Ketika energi listrik dialirkan ke setrika, energi tersebut mengalami perubahan menjadi energi panas. Setrika bekerja dengan memanaskan elemen pemanas di dalamnya, yang kemudian mentransfer panas ke pakaian yang sedang disetrika. Panas ini membantu merapikan dan meluruskan serat-serat pada pakaian. Oleh karena itu, energi listrik berubah menjadi energi panas dalam proses ini.

Turning off electronic equipment when not in use is an example of energy-saving behavior. This means being conscious of energy consumption and taking steps to reduce it by not leaving devices on standby or plugged in unnecessarily. By practicing energy-saving habits like this, individuals can contribute to reducing energy waste and conserving resources.

Bermain layang-layang di dekat tiang listrik dapat membahayakan diri karena ada risiko terkena kabel listrik yang tergantung di sekitar tiang. Jika layang-layang terjebak atau terbang terlalu dekat dengan kabel listrik, bisa menyebabkan kejutan listrik atau bahkan kecelakaan fatal. Oleh karena itu, aktivitas ini harus dihindari untuk menjaga keamanan dan keselamatan diri.

Para petani memanfaatkan energi dari matahari yang berupa panas untuk mengeringkan padinya di tanah lapang.

The correct answer is kipas angin because a fan converts electrical energy into mechanical energy, allowing it to move and create airflow. This is different from the other options, as a television, radio, and lamp do not directly convert electrical energy into mechanical energy for movement.

The correct answer is "Kakak menonton berita di televisi" because watching television requires electricity.

Installing electronic equipment in the house such as bedroom lights and porch lights should be done by adults. Because if the electrical installation is done incorrectly, it can result in a short circuit.

Memasang poster hemat energi di kelas adalah salah satu cara yang efektif untuk mengajak teman-teman di sekolah untuk berhemat energi. Dengan memasang poster, informasi tentang pentingnya menghemat energi dapat disampaikan dengan jelas kepada semua orang di sekolah. Poster tersebut dapat memberikan tips dan saran praktis tentang bagaimana mengurangi penggunaan energi, sehingga dapat menginspirasi teman-teman untuk mengambil tindakan yang sama. Selain itu, poster juga dapat membangkitkan kesadaran dan kepedulian terhadap isu energi yang penting.

The human body is easily shocked by electric current because it contains a high percentage of water. Water is a good conductor of electricity, allowing electric current to easily pass through the body. This is why it is important to be cautious around electricity and take necessary safety precautions to avoid getting shocked.

Choosing to walk when traveling short distances is an example of an action that can save energy. This is because walking does not require the use of any external energy sources such as oil, water, wind, or electricity. By walking, individuals can reduce their reliance on transportation methods that consume energy, such as cars or buses, and contribute to the conservation of non-renewable resources like oil.

The given question asks for the fraction that is equivalent to 1/4. To determine this, we need to find a fraction that has the same value as 1/4. Simplifying the fractions given, we can see that 2/8 is equivalent to 1/4 because both fractions reduce to 1/4 when simplified. Therefore, the correct answer is 2/8.

The given correct answer states that one of the reasons we should use energy wisely and sparingly is so that future generations can also enjoy it. This implies that if we use energy irresponsibly and exhaust all available resources, there will be nothing left for future generations to utilize. Therefore, it is important to conserve and manage energy efficiently to ensure its availability for the future.

By living energy-efficiently, one can reduce their electricity consumption, resulting in lower electricity bills. This means that they will spend less money on electricity, allowing them to save more or allocate their funds to other important expenses.

One of the benefits of coal for human life is as a fuel for power generation. Coal is burned to produce steam, which in turn drives turbines to generate electricity. This makes coal an important energy source for powering homes, industries, and other facilities. It is widely used in many countries as a reliable and affordable source of electricity.

The symbol ">" denotes "greater than," indicating that the value on the left side of the symbol is larger than the value on the right side. In this case, 15/20 is greater than 5/8.

The correct answer is 40. This is because when we divide 5 by 8, we get a decimal value. To convert this decimal value into a fraction, we can express it as 5/8. To find the missing fraction, we need to find a number that, when divided by 64, gives us the same decimal value as 5/8. The number that satisfies this condition is 40, as 40 divided by 64 is equal to 5/8.

The correct answer is "

The correct answer is 45. To find the missing number, we need to multiply the numerator and denominator of 3/4 by the same number to get an equivalent fraction. In this case, we need to find a number that when multiplied by 3 gives 60. The number is 20. Therefore, 3/4 is equivalent to 15/20. So, the missing number is 45/60, which is equivalent to 3/4.

The fraction 3/6 is equivalent to 1/2 because both fractions represent the same value. When we simplify 3/6, we can divide both the numerator and denominator by their greatest common divisor, which is 3. This results in 1/2, which is the same as 1/2. Therefore, the fraction 3/6 is equal to 1/2.

Batubara merupakan sumber energi yang terbentuk dari fosil tumbuhan yang mengalami proses pengubahan selama jutaan tahun. Fosil tumbuhan ini terkubur dalam lapisan tanah dan mengalami tekanan serta panas yang tinggi selama waktu yang sangat lama. Proses ini mengubah bahan organik menjadi batubara, yang kemudian dapat digunakan sebagai sumber energi.

The correct answer is 21/28 and 8/28. This is because when we want to add or subtract fractions, we need to have the same denominator. To do this, we need to find the least common multiple (LCM) of the denominators, which in this case is 28. So, we convert 3/4 to 21/28 by multiplying the numerator and denominator by 7, and we convert 2/7 to 8/28 by multiplying the numerator and denominator by 4. Now, both fractions have the same denominator of 28, and we can add or subtract them.

Rika memiliki pita sepanjang 1/2 meter, sedangkan Alia memiliki pita sepanjang 3/6 meter. Keduanya memiliki pita dengan panjang yang sama karena 1/2 meter dan 3/6 meter dapat disederhanakan menjadi 1/2 meter. Oleh karena itu, jawaban yang benar adalah Rika dan Alia.

Bu Arum menghabiskan briket batubara paling banyak setiap harinya karena dia menggunakan 2/3 Kg setiap hari. Bu Ratna menggunakan 1/4 Kg, Bu Sari menggunakan 2/5 Kg, dan Bu Sintia menggunakan 1/2 Kg setiap harinya.

The fractions are being sorted from smallest to largest. In this case, the fraction with the smallest value is 2/6, followed by 5/10, 3/5, and 2/3.

The correct answer is in ascending order. The fractions are arranged from smallest to largest.
