OH !! lupa nak habaq, soalan ni 10 markah tau 😁😄

🌷Cadangan Jawapan 👇

☁️CIRI-CIRI ꩜ .ᐟ

📝CAKERA PARABOLA : Diameter piring parabola yang besar// permukaan piring parabola yang licin

📝DARJAH PUTARANNYA : Mampu berputar sehingga 360°

📝KEDUDUKAN PENERIMA ISYARAT : sama dengan panjang fokus

📝JARAK PENERIMA ISYARAT DARI CAKERA PARABOLA : sama panjang dengan titik fokus

📝GELOMBANG ELEKTROMAGNET YANG DIKELUARKAN : Gelombang Mikro

🌺PENERANGAN ꩜ .ᐟ

📲Dapat menerima signal dengan lebih banyak.

📲Dapat menerima Isyarat daripada pelbagai/banyak arah.

📲Supaya semua isyarat tertumpu pada titik fokus

📲Dapat menerima Isyarat dengan maksimum//dengan lebih jelas

📲Gelombang mikro ; mempunyai frekuensi tinggi dan tenaga yang tinggi

kenapa kena guna Gelombang Mikro? kenapa bukan Gelombang Radio ek?🤔

🗣️”sebab gelombang mikro tidak mudah terbelau berbanding dengan gelombang radio”

lagi? kalau dari segi frekuensi and panjang gelombang pulak macam mana?

🗣️”okay senang je,
semakin bertambah f, frekuensi
semakin berkurang λ, panjang gelombang”

🗣️”Gelombang Mikro (microwave) mempunyai frekuensi dan tenaga yang tinggi, oleh itu, panjang gelombangnya pun rendah. Sebab tu Gelombang Mikro ni lagi jelas, sebab dia tak mudah terbelau”

okay!! faham

💡PROTIPS :

untuk soalan macam ni, tecaher I pernah cakap, kalau repeat jawapan atas, still dapat markah BUT jangan repeat soalan balik…alamatnya bye-bye jelah free marks korang tu…😁

—- tapi make sure jawapan yang korang ulang tu, kena lah dengan situasi yerkk…janganla pulak jauh tersasar dari radar tu balik, fahim tum?

buat pasal topic ni…tetiba pulak admin teringat pasal MH370 😢💔

guys..before tidur ni saya nak share sikit contoh soalan..at least we learn something new/revised benda yang kita dah terlupa before tidur. simple² je ! 💞

sharing from previous class. harap bermanfaat !

-physics
•paper 1
-pls master formula and definition. definition is the most vital element untuk paper 1 ngn paper 2.

-from formula n definition,u can master soalan concept,comparing n relating, decision making, modification.

-as well as soalan relationship (the higher,the lower, directly proportional,graphs)

-kalau tak baca topic tu sekali pun, trust me formula n definition have done nothing but a life saver for me dalam paper 1

🟣 SOALAN K1 [NEGERI9 2023]

try to answer this question. kalau tak faham boleh tanya !

🟣 SOALAN K1 [KELANTAN 2023]

happened to bump onto this question and got confused sebab dlm textbook dia explain induction cooker and yes induction cooker and electrical cooker aren't the same thing even though both are electrical-powered and lazimnya look just the same.

•induction cooker
-uses electromagnetic induction to generate heat directly into the cooking pot/pan
-highly energy-efficient since heat is generated directly.
-👩‍🍳 requires spesific cookware made up of ferromagnetic materials (eg:cast iron/stainless steel)
-uses high-frequency alternating current (ac)

meanwhile,
•electrical cooker
-uses resistive heating element to convert electrical energy>heat energy.
-the heat will be transferred from heating element to the pot and then to the food. (heating element>pot>content(food)
-less efficient bc more heat loss to the surrounding compared to induction cooker.
-👩‍🍳works with any type of cookware as long as it conducts heat.
-ingat tak non-ohmic conductor? electrical cooker uses high-resistivity,coiled,nichrome resistance wire

kenapa guna resistance wire dalam electrical cooker?
➡️sebab resistance wire resists electric current to produce heat
➡️ resistance wire perlu
•coiled
•high resistivity
•nichrome material
so the heating element will lasts longer and only need a short period of time to heat up the food

this is strictly NOT an exact way to answer the question ‼️
