Which distance is more important from the fulcrum for a lever? The farther the effort is away from the fulcrum, the easier it is to move the load. If the distance from the effort to the fulcrum is greater than the distance from the load to the fulcrum, then the lever has a mechanical advantage. […]
Which element has the strongest coulombic attraction?
Which element has the strongest coulombic attraction? Magnesium ion has a higher coulombic attraction compared to the coulombic attraction of Sodium. This is why Magnesium ion is more reactive than Sodium Ion. (Sodium has a +1 charge and Magnesium has a +2 charge. Magnesium has a higher coulombic attraction than sodium.) Which best describes the […]
Do all atoms have an electric charge?
Do all atoms have an electric charge? All atoms have an electric charge. When a given number of positively charged particles combines with an equal number of negatively charged particles, an electrically neutral particle is formed. Did the miners at Chernobyl die? Out of the miners who worked at Chernobyl, some have survived and some […]
What are the condition for system to be in mechanical equilibrium?
What are the condition for system to be in mechanical equilibrium? For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force. What two […]
Why does my body lose heat so fast?
Does buoyant force depends on density?
Does buoyant force depends on density? According to Archimedes principle, the buoyant force of a partially immersed body is equal to the weight of the displaced liquid. Therefore the buoyant force depends upon the density of the fluid and the submerged volume of the body. Does buoyant force depends on density of object? Notice how […]
What type of stress can pull rocks apart?
What type of stress can pull rocks apart? tensional Why do people make grave rubbings? The rubbing forms a type of souvenir. Gravestone rubbing can be used to teach about local history. The stone’s condition, art, and inscription can tell what was going on in an area at a specific time. Studying multiple gravestones in […]
What are the 2 types of supernovae?
What are the 2 types of supernovae? There are two basic types of supernova, called (boringly enough) “Type I” and “Type II”. Type I: supernovae WITHOUT hydrogen absorption lines in their spectrum. Type II: supernovae WITH hydrogen absorption lines in their spectrum. What does a Type 1 supernova leave behind? Type I (especially Ia) supernova […]
What does a woman in flux mean?
What does a woman in flux mean? If your likes, dislikes, attitudes, dreams, and even friends are changing all the time, you may be in flux. Flux can also mean being unsure about a decision. Suppose you just had a great job interview and suddenly your friend invites you to go to Australia with her. […]
Is velocity constant in free fall?
Is velocity constant in free fall? Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity. Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity […]
