Which materials make more static electricity when different objects are rubbed up against eachother.
Science is an enterprise that builds and organizes knowledge in the form of testable explanations. Technology is the creation and knowledge of tools and systems that can perform a specific function. You want an example? Electricity. Electrons and how they behave was discovered by scientists and then used by technicians to create many of the incredible inventions we use today. Science discovers stuff, Technology utilizes it.
It is an example of renewable energy.
Negative tag questions are short phrases added to the end of a statement to confirm or check information, typically involving a reversal of the auxiliary verb and subject. For example, in the statement "You're coming to the party, aren't you?" the tag "aren't you?" is negative. They often reflect the speaker's expectation about the listener's agreement or knowledge. Negative tag questions are commonly used in conversational English to engage the listener and encourage a response.
Example: Richard: "Can you please give me a fragmented sentence involving a lever?" Paul: "Certainly: A lever is called."

A testable question in a scientific investigation is one that can be answered through observation, experimentation, or measurement. For example, "Does increasing the amount of sunlight a plant receives affect its growth rate?" can be tested by manipulating sunlight exposure and measuring growth. In contrast, questions based on opinion or beliefs, such as "What is the best flavor of ice cream?" are not testable.
To turn a testable question into a hypothesis, first identify the variables involved in your question. Then, formulate a predictive statement that establishes a relationship between these variables, typically in an "if-then" format. For example, if your question is, "How does sunlight affect plant growth?" you could hypothesize, "If plants receive more sunlight, then they will grow taller." This provides a clear, testable prediction.
Testable problems are specific questions or hypotheses that can be investigated through empirical observation or experimentation. They must be formulated in a way that allows for measurement and analysis, enabling researchers to gather evidence to support or refute them. For example, the hypothesis "Plants grow faster with increased sunlight" can be tested by measuring plant growth under different light conditions. In contrast, questions that are subjective or based on personal beliefs, such as "Is happiness the most important aspect of life?" are not testable in a scientific sense.
Sure! An example of a science investigatory project involving electricity could be testing how different types of fruits can generate electricity by using them as batteries in a simple circuit. The project could involve measuring the voltage output of each fruit and comparing their effectiveness as an alternative source of energy.
To make your hypothesis considered scientific it must have testable and measurable results. Example: If you do an experiment and the results are testable and measurable another person would be able to do the exact same project and come out with the same results.
A testable hypothesis is one that can be verified or falsified through experimentation and observation. For example, "Increasing the amount of sunlight a plant receives will increase its growth rate" is a testable hypothesis, as it can be examined by measuring plant growth under varying sunlight conditions. In contrast, hypotheses based on beliefs or unobservable phenomena, such as "ghosts exist," are not testable through scientific experiments.
A testable hypothesis is a statement that can be supported or refuted through experimentation or observation. For example, "If plants receive more sunlight, then they will grow taller" is a testable hypothesis because it can be evaluated by measuring plant growth under varying sunlight conditions. In contrast, a statement like "Aliens exist" is not easily testable because it lacks specific criteria for observation or measurement.
it is an example of current electricity
One example of current electricity are transmission lines. These bring electricity from power stations to individual houses.
Lightning is an example of static electricity
Generally speaking, as a safe answer, it is because of the scientific method. This method requires you to construct a hypothesis, test this hypothesis by experiment and data to reach a conclusion that can be tested (to the same results) by others. For example: this method can prove that gravity is constant field without reliance on mass - but it cannot be explained how this field reacts to other fields (unified field theory). This method also requires that there is an answer. Some questions such as what is the best beer, prettiest woman, true love, true religion etc. are more opinion than fact with no "right" answer.
A hypothesis is considered testable if it can be evaluated through empirical observation or experimentation. This means it should be framed in a way that allows for the collection of data to support or refute it. A testable hypothesis typically includes clear variables and can be measured or quantified, making it possible to draw conclusions based on the results. For example, stating that "increased sunlight exposure will lead to higher plant growth" is testable because it can be examined through controlled experiments.
