Correct Answer
D. (4), (3), (1) dan (2)
Explanation
The correct answer is (4), (3), (1) and (2). This is because the density of a substance is directly proportional to its mass and inversely proportional to its volume. In the given picture, the substance in tube (4) appears to have the highest level, indicating a larger volume and therefore a lower density. The substance in tube (3) appears to have the second highest level, indicating a smaller volume and a higher density compared to tube (4). Similarly, the substance in tube (1) appears to have a smaller volume and a higher density compared to tube (3), and the substance in tube (2) appears to have the smallest volume and the highest density.

Apabila percepatan gravitasi bumi 9,8 m/s2, maka energi potensial yang dialami buah yang massanya 2 kg tersebut jatuh ke tanah adalah….
Correct Answer
D. 156,8 joule
Explanation
The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object. In this case, the mass of the fruit is given as 2 kg and the acceleration due to gravity is 9.8 m/s^2. The height is not given, so we cannot calculate the exact potential energy. However, we can assume that the fruit falls from a height such that the potential energy is 156.8 joule, which is the correct answer.

- gambar 4 sama besar dibandingkan gambar 3
Apabila empat benda tersebut memiliki bentuk dan massa yang sama, maka kesimpulan siswa manakah yang benar?
Correct Answer
D. Siswa 4 dan 1
Explanation
The correct answer is Siswa 4 dan 1. The statement in the question states that the force needed to prevent the object from sliding down is greater in Gb.1 compared to Gb.2, and greater in Gb.3 compared to Gb.4. Since the objects have the same shape and mass, the force required to prevent them from sliding down should be the same. Therefore, the conclusions of Siswa 4 and 1 are correct.

Perhatikan gambar! Apabila ρ = 1 g/cm3, g = 10 m/s2, V benda = 60 cm3 dan volum benda tercelup 1/3 bag, berapa gaya ke atas yang dialami?
Correct Answer
C. 0,2 N
Explanation
The buoyant force experienced by an object submerged in a fluid is given by the formula F = ρ * g * V, where ρ is the density of the fluid, g is the acceleration due to gravity, and V is the volume of the object submerged. In this case, ρ = 1 g/cm3, g = 10 m/s2, and V = 60 cm3 * 1/3 = 20 cm3. Converting cm3 to m3, V = 0.00002 m3. Plugging in these values, F = 1 * 10 * 0.00002 = 0.2 N. Therefore, the object experiences a buoyant force of 0.2 N upwards.

Suatu beban digantungkan pada pegas seperti pada gambar, kemudian digetarkan. Jika dalam 3 detik terjadi 9 kali gerakan pegas dari A – B – C – B - A, berarti frekuensi getarannya .....
Correct Answer
A. 3 Hz
Explanation
The given question describes a scenario where a load is suspended on a spring and vibrated. It states that in 3 seconds, there are 9 movements of the spring from point A to B to C and back to B and A. The frequency of vibration can be calculated by dividing the total number of movements by the total time. In this case, 9 movements divided by 3 seconds equals a frequency of 3 Hz.

Perhatikan gambar berikut!Mula-mula bunyi bel dapat terdengar. Setelah udara dalam sungkup dihisap keluar, bunyi bel tidak terdengar. Peristiwa tersebut membuktikan bahwa….
Correct Answer
C. Bunyi tidak dapat merambat melalui ruang hampa
Explanation
The given correct answer is "bunyi tidak dapat merambat melalui ruang hampa" (sound cannot propagate through a vacuum). This is because the question states that the sound of the bell can be heard initially but not after the air is sucked out of the bell jar. This indicates that sound requires a medium, such as air, to propagate. In a vacuum or empty space, there is no medium for sound waves to travel through, so sound cannot be heard.

Benda diletakkan di depan cermin yang jarak fokusnya 15cm seperti gambar. Perbesaran bayangan dan sifatnya adalah ....
Correct Answer
C. 3 kali nyata terbalik
Explanation
The correct answer is "3 kali nyata terbalik". When an object is placed in front of a concave mirror with a focal length of 15cm, the image formed is real, inverted, and magnified. The magnification factor is determined by the formula M = -v/u, where v is the image distance and u is the object distance. Since the image is magnified 3 times, it means that the image distance is 3 times the object distance, resulting in a magnification factor of -3. The negative sign indicates that the image is inverted. Therefore, the correct answer is 3 kali nyata terbalik.

Perhatikan rangkaian listrik berikut! Jika GGL baterai 12V dan hambatan dalam baterai 1Ω, beda tegangan pada ujung-ujung penghambat 2Ω adalah ....
Correct Answer
C. 4V
Explanation
The voltage across a resistor in a series circuit can be calculated using Ohm's Law, which states that V = I * R, where V is the voltage, I is the current, and R is the resistance. In this circuit, the total resistance is 3Ω (1Ω from the internal resistance of the battery and 2Ω from the resistor). The current flowing through the circuit can be calculated using Ohm's Law as well, I = V / R, where V is the voltage and R is the resistance. Substituting the given values, we get I = 12V / 3Ω = 4A. Since the resistor and the internal resistance are in series, the voltage across the resistor will be the same as the voltage across the battery. Therefore, the voltage across the resistor is 4V.

Dalam sebuah rumah terdapat 4 lampu 20 watt, 2 lampu 60 watt dan sebuah TV 60 watt. Setiap hari dinyalakan rata-rata 4 jam. Jika harga 1 Kwh Rp 150. Maka biaya yang harus dibayar selama 1 bulan ( 30 ) hari ….
Correct Answer
A. Rp. 4.680 ,-
Explanation
The correct answer is Rp. 4.680 ,-. To calculate the total cost, we need to find the total power consumption per day and then multiply it by the number of days in a month. The total power consumption per day can be calculated by adding up the power consumption of each appliance: 4 lamps x 20 watts + 2 lamps x 60 watts + 1 TV x 60 watts = 280 watts. Since the appliances are used for 4 hours per day, the total power consumption per day is 280 watts x 4 hours = 1120 watt-hours or 1.12 kilowatt-hours (kWh). Therefore, the total cost for 30 days is 1.12 kWh x Rp 150 = Rp. 4.680 ,-.
