You need to put the inverse square law to use. Earth's solar radiation intensity is of value 1357 Watts/meter^2. This is a standard value known by the solar energy industry. This is the EXTRATERRESTRIAL value, which is put to use for equipment on the Moon or in Earth orbit. At ground level...

This question is so vague that all except for meteors and meteorites are correct. Had you written "meteorOIDS" instead, that would be a correct answer...just as correct as the answer they want you to choose (Comets). PLUS...the fact that we have three "meteor*" words is unnecessary. They are...

1000 years is nothing in terms of a star's "lifetime". Our sun has existed for 4.5 billion years and it will exist for another 4.5 billion years. There are many blue stars in Orion, and blue stars have shorter lifespans than the sun...but still their lifespans are substantially larger than...

z direction. It is arbitrarily chosen that area vectors point perpendicular to the surface of area, in order that they make sense in vector calculus.

To sketch sine curves, you can usually get a clue by knowing the meanings of terms in the general equation. y = A*sin(omega*theta + phi) + y0 A is amplitude omega is angular frequency phi is phase offset y0 is the mid-line offset In any case, your sine curve should vertically range from y0 -...

resistivity geometry temperature does affect resistance as well...BUT, temperature's effect is already embedded in the resistivity of the material at the temperature.

Because you do work on the swing by applying a force to the seat which is "in tune" with its oscillation like a pendulum. You use conservation of momentum to do so. Your feet are the body against which you propel your torso and seat when you pump your legs. The tension in the swing's ropes or...
