Develop a Java program for a car dealership shop that allows the dealer to enter the buying price of 5 cars and their models. the program then computes and displays the selling price and profit of each car the rate for selling price is 240% of buying price. Selling price = buying price * rate , profit = selling price - buying price .
Design a project to determine the specifications (unstretched length) spring constant k as 100N/m for the elastic cord to be used at a bungee-jumping facility. Participants are to jump from a platform 45m above the ground. When they rebound, they must avoid an obstacle that extends 5 m below the point at which they jump. In determining the specifications for the cord, establish reasonable the safety limits for the minimum distances by which participants must avoid the ground and obstacle. Account for the fact that participants will have different weight. (Specify a maximum allowable weight for participants of 100kg, and Maximum height of 1.7m)
4)Mr Caleb the Hoc of 200 level computer science in Caleb university bought the following goods in one of the warehouse in Lagos where prices of these goods or products are displayed exclusive
*One bag of rice @ 30,000.00 naira
*A 25 litre of groundnut oil @15,000 naira each
*50kg of beef @5,000 naira each
a)Write a C++ program to find the total amount paid by Caleb HOC if VAT was charged @17.5%
b)What is the total Expenditure of HOC is transportation
A batch of concrete is made using the following materials *cement=30,000kg *Sand=50,000kg *Gravel=17,500kg *Water=3000kg a)Write a C++ program code to calculate and display the amount of sand in a real number and a percentage of the total mass of concrete. b)The amount of water in real number,and a percentage of the amount of cement.
Two circular loops A and B have their planes parallel to each other. Loop A has a current moving in the counterclockwise direction when viewed from above.
a. If the current in loop A decreases with time, what is the direction of the current in loop B? will the two loops attract or repel each other?
b. If the current in Loop A increases with time, what will be the direction of the current in Loop B? Will the two loops attract or repel each other?
An insulating sphere of radius 8.0 cm carries a uniform volume charge density
of 500 nC/m^3. What is the electric field in N/C at r = 3.0 cm?
Solve the exact differential equation = ( x - 2ey ) dy + y + ( xsin(x) ) dx = 0
Solve the differential equation = x dy / dx + 2y = x4
( x - 2ey ) dy + y + ( xsin(x) ) dx=0
Two circular loops A and B have their planes parallel to each other.
Loop A has a current moving in the counter clockwise direction, viewed from above.
1. If the current in loop A decreases with time, what is the direction of the induced current in loop B? Will the two loops attract or repel each other?
2. If the current in loop A increases with time, What is the direction of the induced current in loop B? Will the two loops attract or repel each other?
