What are the major causes of water pollution? Some of the most common sources and causes of water pollution in the nation are detailed below. Runoff from Agricultural Operations. Runoff and Nonpoint Source Pollution. Industrial Activities. Leakage from Underground Storage and Piping. Leaking Sewers. Vehicle Emissions. Landfill Leakage. Hazardous Waste. What are three types of […]

Why does water rise in a capillary tube Class 11? Among common liquids, water exhibits a distinctly high surface tension due to strong hydrogen bonding between its molecules. The rise of a liquid in a capillary tube is due to surface tension which is also known as capillary action. Why do liquids rise in a […]

How does a fixed pulley work? A fixed pulley is a simple machine that uses a wheel with a groove in it and a rope that fits into the groove. The other end of the rope attaches to a load, or the object you’re needing to move. The rope simply moves over the groove of […]

What is the difference between Maksutov Cassegrain and Schmidt Cassegrain? We have to types- Schmidt(SCT) and Maksutov(MAK). The main difference between the Schmidt Cassegrain and the Maksutov Cassegrain is the corrector lens at the front of the tube and secondary mirror. Schmidt Cassegrains are made to have big apertures, and Maksutov Cassegrains usually have small […]

What is the net force in this diagram? If two forces act on an object in opposite directions and they don’t exactly cancel, what is left over is the net force (the difference in the forces). If two(or more) forces act on an object in the same direction, the net force is the sum of […]

Which magnetic field is the strongest? The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center. Is Earth […]

Which field is best in physics? These five great physics concentrations are some of the most popular choices for those majoring in physics. Mathematical Physics. This is a field where the use of mathematic methods are applied to physics in order to solve problems. Astrophysics. Biological Physics. Advanced Physics. Medical Physics. How long does it […]

Will chlorine increase pH? Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero). Can you use vinegar to […]

Why is bisphenol A bad? Research has linked even low-dose BPA exposure to cardiovascular problems, including coronary artery heart disease, angina, heart attack, hypertension, and peripheral artery disease. Findings suggest that this type of exposure could trigger arrhythmias, atherosclerosis, and blood pressure changes. Do Ziploc bags have BPA? BPA Free. SC Johnson’s Ziploc® brand Bags […]

Which area on earth receives the most direct sunlight at what angle? During the summer solstice, the Sun shines most directly on the Tropic of Cancer, 23.5 degrees north of the equator, giving its most direct energy on Earth to the Northern Hemisphere. Which area on Earth receives more light? The equator How azimuth angle […]
