My father-in-law, expert of all things, has said that ethanol is used for cars in Brazil and accounts for most energy needs in Brazil.

Is this true ???

I cannot bear this weather anymore, and while the heat usually lasts until November/early December, when does it actually start raining or the clouds start blocking the sun around in these parts of the Bay Area? (San Pablo, near San Francisco.)

Does anyone know? I haven't actually kept track.

This problem has me stumped...if someone could get the process started for me:

A car is on a dry road with a velocity of 32 m/s. The driver brakes and the car halts with an acceleration of -8.00 m/s^2. On an icy road, the acceleration would have been -3.00 m/s^2. How much further would the car have skidded on the icy road?

Don't answer with PI or stuff like that. I would like to know the formal definition.

A jetliner is landing with a speed of 69 m/s. Once the jet sets down, it has 750 m of runway to slow down to 6.1 m/s. What is the average acceleration during landing?

The photon not being a particle itself .But a lumped mass of particles moving at variable frequencies. Hence representing value of the radiation energy of the micromass particles of light? is that correct?

I've been told that the Standard Model accurately describes all of the fundamental forces except for gravity, but there is a lot of flaw within the theory, right? For example, one of the fundamental particle, neutrino, has mass, but it travels faster than the speed of light, which is impossible according to Einstein's Theory of Special Relativity. Also, if the Standard Model believes in supersymmetry, and all the particles we know have a symmetrical part to it, (electron - positron) could there possibly be an anti-universe that exist? Please discuss and post your thoughts

1. A circular city has radius r km and average population density p people per sqaure km. In 2002, the population was 3 million, the radius was 25 km and growing at 0.1km per year. If the density was increasing at 200 people per square km per year, find the rate at which the total population of the city was growing at that time.

So I kinda set up the problem first.
population =3
r=25km
dr=0.1km/yr
dp=200people/km^2/yr

so is the population a function of r and p? I got stuck, and don't know which method i should use. Can anyone gimme some ideas?

If i were to wear sunglasses and was looking directly at the sun, which had exploded. Would i see the sun how it was 100's of years ago or i would see a flash and the destruction instantly ???

If the light takes 100's of years to get here then i think it would have the same effect. CORRECT ???
