Answer:
Workdone = 2450Joules
Step-by-step explanation:
Let the top of the aquarium be at height 0.
Let the bottom of the aquarium be at height 1
F = mg = 2p◇x × g
F= 2000◇x × 9.8
F = 19600◇x
Workdone = 19600xdx
Total workdone = Integral (limits 0.5 -0)19600×dx
Total work = [9800x^2]^0.5
Total work= 9800× 0.5^2 = 2450 Joules
For this case we must pose a verbal problem equivalent to the following expression:
So, we have:
The sum of double a number plus five.
We propose the expression:
A number subtracted from the sum of double the same number plus five equals twenty-six.
Answer:
A number subtracted from the sum of double the same number plus five equals twenty-six.
Answer:
Contour lines
Step-by-step explanation:
A series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level are called CONTOUR lines, or just contour.
A contour line (also called isoline) is a line that indicates points at the same elevation on the map, showing you a representation of the terrain's elevation (hills, mountains, canyons and so on). You will find those lines on specialized maps, like topographic maps, which are different than road maps.
The arrow is at a height of 48 ft after approximately 0.55 seconds and after 5.45 seconds.
<em><u>Explanation</u></em>
The given formula is: 
If the initial velocity is 96 ft/s , that means 
For finding the time the arrow takes to reach a height of 48 ft, we will plug 
into the above formula. So......
So, the arrow is at a height of 48 ft after approximately 0.55 seconds and after 5.45 seconds.
Well, if we put everything together we have gone .25 of a mile in 72 seconds.
Since .25 is a quarter of a mile (1/4) we can estimate that in 288 seconds the car has traveled one mile. We got 288 by multiplying .25 by 4.
