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
Answer:
23.3%
Step-by-step explanation:
this is the estimated life expectancy of a male person to live to one hundred
X=-53x+378, if you need explanation used ask me.
The exact answer would be 3218.69 meters but since you're rounding upwards, your answer would be D. 3,220 meters.

Use formula: y-y1/x-x1=m(gradient)
so, y=-14x-1
m=-14
y-0/x-2=14/1
y=-14x+28
