Assuming that humans are at the top of the heap in terms of consciousness, where does the bottom lay? Is there consciousness in lower life forms, animals, plants, bacteria, fungi, and could consciousness possibly extend further to exist in non-living matter or even as a mass-less, body-less energy? What are your thoughts?

My son asked me and I told him that there a giant magnet keeping us on the ground. Any suggestions on how to refine my answer?

Even when we are at the beach on a hot day or have just gotten out of a hot shower. Is it because the water cools downs and then absorbs heat from your body? Or could it be that your hairs are stuck down so piloerection isn't effective? Or simply that our bodies are exposed with little or no clothing on?

kim pushes a lawn spreader across a lawn by applying a force of 95N along the handle that makes an angle of 60.0 w/ the horizontal.
a. what are the horizontal and vertical components of the force?
b. The handle is lowered so it makes an angle of 30.0 degrees w/ the horizontal. Now what are the horizontal and vertical components of the force?


Really, i've looked for help in my book/ notes/ internet... i don't get it...

also, does anyone know any sites that can help ppl w/ physics?

ok... how would i solve this:

Two 15-N forces act concurrently on point P. Find the magnitude of their resultant when the angle between them is:

a. 0.0
b. 30.0

Can you explain this problem to me????

A plane travels on a heading of r.o for a distance of 3.00x10^2 km. How far north and how far east does the plane travel????


thank you also.... do you have any sites that will help people who don't understand physics?

Ok, I'm not here so that people can do my homework; I just need some help so please don't say I just want answers. I'm having trouble with this question on Relative velocity...it's an easy question but something is throwing me off:

An airplane wants to travel to Town A which is 650 km north of the airport. The wind velocity 125 km/h west. If the plane can fly at a velocity of 475 km/h relative to the air, determine:
a) the velocity of the plane relative to the ground and the heading (direction) that the plane must travel.
b) the time that the plane is in the air.
c) how far off course the plane would be if the pilot flew the plane ignoring the wind.

How can I even draw the two vectors..I understand that I can draw a line going 125 km/h west but the plane relative to the air 475 km/h doesn't even give the direction...can someone please help me solve it

I heard this from a friend of mine, that in vacuum when light hits the mirror it doesn't bounce back -it acts like coal or anything black in air. But i don't really believe this, and am too lazy to calculate the effects, so i just ask you guys. If anyone knows somehing WORTHY OF TELLING about this, then please, do so.

if it were possible to travel faster than the speed of light...

and, get to where the universe as yet to expand to...

would do you think it would look like?

would it be just...white...nothingness?

we all know that when things are heated, temperature changes. but while the physical state is changing temperature does not change though heating is continued. so what is that that couses temperature to change that stops acting while things are changing their state?

I think it was Archimedes who found that when an ice cube is placed in a glass of water, the volume of water displaced is equal to the volume of water the ice cube will take up when melted. This means that the water level in the glass will stay constant even when the ice cube melts.

If this is true, then why does the earth's sea level rise as the polar ice caps are melting?

Surely the amount of water displaced by the ice caps will be equal to their volume once they melt and so the sea levels would stay constant.

Would someone please explain why the world's sea levels are rising???

If so does that mean that the laws of Physics must undergo a revision?

Here is what I mean... Suppose everything in our universe was doubled in size... People... the Earth... the Stars... EVERYTHING... would the laws of physics stay the same? Would anything be different? Would we be able to tell that somehow that everything is now doubled in size?
