Why does NASA launch rockets from Florida? It was selected for two reasons: the fact that it is relatively near to the equator compared with other U.S. locations; and the fact that it is on the East Coast. An East Coast location was desirable because any rockets leaving Earth’s surface and traveling eastward get a […]
How big should my rocket fins be?
How big should my rocket fins be? The design formula further provides that width of each fin should be at least 1.25 times the diameter of the rocket body. The cut and try method of fin design is probably the most widely used and the most successful. Can a rocket be too stable? Being over-stable […]
Why is Aluminium foil a bad insulator?
What is the apparent size of the moon?
What are the two basic principle of electromagnetism?
What are the two basic principle of electromagnetism? Electromagnetic survey methods are based on two fundamental principles: Faraday’s law of electromagnetic induction and the fact that electric currents generate magnetic fields, expressed in Ampère’s law. What are the properties of magnetism? Magnets exhibit the following properties: All magnets have two poles: the North Pole and […]
What are the characteristics of sensory receptors?
What are the characteristics of sensory receptors? Sensory receptors that share a common location often share a related function. Sensory receptors code four aspects of a stimulus: modality (or type), intensity, location, and duration. Cutaneous touch receptors and muscle spindle receptors are both mechanoreceptors, but they differ in location. Which type of cell is sensory? […]
What are the two basic components of a coating?
What are the two basic components of a coating? Two primary components of a liquid applied coating. Pigment and Vehicle (Resin or Binder and Solvent). Three methods by which a coating provides corrosion control. What are the different methods of coating? Typical Coating Techniques Dip Coating. Cost effective process provides uniform high quality coating on […]
Why linear regression is called linear?
Why linear regression is called linear? Given a data set of n statistical units, a linear regression model assumes that the relationship between the dependent variable yi and the p-vector of regressors xi is linear. The model remains linear as long as it is linear in the parameter vector β. Why is regression linear? Simple […]
What is the only Fsii additive approved for turbine fuels?
What is the only Fsii additive approved for turbine fuels? Innospec’s FSII-41 ice inhibitor is based on Di-Ethylene Glycol Monomethyl Ether (DiEGME) chemistry, the preferred solution for today’s market. The additive is suitable for use in either aviation turbine fuel (jet fuel) or aviation gasoline, subject to specification requirements and approvals. What is Prist made […]
What is the formula of electric force?
What is the formula of electric force? Calculate the electrostatic force using the formula: F = K[q1 x q2]/D^2 where K is coulombs constant, which is equal to 9 x 10^9 Nm^2/C^2. The unit for K is newtons square meters per square coulombs. What is an example of repulsive force? For example, the force between […]
