The resultan of the two forces can be found by subtracting the smaller force from the larger force. In this case, since Umar's force is 25 N and Amir's force is 20 N, the resultan is 25 N - 20 N = 5 N.

The correct answer is "tegak, sama besar". When an object is placed in front of a flat mirror, the image formed is virtual, erect (tegak), and the same size (sama besar) as the object. This is because a flat mirror reflects light rays without any distortion, resulting in an image that appears behind the mirror and is the same size as the object.

Based on the given food web, label number 1 and 2 represent the relationship between a mouse and a small bird. This can be inferred because in a food web, an arrow pointing from one organism to another indicates that the first organism is being consumed by the second organism. In this case, the arrow from label number 1 (mouse) points towards label number 2 (small bird), indicating that the small bird preys on the mouse. Therefore, the correct answer is "tikus dan burung kecil" (mouse and small bird).

The correct answer is ginjal. The kidneys are responsible for filtering the blood and removing waste products in the form of urine. They play a crucial role in maintaining the body's fluid balance, regulating blood pressure, and eliminating toxins from the body. The urethra is the tube that carries urine from the bladder out of the body, while the ureter is the tube that connects the kidneys to the bladder. The liver is involved in many metabolic processes but is not directly responsible for filtering the blood and producing urine.

The correct answer is "dalam dosis yang tepat" because fertilization will only increase crop yields if it is used in the right amount. Using too much or too little fertilizer may not have the desired effect on the harvest. Therefore, it is important to use fertilizers in the appropriate dosage to achieve optimal results.

The correct answer is Panjang, Massa, Waktu. These three quantities (length, mass, and time) are considered fundamental or base quantities in the International System of Units (SI). They are independent of other quantities and cannot be defined in terms of any other physical quantities. Other quantities such as force, area, volume, and velocity can be derived from these base quantities.

The given options describe different examples of behavioral adaptations in various animals. The correct answer states that whales often surface in order to breathe. This behavior is an adaptation that allows whales to take in oxygen from the air, as they are mammals and need to breathe air to survive. By coming to the surface, whales can inhale and exhale, replenishing their oxygen supply and removing carbon dioxide from their bodies. This behavior is essential for their survival in an aquatic environment.

The density of a substance is defined as its mass per unit volume. In this question, the mass of the aluminum is given as 120 grams and the volume is given as 60 cm³. To find the density, we divide the mass by the volume: 120 grams / 60 cm³ = 2 gr/cm³. Therefore, the correct answer is 2 gr/cm³.

Dalam contoh ini, ikan remora yang menempel pada ikan hiu mendapatkan manfaat dari naungan dan perlindungan yang diberikan oleh ikan hiu tanpa memberikan manfaat atau merugikan ikan hiu tersebut.

The correct answer is "posisi bumi berada di antara matahari dan bulan pada satu garis lurus". This is because a lunar eclipse occurs when the Earth is directly between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

The correct answer is xylem. Xylem is a plant tissue responsible for transporting water and minerals from the roots to the leaves. It is composed of specialized cells called tracheids and vessel elements, which form long tubes that allow for efficient water movement. The xylem also provides structural support to the plant.

The largest pressure is indicated by image A.

The specific heat capacity of water is 1 calorie/gram°C. To calculate the amount of heat required to raise the temperature of 5 grams of water from 10°C to 40°C, we can use the formula Q = mcΔT, where Q is the amount of heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, we get Q = 5g * 1 cal/g°C * (40°C - 10°C) = 5g * 1 cal/g°C * 30°C = 150 calories. Therefore, the correct answer is 150 Kalori.

The correct answer is H - I - H - G - H. This sequence represents one full vibration or oscillation. The pattern starts with H, then moves to I, then back to H, then to G, and finally back to H, completing one full cycle of vibration.

When plastic is rubbed against hair, electrons are transferred from the hair to the plastic. This transfer of electrons results in the hair becoming negatively charged, while the plastic becomes positively charged. Therefore, the correct answer is "elektron pindah dari rambut ke plastik" (electrons move from hair to plastic).

A collection of networks with similar functions will form an organ.

The correct answer is 48 Joule because the work done on an object is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. From the given image, it can be observed that the force applied on the block is larger and the distance it moves is also larger compared to the other options. Therefore, the work done on the block is the highest, which is 48 Joule.

The correct answer is 1, 3, and 5. These options involve efforts related to intensification in agriculture. Pemberantasan hama dan penyakit (eradication of pests and diseases) is a form of intensification as it aims to protect crops from damage. Pemupukan (fertilization) is also a form of intensification as it involves adding nutrients to the soil to enhance plant growth. Teknik tumpang sari (intercropping) is another form of intensification as it involves growing multiple crops in the same field simultaneously to maximize land use. Therefore, options 1, 3, and 5 are the correct choices.

The correct answer is "tegangan primer lebih kecil daripada tegangan sekunder" (the primary voltage is smaller than the secondary voltage). This is because a step-up transformer is designed to increase the voltage from the primary side to the secondary side. In a step-up transformer, the number of turns in the secondary coil is greater than the number of turns in the primary coil, resulting in a higher voltage output. Therefore, the primary voltage is smaller than the secondary voltage.

The correct answer is 6 - 1 - 3 - 4 - 2. This is the correct order of the passage of impulses in the normal movement. First, the impulse is received by the receptor (6), then it is transmitted to the sensory nerve (1). From the sensory nerve, the impulse is sent to the central nerve (3) where it is processed. After processing, the impulse is then transmitted to the motor nerve (4) which controls the effectors (muscles and glands). Finally, the impulse reaches the effector (2) and results in the desired movement.

Therefore, the correct answer is c - g as it represents the unit of wavelength.

Pernyataan 1 dan 3 sesuai dengan proses seleksi alam. Pada pernyataan 1, belalang yang berwarna hijau dapat bertahan hidup karena mereka dapat menyamarkan diri di antara rumput yang berwarna hijau, sedangkan belalang yang berwarna kuning akan mudah terlihat dan dimakan oleh pemangsanya. Pada pernyataan 3, kupu-kupu Biston betularia yang hidup di Inggris setelah revolusi industri lebih banyak berwarna hitam karena polusi asap menyamarkan pandangan pemangsanya, sehingga kupu-kupu dengan warna yang lebih terang menjadi lebih mudah terlihat dan dimakan oleh pemangsanya.

In the given image, number 2 represents the male reproductive organ of the flower. This is known as the stamen, which consists of the filament and anther. The filament holds up the anther, where pollen grains are produced. The male reproductive cells, known as sperm, are contained within the pollen grains. Therefore, number 2 is the correct answer as it represents the part of the flower that functions as the male reproductive organ.

The given question asks for the magnitude of current (I1). The correct answer is 4 A. This means that the magnitude of current flowing in the circuit is 4 Amperes.

The given information states that 60 Coulombs of electric charge flows through a wire in 5 minutes. To find the electric current, we need to divide the amount of charge by the time taken. Therefore, the electric current is 60 Coulombs / 5 minutes = 12 Coulombs per minute. To convert this to Amperes, we need to divide by 60 (since 1 Ampere = 1 Coulomb per second). Therefore, the electric current is 12 Coulombs per minute / 60 = 0.2 Amperes.

The correct answer is 1 and 3. The number of wire turns in a coil and the speed of motion of the magnet or coil are factors that affect the magnitude of electromagnetic induction.
