Answer:
The time for which the flashlight last is 5.23 hours.
Explanation:
Given that,
One AA battery in a flashlight stores 9400 J, E = 9400 J
Power consumed by the LED flashlight bulbs, P = 0.5 W
We need to find the time for which the flashlight last. The power of a device is given by the energy stored per unit time as :



t = 18800 seconds
or
Since, 1 hour = 3600 seconds
t = 5.23 hours
So, the time for which the flashlight last is 5.23 hours. Hence, this is the required solution.
These are the reactants because they are on the left side of the equation.

Answer: 272.82 drop/tile
Explanation:
Given that the Rain drops fall on a tile surface at a density of 4638 drops/ft2. There are 17 tiles/ft2. How many drops fall on each tile?
Tiles/ft^2 × drop/tiles = drop/ft^2
Tiles will cancel out. Leaving the answer to be drop/ ft^2
Substitutes all the magnitude of the above units.
17 × drop/tiles = 4638
Make drop/tiles the subject of formula
Drop/tiles = 4638/17
Drop/tiles = 272.82
Therefore, 272.82 drop/tile drops fall on each tile?
