here are the solutions to the questions:

5. (a) A student wrote the following program code to make a robot walk 10 steps:

repeat (2)
  move (5) steps
end

What is the correct programming term for the code structure?

The code structure shown is a type of loop. It instructs the program to repeat a set of actions a specified number of times.

The correct programming term for the code structure is loop or iteration.

5. (b) A girl is writing a computer program to calculate the total expenses for her birthday party. A bag costs Gh¢200.00. She needs one for each of her 12 friends. She also bought a special cake for Gh¢150.00. She further bought a cap for Gh¢23.00 for each of her 7 best friends.
She wrote her expenses in the computer program as:

Total\_Expenses = 12 \times Gh¢200.00 + Gh¢150.00 + 7 \times Gh¢23

Calculate the Total Expenses for the girl's birthday party using the computer operator precedence.

Perform the multiplications first, according to operator precedence.
$12 \times Gh¢200.00 = Gh¢2400.00$ $7 \times Gh¢23 = Gh¢161.00$
Substitute these values back into the expression.
$Total\_Expenses = Gh¢2400.00 + Gh¢150.00 + Gh¢161.00$
Perform the additions.
$Total\_Expenses = Gh¢2550.00 + Gh¢161.00$ $Total\_Expenses = Gh¢2711.00$
- The total expenses for the girl's birthday party are $\boxed{\text{Gh¢2711.00}}$ .
5. (c) A robotic arm in a factory is strong enough to lift a heavy metal box. However, when it tries to pick up a delicate light bulb, it crushes it.
List two main components that need to be improved or added to help the robotic arm handle both heavy and delicate objects safely.

To handle both heavy and delicate objects, a robotic arm needs to be able to sense the force it is applying and adjust its grip accordingly.
- (i) Force/Pressure Sensors: These sensors, typically integrated into the gripper or fingertips, would detect the amount of pressure being exerted on an object. This allows the robot to "feel" how hard it is gripping.
- (ii) Feedback Control System / Adjustable Gripper Mechanism: A sophisticated control system that uses data from the force sensors to dynamically adjust the gripping force. Alternatively, the gripper itself could be improved with an adjustable mechanism or compliant materials that allow for a gentler, more adaptive grip.

Step-by-step solution

Perform the multiplications first, according to operator precedence.

Substitute these values back into the expression.

Perform the additions.
