An object weighs approximately 125 grams (g), when completely submerged into a box filled with 100 milliliters (ml) of water the volume
rises to 125 milliliters (ml). What is the density of the block?"
pls help!!

Explanation:

The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water

volume = 125 ml - 100 ml = 25 ml

From the question we have

We have the the final answer as

Hope this helps you

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
