Question

A leak in a water tank causes the water level to decrease by 3.6×10−23.6×10−2 millimeters each second. About how many millimeters does the water level in the tank decrease in 5 hours, or 1.8×1041.8×104 seconds? Drag and drop the values to the boxes to express the answer in scientific notation.

Answer 1

Answer:
`6.48 * 10^2`

Explanation:

Since, According to the question,

The leak in a water tank causes the water level to decrease by
`3.6* 10^(-2)` millimeter

That is , in 1 second it decreases
`3.6* 10^(-2)` mm

⇒ In
`1.8* 10^4` seconds it will decrease
`3.6* 10^(-2)* 1.8* 10^4` mm

⇒ In
`1.8* 10^4` seconds it will decrease
`6.48* 10^(2)` mm
