What do you mean by physical fitness and wellness? Fitness specifically refers to physical health, and is the ability to complete a physical task, or the lack of a physical ailment. Wellness, on the other hand, refers to the balance of a spectrum of health-related elements in one’s life. What is difference between physical fitness […]
Is C3H8 O2 CO2 H2O balanced?
What is the percentage error in the surface area of a sphere?
What is the percentage error in the surface area of a sphere? SΔS=r2Δr=2×4=8% Was this answer helpful? What is percentage error in sphere? Volume of the sphere is V=43πr3. As per the rule for combination of errors for exponents ΔVV=3Δrr. =3 x 0.015. ΔVV=0.045. Percentage error =ΔVV×100=0.045×100=4.5% What is the error in volume? To calculate […]
Why do superconductors float?
Why do superconductors float? At normal temperatures, magnetic fields can pass through the material normally. When a magnet is placed above a superconductor at critical temperature, the superconductor pushes away its field by acting like a magnet with the same pole causing the magnet to repel, that is, “float”—no magical sleight of hand required. Can […]

How does the kinetic theory explain Charles Law?
How does the kinetic theory explain Charles Law? Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. What […]

The altitude of the sun at midday is overall 13.3° higher in Singapore than in New Delhi. Relative humidity levels are 26.1% higher. What is the hottest time of […]
What is the cause of resistance?
What is the cause of resistance? Resistance is caused in a conductor by the free electrons. These free electrons collide with each other and with the ions and atoms that oppose their free movement. This obstruction is known as resistance. Does temperature increase resistance? As electrons move through a metal conductor, some collide with atoms, […]
What are the three main parts of a chemical reaction?
What are the three main parts of a chemical reaction? A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. What are the two types of chemical reactions? Types of Chemical Reactions: Single- and Double-Displacement Reactions Recognize chemical reactions as single-replacement reactions and double-replacement […]
