(1) All gravitational and magnetic forces are repellent. (2) The gravitational force repels, while the magnetic force attracts. (3) Magnetic force is repulsive, while gravitational force is attractive. (4) Both the gravitational and magnetic forces are attractive.
30 A television remote control is used to send electromagnetic radiation waves to a television receiver. The fact that electromagnetic radiation (1) decreases in amplitude and frequency as it travels from the remote control to the television is shown by this contact. (2) amplitude decreases and frequency increases (3) amplitude increases and frequency decreases(4) amplitude increases and frequency decreases
40 To compress the spring in a pop-up toy, a child exerts 0.20 joule of effort. What is the highest vertical height that the toy can reach after the spring is released if the mass of the toy is 0.010 kilogram?

## What is physical information?

Physics classes in high school are usually taken at the end of your high school career. You’ve probably taken chemistry, biology, and earth science, and you might have noticed that the distinctions between them made science seem disjointed and difficult to understand. Physics gives you the opportunity to bring everything together under one unifying science that describes everything from electron activity to planet motion. Since physics is so fundamental to all other sciences, some schools are promoting a program in which students take physics first, then all of the other sciences that students usually encounter in high school. It’s worth thinking about whether this is a choice at your high school. If you’re still in high school, though, physics still provides an excellent opportunity to understand the interconnectedness of the natural sciences.
Physics can be overwhelming for even the best students, perhaps because of its ability to cross disciplines. High school physics classes will most likely be at least as difficult as your previous science lessons, and they will reward preparation and hours spent on lab reports or studying for long-answer test questions. The ability to reduce complex problems to a series of familiar, basic equations is one of the keys to success in a high school physics class.

In much of North America, twelfth grade, also known as senior year or grade 12, is the final year of high school. It’s also known as Year 13 or Class 12 in other parts of the world. Students in most countries are normally between the ages of 17 and 18. In some countries, there is a thirteenth grade, while in others, there is no such thing as a 12th grade or year. The final year in high school is usually referred to as twelfth grade (graduation year).
Year 12 is the name assigned to the twelfth grade in Australia. Students in New South Wales are usually 16 or 17 years old when they reach Year 12 and 17–18 years old when they graduate (end of year). The majority of Year 12 students aspire for an ATAR (Australian Tertiary Admission Rank). The OP (Overall Position, which only applies to students in the state of Queensland) was used until the beginning of 2020. [1] Both of these allow/allowed them to enroll in university courses.

Who can imagine a weight of 1103 kilograms? Is it a molecule, a pin tip, a pepple, a rock, or something else entirely? It’s a fantastic one-sentence visual. This, in my view, is “encyclopedic content” taken too far. This is a helpful tidbit that only takes one sentence to express. What are the views of others? 7 January 2006, 07:54 Nastajus (UTC)
I concur with Bob. My students have weighed paper clips in science class and found that they vary in weight from.5 to 1.5 grams. The weight of a plastic pen cap (think Bic) is exactly 1.0 gram. Shouldn’t we inform the rest of the world? For evidence, please visit my website:
While the gram has its defects, they are not as serious as those of the kilogram. The gram is a much easier unit to deal with in exponential notation. For example, water has a density of 1 gram per cubic cm, and the earth’s mass is 10E27.8 grams (approximately) and the sun’s mass is 10E33.3 grams (approx.). And it works well for both small and large values in the cgs calculations. 19:42, 24 August 2009, WFPM (talk) (UTC)
