Hi -

I learned that any body "in orbit" is really in continuos free fall due to gravity.

But if so, why hasn't the moon crashed into the earth? An apple when dropped only takes a second to fall...

Before the movie, wasn't the phrase used frequently in the automotive industry?

Does anyone know what is the origin of the phrase "Dead on Balls Accurate" ?

Thanks,

Yes, when a body experiences a force: is there anyway to experimentally determine wheather it is due to gravity or due to acceleration?

For example, if a space station is rotating (& the...

Does Einstein's theory of relativity say that there is anyway to experimentally measure a difference between a force experienced by gravity and a force experienced by acceleration ?

It depends on wheather you "know" that you are in a spaceship which is traveling as you say.

Since everything appears to be perfectly as normal to people on the spaceship (as long as they don't...

Hi -

What exactly is a bazillion? Or is it just an expression?

1e12 = trillion
1e15 = zillion
1e18 = gazillion

simplyfying the 2nd eq:
y=-4-5/2x

substitute back into the 1st eq :
2x - 4(-4 -5/2x) = 40

solve it for x
x = 2 and subst back into the original eq & y=-9

both the integers (when you add 1 to 10e200 and when you add 3 to 10e200) are prime

I think that the numbers

(10e200 + 1) and (10e200 + 3)

Would yield a 400 digit number when multiplied together

In the case of lines intesecting at the poles, then they wernt really parallel in the first place.

The very definition of "parallel" means that they don't intersect

Does anyone know if you can reduce/eliminate "standby" electrical power usage of major appliances if you flip off the circuit breaker for them when not in use?

I have heard that unplugging...

"Radio" waves & "light" waves are both the same phenomena : forms of electromagnetic radiation (only with different wavelengths)

The discriminant (b^2 - 4ac) is positive so both roots are real

It is impossible to identify the constant of integration. The solution which you seek lacks a closed form .

x(2 + 2/x)

but that boils down to the samw thing, so the prev expression is simplified as far as it goes I think

Hi -

Does anyone know what is the origin of the phrase "dead cat bounce" ?

This fiscal term is used frequently, however I always wondered the origin of this phrase was - & whether it is a...

No, government can't actually create anything. They can only destroy.

Dogbeball might be fun to play and watch while the participants are drunk, however they would not be able to dodge any of the balls so the game would be over too quickly

The wording in the question was off : in that the seizures I was referring to are partial seizures that happen during sleep and are not like grand mal seizures. The seizures only cause fairly small...

Dear HVAC Technician -

How can I increase the blowing power from some of the vents into the house?

Some of the vents blow just fine, whereas others hardly blow at all (just a trickle of air...

The election is over and the decision has been made. Obama's success now represents America's success. If Obama fails then that is the same as if America fails.

In regards to just your generally question about the sign (direction) of the electrical force:

Coloumb's law equation gives the unsigned MAGNITUDE of a force between two electrically charged...

For the sake of America: I hope Obama succeeds too

Well, I many lose my job... hey but at least I might get a wellfare check.

Pay it

Dear HVAC Technician -

I have a Bryant Standard Programmable Thormostat (TSATBBSAC01), how can I actually set the thermostat to run the heating program that I enter?

I can set a desired heating...
