Based on the picture, which object is denser, the iceberg or the ship?

Eratosthenes of Cyrene measured a solar shadow at about 7.2o from the perpendicular in a well at Alexandria, Egypt, but no solar shadow (0o from the perpendicular) in a well at Syene, Egypt, 490 miles to the south, at midday on the summer solstice. From these measurements, he was able to calculate: that the circumference of the Earth is about 73,500 miles that the circumference of the Earth is about 61,250 miles that the circumference of the Earth is about 49,000 miles that the circumference of the Earth is about 36,750 miles E. that the circumference of the Earth is about 24,500 miles

What if you were designing an experiment testing the impact of different pH levels on plant growth.  What would be the levels of your independent variable and you would need to vary the pH of a factor that plants need for growth such as soil, fertilizer, or water.  What would be your dependent variable; that is, what result would you measure?

The density of a bean is determined by water displacement. multiplying length * mass. dividing mass by volume. multiplying length width *height.
