What does light do in the photoelectric effect? In the photoelectric effect, light incident on the surface of a metal causes electrons to be ejected. The number of emitted electrons and their kinetic energy can be measured as a function of the intensity and frequency of the light. Which experiment proved the particle nature of […]

How many total atoms are in a glucose molecule?
Does increasing volume increase rate of reaction?
Does increasing volume increase rate of reaction? A larger surface area per volume ratio increases the areas of contact between reactant particles. This increases the chances of successful collisions. Thus the rate of reaction is increased. Why does volume not affect rate of reaction? As the gas sample volume increases (e.g. as we add more […]
Why do masses attract each other?
Why do masses attract each other? Any object having some mass will attract another object having mass. this is because of gravity. When two objects ahving some mass are separated by some distance then force of gravity acts between them and tends to keep them close that means it is always attractive in nature. How […]

What are the 3 laws of flight?
What are the 3 laws of flight? The Third Law states that “For every action, there is an equal and opposite reaction.” It was developed by Sir Issac Newton in the 17th century. The four forces of flight are always acting on an aircraft: thrust (forward), drag (rearward), lift (up), and weight (down). How is […]
What causes Oxbow?
What causes Oxbow? An oxbow lake forms when a river creates a meander, due to the river’s eroding bank . After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck by sedimentation of silt, cutting off the meander […]
Is Van de Graaff generator a capacitor?
Is Van de Graaff generator a capacitor? A leyden jar is a storage capacitor which can withstand very large voltages. A van de graaf generator is a charge pump which can generate large voltages, but at very small currents. When you connect a van de graaf to a leyden jar, the jar accumulates the energy […]
