Ibu mencampur 2 kg air yang suhunya 100ºC dengan 5 kg air yang suhunya 30ºC. Berapa suhu akhir campuran?
- A.
75ºC
- B.
50ºC
- C.
45ºC
- D.
30ºC
Correct Answer
B. 50ºCExplanation
The given question describes a situation where a person mixes 2 kg of water at 100ºC with 5 kg of water at 30ºC. To find the final temperature of the mixture, we can use the principle of conservation of energy. The heat lost by the hot water is equal to the heat gained by the cold water. By applying the formula for heat transfer, we can calculate that the final temperature of the mixture is 50ºC.Rate this question:

Perhatikan gambar di samping!Sebuah mobil melaju kencang di jalan raya dan menyalib/mendahului mobil lain yang ada di sebelahnya. Jika kecepatan mobil tersebut 144 km/jam dan massanya 1.500 kg. Energi kinetik yang dimiliki mobil tersebut adalah....
- A.
30 kJ
- B.
60 kJ
- C.
1.200 kJ
- D.
12.000 kJ
Correct Answer
D. 12.000 kJExplanation
The correct answer is 12.000 kJ. The kinetic energy of an object can be calculated using the formula KE = 1/2mv^2, where m is the mass of the object and v is its velocity. In this case, the mass of the car is given as 1,500 kg and its velocity is 144 km/h. To convert the velocity to m/s, we divide it by 3.6 (1 km/h = 1/3.6 m/s). Plugging in the values into the formula, we get KE = 1/2 * 1500 * (144/3.6)^2 = 1/2 * 1500 * 40^2 = 12,000 kJ.Rate this question:

Perhatikan rangkaian listrik berikut!Berdasarkan data pada gambar, kuat arus listrik I1 adalah ....
- A.
9 A
- B.
7,5 A
- C.
5,5 A
- D.
4,5 A
Correct Answer
C. 5,5 AExplanation
Based on the given circuit diagram, the current flowing through the resistor R1 is equal to the current flowing through the parallel combination of resistors R2 and R3. Since R2 and R3 have the same resistance value, the current through each of them will be equal. Therefore, the total current I1 can be calculated by adding the currents through R1, R2, and R3. Since the current through R1 is 4.5 A and the current through R2 and R3 is 5.5 A each, the total current I1 is 4.5 A + 5.5 A + 5.5 A = 15.5 A.Rate this question:

Lampu pijar dihubungkan pada jaringan listrik PLN dengan tegangan 220V. Jika kuat arus listrik yang mengalir pada lampu 500mA, energi yang diperlukan lampu untuk menyala selama 10 menit adalah....
- A.
13200J
- B.
66000J
- C.
110000J
- D.
660000J
Correct Answer
B. 66000JExplanation
The energy consumed by an electrical device can be calculated using the formula: Energy (in Joules) = Power (in Watts) x Time (in seconds). In this case, the power of the lamp can be calculated using the formula: Power (in Watts) = Voltage (in Volts) x Current (in Amperes). Given that the voltage is 220V and the current is 500mA (or 0.5A), we can calculate the power as 220V x 0.5A = 110W. Since the time is given as 10 minutes (or 600 seconds), we can calculate the energy as 110W x 600s = 66000J. Therefore, the correct answer is 66000J.Rate this question:

- B.
S-U-S-U
- C.
U-S-S-U
- D.
S-U-U-S
Correct Answer
A. U-S-U-SExplanation
The correct answer is U-S-U-S because when the iron bar KL and MN are brought near a magnet, the ends K and N become opposite poles of the magnet, while the ends L and M become the same poles. Therefore, the correct sequence of poles from K to N is U-S-U-S.Rate this question:

- B.
Perubahan jumlah garis gaya magnet dalam kumparan makin cepat
- C.
Jumlah garis gaya magnet yang memotong kumparan makin besar
- D.
Inti besi pada kumparan memperbesar medan magnet
Correct Answer
B. Perubahan jumlah garis gaya magnet dalam kumparan makin cepatExplanation
The correct answer is "perubahan jumlah garis gaya magnet dalam kumparan makin cepat" because when the bicycle moves faster, the dynamo spins faster, causing a greater rate of change in the magnetic field lines passing through the coil. This induces a larger current in the coil, resulting in a brighter light from the bicycle lamp.Rate this question:

The position of the moon that causes the highest tidal wave is when the moon is directly opposite the sun, which is known as the full moon. This is because the gravitational pull of the moon and the sun align and create a stronger force on the Earth's oceans, causing the high tide to be at its highest point. In option 1, the moon is directly opposite the sun, indicating a full moon position, making it the correct answer.Rate this question:

Correct Answer
B. Besi dapat ditarik magnet adalah sifat fisika, besi berkarat adalah sifat kimia.Explanation
The correct answer is "Besi dapat ditarik magnet adalah sifat fisika, besi berkarat adalah sifat kimia." This is because the ability of iron to be attracted by a magnet is a physical property, as it is related to the magnetic properties of the material. On the other hand, the rusting of iron when it reacts with oxygen in the air is a chemical property, as it involves a chemical reaction between iron and oxygen.Rate this question:
