a football team snaps the ball from their 10 yard line. The quarterback throws to a receiver who lined up 20 yards to the right of the quarterback and ran straight downfield. If the pass was 25 yards, how far downfield was the receiver when he caught the ball?

If you want a real hero, who's handsome, compassionate and intelligent (never mind all these movie stars or 'nouveau riche'), he's the fella! A model, a professor, a doctor, does cancer research and brings aide to countries in need....and much more besides no doubt...he's a STAR! LOOK HIM UP AS REAL LIFE HERO for your kids..he's amazing. His brother just died in a freak accident which we're all really sad about, he was also destined to be an astronaut.

So if I find a way to somehow travel faster than light I can supposedly go back in time, right? But If I were to go back in time, I would either travel backwards to the point where I went to the speed of light, then go faster than light, then go back in time to the point where I went faster than light and I would be stuck in an endless cycle of speeding up and going back in time to speed up again? Or would I travel to the point of the speed of light, (And according to science, time stops when you reach the speed of light) and time would pause, and I would be stuck there for all eternity? And If I was stuck like that, and someone were to pass by the area where I achieved light speed, what would they see? Would they see me continuing at the speed of light, or would I simply vanish?

Can someone explain to me how to answer this problem. I am a little stuck...

Light is shining perpendicularly on the surface of the earth with an intensity of 900 W/m2. Assuming all the photons in the light have the same wavelength (in vacuum) of 637 nm, determine the number of photons per second per square meter that reach the earth.

Thanks!

If freezing point depression is based on colligative properties, meaning the concentration of the solute and not its chemical identity determine how much the freezing point is lowered. Then why, for example, is calcium chloride more effective than sodium cholride at melting water?

evaluate the integral from 0 to 1 at x^2(sqrt[4]{e^x}) dx

To clarify the notation of the problem you are solving. The number 4 after the sqrt means its ^4sqrt(e^x) . It is the fourth root of e^x
