How do you do apparent weight? The apparent weight of an accelerating object is the vector sum of its real weight and the negative of all the forces that produce the object’s acceleration a = dv/dt. wapparent = wreal – ma. How do you use apparent in a sentence? Certain problems were apparent from the […]
What is the difference between salt and sugar dissolving in water?
What is the difference between salt and sugar dissolving in water? The oppositely charged ends of polar water molecules attract the ions and pull them away, resulting in dissolving. Sugar is made from sucrose molecules which are larger and more complex than the ions in salt (See Teacher Background Lesson 1.2). When sugar dissolved in […]

What is the electric flux through a cube of 1 cm?
What is the electric flux through a cube of 1 cm? Therefore, the net charge enclosed within the cube is zero. Therefore, electric flux is zero. What are the three basic properties of the electric charge? In this section, we will learn about three such properties of point charges; the additivity of electric charge, the […]
How long does radioactive isotope stay in your body?
How long does radioactive isotope stay in your body? The half-lives of radioisotopes used in medicine range from a few minutes to a few days. For example, rubidium-82, which is used for myocardial perfusion imaging has a half- life of 1.26 minutes, while iodine-131, used in thyroid treatment and diagnosis, has a half- life of […]

How much time will it take to learn physics? The thing with high-school physics is that if you know high-school mathematics very well and have atleast average memory, it takes about half a year of about an hour or two daily to be able to ace SAT physics exam. If you struggle with mathematics, learn […]
What did Penzias and Wilson discovery prove?
What did Penzias and Wilson discovery prove? Penzias and Wilson had spotted the CMB, the predicted thermal echo of the universe’s explosive birth. The landmark find put the Big Bang theory on solid ground, suggesting that the cosmos did indeed grow from a tiny seed — a single point — about 13.8 billion years ago. […]
Which circuit is better series or parallel?
Which circuit is better series or parallel? Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the […]
What are the noise control methods?
What are the noise control methods? Extraction, ventilation, cooling, openings in walls and enclosures. Instead of fitting silencers, it is often possible to achieve a 10 – 20 dB reduction in airborne noise from a duct or opening by lining the last bend in the ductwork with acoustic absorbent (foam or rockwool / fibreglass). Which […]
