HI! I am new to this forums and this is my first post. Look, I have a homework problem that I hope you guys know how to figure it out.
Here it is:
Recently, Dr, Frank has suggested that EArth may be pelted by thousands of house-sized comets. When Frank first considered the idea of mini-comets falling to earh , he no doubt tried to make a quick calculation. Comets are like dirty snowballs that evaporate when they enter the atmosphere. Oceans have accumulated from these comets over the years. Use the following information to estimate what percent of Earth's oceans could be accounted for givena constant bombardment by comets over the last 4 million years:
1 year=365.25 days
1 ton=2000 lbs
1 pound = 454 grams
Density of water = 1g/ml
15000 minicomets hit earth every day
Earth's oceans occupy 1.36 billion km3
1 mini comet = 30 tons
Help is greatly appreciated, thanks
