How can you tell if something is moving at a constant speed? Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt x = x 0 + vt , where x0 represents the position of the object at t=0 […]
What are the geologic processes?
What are the geologic processes? Geological processes – volcanoes, earthquakes, rock cycle, landslides Plate boundaries include transform, convergent , divergent. The evidence for this theory includes fossils, similar rock layers, and GPS measurements of the continents. What are the 4 types of plate movements? There are four types of boundaries between tectonic plates that are […]
What is the meaning of precession?
What is the meaning of precession? : a comparatively slow gyration of the rotation axis of a spinning body about another line intersecting it so as to describe a cone. What is an example of precession? Precession is a change in the orientation of the rotational axis of a rotating body. An important example is […]
What is the formula for short circuit current?
What is the formula for short circuit current? This applied voltage divided by the rated primary voltage (times 100) is the impedance of the transformer. Example: For a 480 Volt rated primary, if 9.6 volts causes secondary full load current to flow through the shorted secondary, the transformer impedance is 9.6/480 = . 02 = […]

Needed for vision, healthy skin and mucous membranes, bone and tooth growth, immune system health Vitamin D Needed for proper absorption of calcium; stored in bones What are […]
Which of the following is the example of double displacement reaction?
Which of the following is the example of double displacement reaction? Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. These reactions are […]
What are the horizontal and vertical components of acceleration of a body thrown horizontally with uniform speed?
What are the horizontal and vertical components of acceleration of a body thrown horizontally with uniform speed? Sine the speed is uniform, the acc.in horizontal direction is ZERO. The vertical component will be 9.8 m/s (g) as gravity always acta on a body in downward direction. What are horizontal and vertical components of acceleration? What […]
