sekeping cakram berjari-jari r=0,1 m memiliki vektor normal permukaan n yang membentuk sudut fluks 30° terhadap medan listrik homogen e yang besarnya 2×10³. berapakah fluks listrik yang melalui cakram ?
Answer (4)
x = $1.56 = 12 oz y = x + $0.02 = oz
1.56 ÷ 12 = 0.13 15 (0.13 + 0.02) = 2.25
$2.25 = 15y
To calculate the cost of a 15-ounce package of brand Y, we first need to determine the cost per ounce of brand X, which is given as $1.56 for 12 ounces. Then, we can find out how much more brand Y costs per ounce and use this information to calculate the total cost for 15 ounces.
Step 1: Calculate the cost per ounce for brand X
$1.56 / 12 ext{ ounces} = $0.13 ext{ per ounce}
Step 2: Determine the cost per ounce for brand Y
$0.13 ext{ per ounce (brand X)} + $0.02 ext{ (additional cost)} = $0.15 ext{ per ounce for brand Y}
Step 3: Calculate the cost for 15 ounces of brand Y
$0.15 ext{ per ounce} imes 15 ext{ ounces} = $2.25
Therefore, the cost for a 15-ounce package of brand Y is $2.25.
The cost for 15 ounces of Brand Y is $2.25. This is calculated by first determining the cost per ounce of Brand X and then adding the additional 2 cents. Brand Y's cost per ounce is $0.15, so for 15 ounces, it totals to $2.25.

Jawaban:hitung fluks listrik yang melalui cakram tersebut. Konsep Dasar: - Fluks Listrik: Fluks listrik (Φ) adalah ukuran jumlah garis medan listrik yang menembus suatu permukaan.- Rumus Fluks Listrik:- Φ = E . A . cos θ- Dimana:- E = Medan listrik (N/C)- A = Luas permukaan (m²)- θ = Sudut antara vektor normal permukaan dan medan listrik Diketahui: - Jari-jari cakram (r) = 0,1 m- Sudut antara vektor normal dan medan listrik (θ) = 30°- Besar medan listrik (E) = 2 x 10³ N/C Langkah-langkah Penyelesaian: 1. Hitung Luas Permukaan Cakram (A):- Luas lingkaran = πr²- A = π (0,1 m)² = π (0,01 m²) = 0,01π m²- Nilai π kurang lebih 3,14, maka A = 0,01 * 3,14 m² = 0,0314 m²2. Hitung Cosinus Sudut (cos θ):- cos 30° = √3 / 2- Nilai √3 kurang lebih 1,732, maka cos 30° = 1,732 / 2 = 0,8663. Hitung Fluks Listrik (Φ):- Φ = E . A . cos θ- Φ = (2 x 10³ N/C) * (0,0314 m²) * (0,866)- Φ = 2000 * 0,0314 * 0,866- Φ = 54,4168 Nm²/C- Dibulatkan menjadi 54,42 Nm²/C Jawaban:Fluks listrik yang melalui cakram tersebut adalah sekitar 54,42 Nm²/C.
