If the upper semicircle has a resistance of 2R Ω and the lower one has a resistance of R Ω, the magnetic field at the center of the circle is… a) \( \frac{\mu_0 I}{6a} \) b) \( \frac{\mu_0 I}{4a} \) c) \( \frac{\mu_0 I}{a} \) d) \( \frac{\mu_0 I}{12a} \) https://xelin.pages.dev/posts/exc-kebumian/ Mon, 06 Nov 2023 08:57:29 +0700 https://xelin.pages.dev/posts/exc-kebumian/ Soal Kebumian OSN-K | astro 1 Bayangkan di alam semesta kita ada dua buah batu masing-masing memiliki massa 5 kg dan terpisah 1 m serta saling mengorbit satu sama lain. Berapa periode orbit batu itu? (konstanta gravitasi \((G)=6,6743 \times 10^{-11} m^3 kg^{-1} s^{-2}\)) Soal Kebumian OSN-K | astro 2 Internal waktu antara dua oposisi berurutan dari Mars adalah 779,9 hari. Hitung setengah sumbu panjang planet Mars dalam orbitnya mengelilingi matahari. https://xelin.pages.dev/posts/exc-induksi-elektromagnet/ Mon, 06 Nov 2023 08:56:29 +0700 https://xelin.pages.dev/posts/exc-induksi-elektromagnet/ Number 1 Question: An E.M.F. can be induced by … . a) Change in the magnetic field only b) Change in the area of cross section only c) Change in angle between magnetic field and area only d) Change in the magnetic field, area, or angle between them Reveal Answer Answer: d Explanation: emf=-dϕ/dt. We know ϕ flux is the dot product of the magnetic field vector and area vector. ϕ=BAcos(θ), hence if either of the three, that is, magnetic field, area, or angle changes, the emf will change, flux changes due to which emf can be induced. https://xelin.pages.dev/posts/electromagnetic-induction/ Tue, 31 Oct 2023 15:56:29 +0700 https://xelin.pages.dev/posts/electromagnetic-induction/ Elektromagnetik Induksi Elektromagnetik induksi adalah prinsip dasar dalam bidang elektromagnetisme yang merevolusi pemahaman kita tentang listrik dan magnetisme. Hal ini pertama kali ditemukan oleh Michael Faraday pada tahun 1830-an dan lebih lanjut dijelaskan oleh Heinrich Lenz, mengarah pada pengembangan berbagai perangkat dan teknologi yang telah menjadi bagian integral dalam kehidupan sehari-hari kita. 1. Hukum Faraday Hukum Faraday tentang induksi elektromagnetik dijelaskan oleh persamaan berikut: $$\varepsilon = -N\frac{d\Phi}{dt}$$ Di mana: \(\varepsilon\) adalah gaya elektromotif (EMF) yang diinduksi dalam volt (V). https://xelin.pages.dev/posts/english/phrasal-verb/ Tue, 31 Oct 2023 10:56:29 +0700 https://xelin.pages.dev/posts/english/phrasal-verb/ While they were on holiday their house was broken ______ and some valuable paintings were stolen.
