Noah drops a rock with a density of 1.73 g/cm3 into a pond. will the rock float or sink? explain your answer.

The rock will sink in the water because it has high density than water.

Explanation:

As we know that the density of water is

And in the given question the density of the rock is  .

And also it is known that any object which has higher density than the water it will sink or if it is lower density than water it will float.

Now in the given situation the density of the rock is greater than the density of the water.

Therefore, the rock will sink in the water because of high density than water.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
