well power is equal to work multiplied by time so .. 900j divided by 15 s will give you 60 Watt as your answer
The answer is E, graduated cylinder.
Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.
And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.
And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.
Answer:
E) 2
Explanation:
The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
Answer:
Wildlife is living organisms, like plants and animals that live anywhere in the world that they are not isolated in a certain area.
Explanation:
Each wildlife creature lives in an ecosystem that their bodies can tolerate and be able to survive in.
- Penguin´s bodies are adapted to keep them warm in Antarctica, if they are in warm climates they would overheat.
- Cold-blooded animals like iguanas cannot live in cold climates because their body temperature would be according to what they feel, so living in cold climates would cause them to die from hypothermia.
