Why are graduated cylinders not accurate?
Why are graduated cylinders not accurate? Similar to cylinders, beakers are graduated with volume measurements. In that case, why is a graduated cylinder more accurate than a beaker? The volume marks on a beaker are only approximate values, and therefore only provide whole numbers. What is a graduated cylinder is used to measure? Liquid volume […]
What is the meaning of Brownian motion?
What is the meaning of Brownian motion? Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations.

How would your present weight change if Earth had twice the mass that it does now?
How would your present weight change if Earth had twice the mass that it does now? Twice the mass means twice the acceleration due to gravity which will increase acceleration by the factor of 2 thus the weight will be double the time. What will happen if the Earth is bigger than the current size? […]
Why is the charge of MgCl2 +2?
Why is the charge of MgCl2 +2? Explanation: Salts are electrically neutral. In magnesium chloride or calcium chloride or ferrous chloride, the charge on the metal centre is equally balanced by the chlorides. Cl− bears a single negative charge, and thus 2 equiv of chloride are required to give a salt. Why MgCl2 is soluble […]

Why do we always have to include uplift with erosion?
Why do we always have to include uplift with erosion? Description. Erosional processes and rates of uplift strongly influence the overall shape of eroding landscapes. Uplift of a mass above base level increases the potential energy of the land. Uplift steepens stream profiles, energizing the streams, which then cut into the land mass. How does […]

Why electromagnetic wave can travel in vacuum?
Why electromagnetic wave can travel in vacuum? The propagation of electromagnetic waves either in a certain medium or in vacuum is due the the mutual changes between the electric and magnetic field. These variations in electric and magnetic fields fields lead to the transfer of the energy which is carried by the EM wave. What […]
