What is the first step in obtaining minerals? The first step in the production stage is recovering the minerals; this is the process of extracting the ore from rock using a variety of tools and machinery. The second step is processing; the recovered minerals are processed through huge crushers or mills to separate commercially valuable […]
Which wire has more resistance thick or thin?
Which wire has more resistance thick or thin? The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional . Which wire produce […]
What happens when two pure substances are mixed?
What happens when two pure substances are mixed? If we take two or more pure substances and mix them together, we refer to this as a mixture. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture. What most commonly […]
What causes a comet to move?
What causes a comet to move? Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. How do I track comets? How to See Comet […]

Is mutual inductance always positive?
Is mutual inductance always positive? The mutual inductance LM can be either positive or negative depending on the polarity of the mutual voltage in reference to the direction of the inducing current. Note that the mutual voltage in the second coil can be positive or negative based on the orientation of the coils. Why is […]
