What would happen if a cyclist pedals harder? Push harder on the pedals to increase the force pushing you forwards. Your speed will increase until the opposing forces increase to balance your larger forward force. What forces are acting on a cyclist? There are 4 forces that act on a cyclist and determine how fast […]

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 […]

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 […]

Which properties do all metalloids share? Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their ability to conduct heat and electricity. They are shiny like metals, but brittle like nonmetals. What […]

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 […]

What does temperature change mean? Noun. 1. temperature change – a process whereby the degree of hotness of a body (or medium) changes. advection – (meteorology) the horizontal transfer of heat or other atmospheric properties. climate change, global climate change – a change in the world’s climate. How does temperature change happen? The Earth’s surface […]

Is Surya Grahan good or bad? A Total Surya Grahan or Total Solar Eclipse occurs when the moon passes between the Sun and the Earth, obscuring Earth’s view of the sun completely. It is a rare phenomenon and over the years, it is believed that this eclipse can have a harmful impact on the human […]

What is equal to the angle of reflection? Large telescopes use reflection to form an image of stars and other astronomical objects. Figure 1. The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point […]
