•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 ‼️

Siapa ambik subjek sains sukan? Subjek yang entahla..sepertinya dilupakan😂

Mesti subjek ni jadi subjek back up A dalam sijil kan?
Kita pun begitu🙈

Chapter 1 (F5): Daya & Gerakan II (Force & Motion II)


Daya geseran: 150 N

Daya selari dgn satah:
= mg sin30
= 1000 (0.5)
= 500 N

Daya tarik: 850 N

Daya paduan:
= daya tarik - (daya geseran + daya selari dgn satah)
= 850 - (150 + 500)
= 200 N

Jawapan: A

ingat.. principal/law huruf besar ya

✨Road to SPM 2024✨

Chapter 5 (F5): Elektrik (Electric)

E = V + Ir
E = I(R + r)
E = 0.2(4.5 + 0.5)
E = 1 V

Tiada jawapan sebab label arus dalam rajah salah

Soalan sebenar I = 1.2 A
E = V + Ir
E = I(R + r)
E = 1.2(4.5 + 0.5)
E = 6 V
