Jelaskan apa yang dimaksud dengan gas alam
Gas alam adalah campuran gas-gas hidrokarbon yang ditemukan di bawah permukaan bumi. Biasanya terdiri dari metana bersama dengan sejumlah kecil gas lain seperti etana, propana, butana, dan nitrogen. Gas alam merupakan sumber energi utama yang digunakan untuk berbagai keperluan seperti pemanasan, memasak, dan pembangkit listrik.

220 v G 1 = 50 mA Berdasarkan gambar tersebut, Jika kuat arus listrik yang mengalir pada kumparan primer sebesar 50 mA, maka besar kuat arus listrik yang mengalir pada kumparan sekunder adalah......
a. 2.0 A
b. 2.2 A
c. 10 A
d. 0,1 A
mau jwbn dngn langkah langkah
Jawaban:
Untuk menjawab pertanyaan ini, kita perlu memahami konsep transformator.
Dalam transformator, berlaku hubungan:
Vs/Vp = Ns/Np
Dimana:
Vs = Tegangan sekunder
Vp = Tegangan primer
Ns = Jumlah lilitan sekunder
Np = Jumlah lilitan primer
Berdasarkan informasi yang diberikan:
- Tegangan primer (Vp) = 220 V
- Arus primer (Ip) = 50 mA = 0,05 A
Untuk mencari arus sekunder (Is), kita dapat menggunakan rumus:
Ip x Np = Is x Ns
Karena tidak diberikan informasi mengenai jumlah lilitan primer (Np) dan jumlah lilitan sekunder (Ns), maka kita tidak dapat menghitung Is secara langsung.
Namun, kita dapat menggunakan prinsip transformator ideal, dimana:
Vs/Vp = Ns/Np = Is/Ip
Sehingga, jawaban yang paling tepat adalah:
d. 0,1 A
Karena dalam transformator ideal, jika arus primer (Ip) = 0,05 A, maka arus sekunder (Is) = 0,1 A.
Jawaban:
b. 2,2 A

persamaan sumbu simetri grafik fungsi y = 3 - 10x- x^2
X = 5
X = -b/2a
X = - (-5)/2.1
X = 10/2
X = 5
tolong kasi cara nya sekalian ya
Jawab:
Penjelasan dengan langkah-langkah:
x² - 2x - 3 = 0
(1)x² + (-2)x + (-3) = 0
ax² + bx + c = 0
a = 1
b = -2
c = -3
x₁ + x₂ = -b/a
x₁ + x₂ = -((-2)/1)
x₁ + x₂ = -(-2)
x₁ + x₂ = 2.
Jadi, hasil dari x₁ + x₂ adalah 2.
Semoga membantu.
12. Sebuah pipa U diisi dengan air (massa jenis = 1.000 kg/m³), kemudian dimasukkan zat cair lain hingga mengisi 10 cm bagian kiri pipa. Jika diketahui beda ketinggian permukaan zat cair adalah 1 cm, maka besarnya massa jenis zat cair tersebut adalah .... a. 0,9 kg/m³ b. 9 kg/m³ c. 90 kg/m³ d. 900 kg/m³
Jawaban:
Untuk menyelesaikan masalah ini, kita dapat menggunakan prinsip keseimbangan tekanan dalam fluida. Karena pipa U terisi dengan dua cairan yang tidak bercampur dan berada dalam keseimbangan, tekanan di kedua ujung pipa harus sama.
Karena ketinggian permukaan zat cair yang dimasukkan adalah 10 cm dan beda ketinggian permukaan adalah 1 cm, maka tinggi kolom air di sebelah kiri adalah 10 cm - 1 cm = 9 cm.
Tekanan yang dihasilkan oleh kolom zat cair adalah ρgh, di mana ρ adalah massa jenis zat cair, g adalah percepatan gravitasi, dan h adalah tinggi kolom zat cair.
Tekanan yang dihasilkan oleh kolom air di sebelah kanan adalah ρ(1 m³)g(10 cm) = ρ(1 m³)(10^(-1) m)(9.8 m/s²) = 9.8ρ Pascal.
Karena kedua tekanan harus sama, maka ρ(1 m³)(10^(-1) m)(9.8 m/s²) = 9.8ρ.
Dengan demikian, kita dapatkan ρ = 9 kg/m³.
Jadi, jawabannya adalah b. 9 kg/m³.
