The pressure exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation p = ρgh, where g is the gravitational acceleration.
p = ρghρ = 1000 kg/m3g = 9.81 m/s2convert mm h20 to Pa700 mm H20 ( 9.81 pa / 1 mm h2o)= 6867 Pa
6867 Pa = (1000 kg/m3)(9.81 m/s2)hh = 0.7 mh = 700 mm

Answer:

$m_2 = 23 kg$

Explanation:

As we know that the tension in two strings are

$T_2 = 111 N$

$T_4 = 222 N$

now we have

$F_{net} = ma$

so we can say

$(m_1 + m_2)a = T_2$

$(12 + m_2)a = 111$

also we have

$(m_1 + m_2 + m_3 + m_4) a = T_4$

$(12 + m_2 + 15 + 20) a = 222$

now divide two equations

$\frac{222}{111} = \frac{47 + m_2}{12 + m_2}$

$2m_2 + 24 = 47 + m_2$

$m_2 = 23 kg$

Gravity on the surface of the moon is only 1/6 as strong as gravity on the Earth. What is the weight of a 19 kg object on the Ea

Dahasolnce [82]

The weight of anything in any place is

(mass of the thing) x (acceleration of gravity in that place).

-- On Earth, the acceleration of gravity is about 9.807 m/s²

Weight of 19 kg of mass is (19 kg) x (9.807 m/s²) = <em>186.3 newtons</em>

-- On the Moon, the acceleration of gravity is about 1.623 m/s²

Weight of the same 19 kg of mass is (19 kg) x (1.623 m/s²) = <em>30.8 newtons</em>
