 3 Kg falls from rest at a point 5 m above the surface of a liquid which is in a container. There is no instantaneous change in speed of the particle as it enters the liquid. The depth of the liquid in the container is 4 m. The downward acceleration of the particle while it moving in the liquid is 5.5 m/s^2. (i) Find the resistance to motion of the particle while it is moving in the liquid. (ii) Sketch the velocity- time graph for the motion of the particle, from the time it starts to move until the time it reaches the bottom of the container. Show on your sketch the velocity and the time when the particle enters the liquid, and when the particle reaches the bottom of the container.
A car of mass 350 Kg is travelling at 30 m/s when it starts to slow down, 100 m from a junction. At first, it slows just using the air resistance of 200 N then, at a distance of s m from the junction, it slows using brakes, providing a force of 2000 N as well as the air resistance. Find the distance from the junction at which the brakes must be applied if the car is to stop at the junction.
The area between z = -2.40 and z = 1.15 is
An attorney’s office charge Php150 for every 20 minutes of consultation. Write a program that will ask
the user to enter the number of hours incurred for a consultation. The program then displays the bill of
the user and it starts over again. The loop will only stop if the user entered zero (0) hours for
consultation.
