What are the 4 parts of a comet? A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail. What are three comets? Astronomers have identified three main parts of a comet: the nucleus, coma and tail. What is the biggest part of a comet? nucleus […]

Is the Congo river dangerous? In a country with few paved roads, boarding an overcrowded boat on a treacherous river is a way of life. This weekend, journeys on the dangerous waterways stole the lives of up to 270 people. What country is called the heart of Africa? Malawi What language is spoken in Malawi […]

How do you stop a fission chain reaction? In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by-products which absorb neutrons build up. […]

How do you heat up gold? Try using a propane torch to melt gold. The gold should be placed into a crucible. Be careful to bring the torch down slowly if you have fine powdered gold in the crucible because you could easily blow it around. With a torch, hold the flame well above the […]

What is the net force of a rock falling at constant terminal velocity? Objects falling through a fluid eventually reach terminal velocity . At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. Why does a parachutist does not fall with constant […]

Is ultrasound tech school hard? Difficult but Worth the Effort It takes two years to complete, but the degree from a CAAHEP accredited program qualifies the sonography student to take the ARDMS exams. It is necessary to take required courses like physiology, anatomy, physics, sonography instrumentation and medical terminology. Which is the best ultrasound machine? […]

Why is cohesion in water important? The cohesion of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which helps animals regulate body temperature. How do you use the word cohesive? Cohesive in a Sentence ? To make perfect pie dough, you must mix the ingredients […]

Is too much walking bad for joints? A new study shows that middle-aged men and women who engage in high levels of physical activity — at home and at work as well as at the gym — may be unwittingly damaging their knees and increasing their risk for osteoarthritis. The study involved men and women […]

What do u mean by uniform circular motion? Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Nonetheless, it is accelerating […]

Is N bigger than 2 N? n! eventually grows faster than an exponential with a constant base (2^n and e^n), but n^n grows faster than n! since the base grows as n increases. Every term after the first one in n^n is larger, so n^n will grow faster. Does N 2 grow faster than 2 […]
