Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. Why does like charges attract each […]
Why are we weightless in space?
Why are we weightless in space? Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. The force of gravity is the only force acting upon their […]
Which substance is used as coolant in radiator?
Which substance is used as coolant in radiator? Ethylene glycol (antifreeze) is used in the cooling of a car radiator during the winter because it has a much lower freezing point than water. The specific heat of antifreeze (pure or mixed with water) is lower than that of pure water. But in the summer water […]
How force is directly proportional to length of a conductor?
How force is directly proportional to length of a conductor? Current flowing through the wire as the current in the conductor (I) is proportional to the force. Angle between the conductor and the external magnetic field as this determines the conductor’s effective length, or the vertical component of the length. Does length of wire affect […]

What is Aeolian soil?
What is Aeolian soil? Aeolian sandy soils are those soils which are typically developed from sandy parent material through the action of wind. Such soils generally have a sandy layer 1 m or more thick, consisting mainly of well-sorted fine sand, with over 80% of particles in the size range 0.25–0.05 mm (Chen, 1992). What […]
