An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Classify 'queso' as dairy.
Classify 'pescado' as protein.
Classify 'manzana' as fruit.
Classify 'zanahoria' as vegetable.
Classify 'dulces' as sweets.
Classify 'pollo' as protein.
Classify 'naranja' as fruit.
Classify 'pan' as grain.
Classify 'brócoli' as vegetable.
Classify 'leche' as dairy.
The food groups are identified for each food item in the table: Dairy, Protein, Fruit, Vegetable, Sweets, Protein, Fruit, Grain, Vegetable, Dairy
Explanation
Identifying Food Groups We need to classify each food item into its corresponding food group. The main food groups are dairy, protein, fruit, vegetable, sweets, and grains.
Classifying Each Food Item
Queso (Cheese): Dairy
Pescado (Fish): Protein
Manzana (Apple): Fruit
Zanahoria (Carrot): Vegetable
Dulces (Sweets): Sweets
Pollo (Chicken): Protein
Naranja (Orange): Fruit
Pan (Bread): Grain
Brócoli (Broccoli): Vegetable
Leche (Milk): Dairy
Examples
Understanding food groups is essential for planning a balanced diet. For example, if you're planning a meal, knowing that chicken is a protein source helps you pair it with vegetables and grains to create a complete and nutritious meal. Similarly, recognizing fruits and vegetables allows you to ensure you're getting enough vitamins and minerals in your daily intake. This knowledge is also crucial in making informed decisions when grocery shopping or eating out, enabling you to choose healthier options.
To find the number of electrons flowing through the device, we first calculate the total charge using the formula Q = I × t , which results in 450 coulombs. Then we convert the charge to the number of electrons by dividing by the charge of a single electron, resulting in approximately 2.81 × 1 0 21 electrons flowing through the device. This calculation helps us understand the relationship between current, charge, and the flow of electrons.
