Is it possible that we are wrong about why the planet's temperature is going up? I mean has anyone thought about the fact that our planet weighs a lot more than it used to because of all the people living that have been saved by doctors. Last time I checked our solar system was mapped out by gravity. So isn't possible that because of our increased weight we are being pulled closer to the sun?

Is it something to do with the pressure i.e. the atmospheres inside the can, compressing the gas into liquid form?

A blimp, suspended in the air at a height of 500 feet, lies directly over the line from Soldier Field to the Adler Planetarium on Lake Michigan. If the angle of depression from the blimp to the stadium is 32 degrees and from the blimp to the planetarium is 23 degrees, find the distance BETWEEN Soldier Field and the Adler Planetarium.

Question 1. Say you live in a country where the voltage is 200-210V, purposely lower in order to meet the demands of a country. Is there any harm or effect on the appliance which is rated 220-240V in the long run or the short run.

Question 2. Say if you have an appliance that has been rated 220V and the supply voltage coming into that appliance is 240V. Is there any effect/harm done to the appliance in the long run or short run.


Links to websites in order to understand these phomena about electricity would be of great help. thanks

Gravitational field strength increases above the surface of the Earth. Yet it decreases below the surface of the Earth, why is this? I know it has something do with having a force above you.

I know that events like the moon landing were very important to American history...but do you think the millions (possibly billions?) of dollars spent each year on the space program is really worth that money? Couldn't it go to something more important?

If you take a bowling ball and a ping-pong ball and dropped them in a vacum they would both fall at the SAME speed. Mass plays no part in the speed of the objects. So how in the world would one's mass have to be increased to achieve the speed of light? Gravity is a result of lots of mass, the bigger the mass the more the gravity. I can see incresing power to get closer to the speed of light but how does that increase one's mass? Does a car going at 100 mph have more mass than a car going at 20mph? It may have more energy but not more mass. Can someone help me with this or point me in the right direction?

It is said that increased cardiac output may be an early feature, followed by increased peripheral resistance and normalisation of cardiac output.
The increased peripheral resistance is developed in a compensatory manner to prevent the raised pressure being transmitted to the capillary bed where it would substantially affect homeostasis.
What i don't understand is why is peripheral resistance developed when cardiac output increased? How does this mechanism work?
And does this only apply to essential hypertension?
Thanks.

Joe will roll a pair of dice until he rolls a 7 (sum of 2 numbers). Let X be number of times he will roll without getting a 7.
(For example, if on the third roll Joe first rolls 7, then X=2.)
What is the expected value of X?

[hints:
let p(x) denote probability that X=x.
The expected value will be an infinite series, (0)p(0) + (1)p(1) + (2)p(2) + ... .
After the formula for p(n) is determined, compute the series (remember 1 + x + x^2 + x^3 + ... = 1/(1-x), if |x|<1)
Take the derivative of both sides.

It's a black and white bug/insect...I know, it's a black and white copy. Well, My camera on my phone was a little too fuzzy. So I picked 'em up and plopped him on the copy machine, scanned the photos, and there we have it. He's about 2 1/4 inches long, 1/2 inch wide, and one of his antennae is 1 1/4 inches long. He really is black and white....Notice the little horns on his neck, if you can...very tiny. Antennae look like ants legs. He has a split shell, I'm assuming has wings because of it. I'm very curious about this one.
