What is meant by one dimensional elastic collision? Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved. […]

Is DNA prokaryotic or eukaryotic? Prokaryotic Cells Prokaryotic Cells Eukaryotic Cells Nucleus No Yes DNA Single circular piece of DNA Multiple chromosomes Membrane-Bound Organelles No Yes Examples Bacteria Plants, animals, fungi Are viruses prokaryotes? Prokaryotes and eukaryotes are distinguished on the basis of their cellular characteristics. Viruses are considered neither prokaryotes nor eukaryotes because they […]

What makes it easier to push heavy things answer? Answer: When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So […]

What is the property of minerals that reflects light? Luster What are the two major properties of minerals? A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical […]

Is a galaxy close to the Milky Way moving away from us slowly or quickly? As we look out into the Universe, we see galaxies moving away from us faster and faster. The more distant a galaxy is, the more quickly it’s moving away. To understand why this is happening, go and get a balloon […]

What is the direction of net force in circular motion? The final motion characteristic for an object undergoing uniform circular motion is the net force. The net force acting upon such an object is directed towards the center of the circle. The net force is said to be an inward or centripetal force. What is […]

How do you fix a flooded atomizer? Fold the paper towel several times and hold it against the end of the atomizer. Blow gently through the drip tip until the atomizer stops gurgling. Reassemble the e-cigarette. You should now be able to resume e-smoking. How do you tell if your coil is flooded? The characteristic […]

What are the four stages in the life cycle of a low mass star? Stars about the size of our sun go through the same first four stages as does any other star. They begin their lives as a nebula, then become a Protostar, eventually becoming a main sequence star and finally a red giant. […]
