How do you calculate emergent rays? As the ratio of refractive indices of air and the glass slab remains the same in both cases (though their value gets inverted), the emergent ray is parallel to the incident ray. Therefore, angle of emergence ′e′ is equal to the angle of incidence ′i′. How do you solve […]

Who is known as the father of democracy? Cleisthenes What was the most powerful Greek city-state? Athens Who were the toughest Greeks? The Spartans were widely considered to have the strongest army and the best soldiers of any city-state in Ancient Greece. All Spartan men trained to become warriors from the day they were born. […]

How do you make a homemade water cycle? Put the bowl in a sunny place outside. Using the pitcher or bucket, pour water into the bowl until it is about ¼ Place the mug in the center of the bowl. Cover the top of the bowl tightly with the plastic wrap. Tie the string around […]

What does it mean to say that a rock is permeable? Definition: Some rocks have pores in them, which are empty spaces. If these pores are linked, then fluid, like water, can flow through the rock. If fluid can flow through the rock, then the rock is permeable. Permeable. Porous. Does Clay have a high […]

Why is a gustnado not considered a tornado? Similar to a dust devil, a gustnado really isn’t a tornado at all since it isn’t connected to the cloud base or any rotating wall cloud. They are little whirlwinds that develop off of a thunderstorm outflow or gust front. Is it safe to be buried alive […]

What does the R in safer stand for? SAFER stands for Space, Attitude, Foresight, Eyesight and Responsibility. Course Content: SAFER System of Defensive Driving. Fatigue and Driving. What is the ultimate objective of defensive driving? It is a form of training for motor vehicle drivers that goes beyond mastery of the rules of the road […]

What are the 7 troubleshooting steps? The steps are: identify the problem, establish a theory of probable cause, test the theory, establish a plan (including any effects of the plan), implement the plan, verify full system functionality, and—as a final step—document everything. What are the common computer problems and solutions? Top 10 common computer problems […]

Is free energy possible with flywheel? The AC generator have produce extra electricity by using of flywheel from 1 HP motor. The main advantage of Free energy generator using flywheel is that it can generate energy without used of any extra equipment and this free energy generation is non-hazardous and environmental friendly. How can a […]

What is the kinetic energy formula? Kinetic energy formula KE = 0.5 * m * v² , where: m – mass, v – velocity. How do you find kinetic energy? In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an […]

What is the normal force at the top of a loop? The result is that coaster cars can enter the loops at high speeds; yet due to the large radius, the normal forces do not exceed 3.5 G’s. At the top of the loop, the radius is small thus allowing a lower speed car to […]
