-- What's the volume of a cylinder with radius=1m and height=55m ?
( Volume of a cylinder = π R² h )
-- How much does that volume of water weigh ?
1 liter of water = 1 kilogram of mass
Weight = (mass) x (acceleration of gravity)
-- What's the area of the bottom of that 1m-radius cylinder ?
Pressure = (force) / (area)
Answer:
mass=0.50kg
force=25N
acceleration =?
Now,
force=m×a
25=0.50×a
25÷0.50=a
50=a
acceleration =50m/s^2 answer!!!!
hope this may help you!!!!

Answer:
the reaction force in this situation would be B
Explanation:
The action is the wings pushing down whilst the reaction is the air pushing up which allow the bird to fly .
plz mark brainliest to help me lvl up :P
sorry - late reply...just stumbled across tis...hope u can still use it :)
By the mirror equation: 1/di + 1/do = 1/f
<span>
</span>
<span>where di = distance to image = +12cm (+ for real image)</span>
and do = distance to object = +8cm
Substitute and solve for f, the focal length
<span><span>
1/12 + 1/8 = 1/f
</span><span>
1/f = (8 + 12) / 12 * 8 = 20/96
</span><span>
so f = 96/20 = 4.8 cm</span>
