What is effect of intensity of light? Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. Why intensity decreases as distance from the light source increases this […]

What causes static electricity in a person? Static electricity is created when positive and negative charges aren’t balanced. Protons and neutrons don’t move around much, but electrons love to jump all over the place! When an object (or person) has extra electrons, it has a negative charge. Why is my laundry so static? What causes […]

Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]

Can fossils be found anywhere? For example, many fossils form when plant and animal remains are buried by mud, sand, or soil. This helps to preserve the remains long enough for them to form fossils. Still, fossils can be found just about anywhere. From the tops of mountains to the depths of the seas, fossils […]

What are 5 scientific laws? What are the five scientific laws? The five most popular scientific laws are Hooke’s Law of Elasticity, Archimedes’ Principle of Buoyancy, Dalton’s Law of Partial Pressures, Bernoulli’s Law of Fluid Dynamics and Fourier’s Law of Heat Conduction. Do scientific laws and legal laws have anything in common? Scientific laws may […]

How do you calculate a pulley system? To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. In a […]

What is a greedy woman called? The definition of avaricious is greedy and money-hungry. The definition of abstemious is someone who abstains or is moderate, often specifically in their consumption of food and beverage. What do you call a person who asks for money?

What is the correct classification of a mixture? Mixtures can be classified into two main categories: homogeneous and heterogeneous. A homogeneous mixture is one in which the composition of its constituents are uniformly mixed throughout. What is the correct classification of mixture in which both solid and liquid are visible? Whereas a solution in which […]

How do dragsters reduce drag? Because the dragster has parts moving against one another, friction is created. You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body. Drag: Here’s where aerodynamics come into play. How are CO2 dragsters […]
