Answer:
0.10839 m
Explanation:
= Atmospheric pressure = 1 atm = 101325 Pa
= Total pressure at bottom of mecury = 1.2 atm
g = Acceleration due to gravity = 9.81 m/s²
h = d = Depth of mercury
= Density of mercury = 
= Density of water = 
Pressure at the bottom is of the cylinder is given by

Pressure at the bottom of mercury is

The depth of the mercury is 0.10839 m
Into molecules of
sugar and
oxygen.
The complete reaction of the photosynthesis is in fact:

and the energy of the light coming from the sun is also used to make the reaction possible.
Answer:
Explanation:
initial angular velocity, ωo = 0 rad/s
angular acceleration, α = 30.5 rad/s²
time, t = 9 s
radius, r = 0.120 m
let the velocity is v after time 9 s.
Use first equation of motion for rotational motion
ω = ωo + αt
ω = 0 + 30.5 x 9
ω = 274.5 rad/s
v = rω
v = 0.120 x 274.5
v = 32.94 m/s
While the boy is sitting on the chair it creates a force downward on the chair and therefore the chair takes it and gives off the equal amount of force. So while he is putting force downward the chair is putting the same force upward.
