An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
In 30 seconds, an electric device with a current of 15.0 A delivers approximately 2.81 sextillion electrons. This is calculated by first finding the total charge using the formula Q = I × t, then dividing by the charge of a single electron. The final result shows that about 2.81 × 10^21 electrons flow through the device.

To answer the student's question about the manufacturing costs of stainless steel flatware by GOLDMINE Inc., we need to categorize the costs into direct material costs, direct labor costs, and total overhead costs for the year 2026.
(a) Direct Material Cost for 2026:
Direct materials are those raw materials that are used directly in the manufacturing of products. For GOLDMINE Inc., the direct material costs include:
Stainless steel: P 444 , 500
Plastic and fiberglass for handles: P 22 , 500
The equipment oil and grease are typically considered indirect materials, as they help in the production process but do not become part of the final product.
Therefore, the total direct material cost is: P 444 , 500 + P 22 , 500 = P 467 , 000
(b) Direct Labor Cost for 2026:
Direct labor costs refer to the wages of employees who are directly involved in the production of goods. For flatware production, direct labor includes:
Equipment operators: P 200 , 000
The equipment mechanics and factory supervisors are generally not considered direct labor, as they might oversee or maintain the production but are not directly involved in producing the product itself.
Thus, the direct labor cost is: P 200 , 000
(c) Total Overhead Cost for 2026:
Manufacturing overhead includes all costs associated with the manufacturing process that are not direct material or direct labor costs. For GOLDMINE Inc., overhead costs include:
Equipment oil and grease: P 12 , 000
Equipment mechanics: P 50 , 000
Factory supervisors: P 118 , 000
So, the total overhead cost is: P 12 , 000 + P 50 , 000 + P 118 , 000 = P 180 , 000
In summary, for 2026:
The direct material cost is P 467 , 000 .
The direct labor cost is P 200 , 000 .
The total overhead cost is P 180 , 000 .
