Câu 1: Tại sao khi tách nạn nhân ra khỏi nguồn điện:
a. Người cứu nạn tuyệt đối không được chạm trực tiếp vào người nạn nhân?
Khi nạn nhân tiếp xúc với dòng điện, cơ thể họ có thể dẫn điện. Nếu người cứu nạn chạm trực tiếp vào nạn nhân trong tình huống này, dòng điện từ nạn nhân có thể truyền sang người cứu nạn, dẫn đến nguy cơ cả hai đều bị điện giật.
b. Dùng gậy gỗ khô để gạt dây điện hoặc đẩy nạn nhân ra khỏi nguồn điện mà không dùng gậy kim loại?
Gỗ khô là chất liệu cách điện tốt, nên không dẫn điện. Trong khi đó, gậy kim loại là vật dẫn điện, nếu dùng để gạt dây điện hoặc đẩy nạn nhân, dòng điện có thể truyền qua gậy kim loại sang người cứu nạn, gây nguy hiểm.
Câu 2: Để kiểm soát lượng nước trong đất ở các chậu cây, ta có thể dùng loại mô đun nào?
Để kiểm soát lượng nước trong đất, ta có thể sử dụng mô đun cảm biến độ ẩm đất (Soil Moisture Sensor). Loại cảm biến này đo độ ẩm trong đất và báo hiệu khi đất khô hoặc ẩm ướt.
Câu 3: Theo em các nhận định sau là đúng hay sai, vì sao?
a. Một vài ý kiến cho rằng khi nạn nhân bị điện giật bất tỉnh, việc cạo gió, xoa dầu sẽ giúp bệnh nhân tỉnh lại nhanh hơn.
Nhận định này sai.
Nguyên nhân: Khi nạn nhân bị điện giật, điều quan trọng là phải kiểm tra xem nạn nhân còn thở hay không, đánh giá nhịp tim và thực hiện hô hấp nhân tạo nếu cần thiết. Việc cạo gió, xoa dầu không có tác dụng cải thiện tình trạng của bệnh nhân trong trường hợp này.
b. Trong trường hợp nạn nhân bị bỏng do điện giật, một vài ý kiến cho rằng nên tạt nước vào vết thương để giảm cảm giác bỏng rát.
Nhận định này đúng từng phần.
Nguyên nhân: Không nên tạt nước tùy tiện vào vết bỏng, nhưng có thể dùng nước sạch mát để làm dịu vết bỏng nhằm giảm đau rát. Sau đó, cần che phủ nhẹ vết thương bằng gạc vô trùng và đưa nạn nhân đến cơ sở y tế càng sớm càng tốt.
Câu 4: Hãy kể tên một số mô đun cảm biến thường dùng.
Một số mô đun cảm biến thường dùng bao gồm:
• Cảm biến nhiệt độ (Temperature Sensor).
• Cảm biến độ ẩm (Humidity Sensor).
• Cảm biến ánh sáng (Light Sensor).
• Cảm biến chuyển động (Motion Sensor).
• Cảm biến khí gas (Gas Sensor).
• Cảm biến độ ẩm đất (Soil Moisture Sensor).
• Cảm biến áp suất (Pressure Sensor).
AI Hay chỉ cung cấp thông tin tham khảo và có thể không hoàn toàn chính xác hoặc đầy đủ. Bạn hãy nhớ kiểm tra lại và cân nhắc trước khi áp dụng nhé!
Chắc chắn rồi, hãy cùng giải bài tập này nhé!
Câu 1:
a. Độ sâu của bể nước:
* Tính diện tích đáy bể: 10m x 25m = 250 m²
* Tính độ sâu của bể: Thể tích / diện tích đáy = 750 m³ / 250 m² = 3m
b. Khối lượng nước trong bể:
* Khối lượng riêng của nước: 1000 kg/m³
* Khối lượng nước: Thể tích x khối lượng riêng = 750 m³ x 1000 kg/m³ = 750000 kg
c. Áp suất nước tại đáy bể:
* Công thức tính áp suất chất lỏng: p = d.h (trong đó d là trọng lượng riêng của chất lỏng, h là độ sâu)
* Trọng lượng riêng của nước: d = 10 x khối lượng riêng = 10 x 1000 kg/m³ = 10000 N/m³
* Áp suất tại đáy bể: p = 10000 N/m³ x 3 m = 30000 Pa (Pascal)
Câu 2:
* Tại sao máy bay cần điều chỉnh áp suất trong cabin?
Ở độ cao lớn, áp suất khí quyển bên ngoài máy bay rất thấp. Nếu không điều chỉnh áp suất trong cabin, hành khách sẽ cảm thấy khó thở, chóng mặt, thậm chí ngất xỉu do thiếu oxy.
* Tại sao thợ lặn khi lặn sâu cần trang bị đầy đủ trang thiết bị và mặc đồ lặn?
Khi lặn sâu, áp suất nước tăng lên rất lớn. Nếu không có đồ bảo hộ, cơ thể thợ lặn sẽ bị áp suất đè ép, gây tổn thương phổi, tai và các cơ quan khác.
* Tại sao áp suất khí quyển giảm khi lên cao?
Áp suất khí quyển là do trọng lượng của lớp không khí tác dụng lên Trái Đất. Khi lên cao, lớp không khí phía trên càng mỏng, trọng lượng giảm nên áp suất cũng giảm.
* Tại sao giác mút không dính chặt trên tường nhám?
Giác mút hoạt động dựa trên sự chênh lệch áp suất. Khi ấn giác mút vào bề mặt nhẵn, không khí bên trong bị đẩy ra, tạo ra vùng chân không. Áp suất khí quyển bên ngoài sẽ ép chặt giác mút vào bề mặt. Trên bề mặt nhám, không khí vẫn có thể lọt vào bên trong giác mút, làm giảm sự chênh lệch áp suất, khiến giác mút không dính chặt.
