All planes need air to pressure under their wings to stay up in the air. As they move forward. The higher air pressure underneath their wings pushes them upward and gives them lift. The smooth, streamlined shape of the plane allows the air to flows easily over its surface. This helps to reduce the drag caused by the air pushing against the plane and allows it to move rapidly through the air. Planes move forward using engines. This movement is called thrust. Moving forward keeps a stream of moving air passing over the wings. If the engines fail, the planes will begin to descend very quickly. The air above the wing moves faster, so it is at a lower pressure than the air under the wing.The air under the wing moves more slowly and is slightly squashed, so it is at a higher pressure than the air above the wing. The planes stay up in the air when?

5. Semua jawaban benar

Jawaban yang benar adalah: A. There is air pressure under their wings.

Dilansir dari Ensiklopedia, all planes need air to pressure under their wings to stay up in the air. as they move forward. the higher air pressure underneath their wings pushes them upward and gives them lift. the smooth, streamlined shape of the plane allows the air to flows easily over its surface. this helps to reduce the drag caused by the air pushing against the plane and allows it to move rapidly through the air. planes move forward using engines. this movement is called thrust. moving forward keeps a stream of moving air passing over the wings. if the engines fail, the planes will begin to descend very quickly. the air above the wing moves faster, so it is at a lower pressure than the air under the wing.the air under the wing moves more slowly and is slightly squashed, so it is at a higher pressure than the air above the wing. the planes stay up in the air when There is air pressure under their wings.

Pembahasan dan Penjelasan

Menurut saya jawaban A. There is air pressure under their wings adalah jawaban yang paling benar, bisa dibuktikan dari buku bacaan dan informasi yang ada di google.

Menurut saya jawaban B. A stream of moving air passes over their wings adalah jawaban yang kurang tepat, karena sudah terlihat jelas antara pertanyaan dan jawaban tidak nyambung sama sekali.

Menurut saya jawaban C. The engines move faster adalah jawaban salah, karena jawaban tersebut lebih tepat kalau dipakai untuk pertanyaan lain.

Menurut saya jawaban D. The wings move forward adalah jawaban salah, karena jawaban tersebut sudah melenceng dari apa yang ditanyakan.

Menurut saya jawaban E. Semua jawaban benar adalah jawaban salah, karena setelah saya coba cari di google, jawaban ini lebih cocok untuk pertanyaan lain.

Kesimpulan

Dari penjelasan dan pembahasan serta pilihan diatas, saya bisa menyimpulkan bahwa jawaban yang paling benar adalah A. There is air pressure under their wings.
