The acceleration of each object will be 2.31 m/s².While the direction for mass 1 is down, mass 2 is left and mass 3 is up.

<h3>What is tension force?</h3>

The tension force is described as the force transferred through a rope, string, or wire as it is pulled by opposing forces.

The tension force is applied along the whole length of the wire, pulling energy equally on both ends.

From Newton's second law, the net force is equal to the product of the mass and acceleration. Forces and tension acting upward are positive while the downward is taken as negative.

Foer mass m₁ only vertical force is considered.

\rm \sum F_y=ma_y \\\\ + T_{12}-m_1g =-m_1a \\\\ -T_{12}+39.2 \ N=(4.00 \ kg )a

For mass m₂ both horizontal and verticle force is considered;

\rm  \sum F_x=ma_x \\\\ -T_{12}+f+T_{23}\\\\ -T_{12}+\mu_kN+T_{23} \\\\ T_{12}-0.350(9.80 \ N)-T_{23}=(1.00 \ kg)a

\rm \sum F_y =ma_y \\\\ N-m_2g=0

Foer mass m₃ only vertical force is considered.

\rm \sum F_y=ma_y \\\\ T{23}-m_2g=+m_3a \\\\ T_{23}-19.6 \ N=(2.00 \ kg)a

Adding  all the obtained forces we get;

\rm +39.2 \ N-3.43 \ N-19.6 N=(7.00 \kg) a\\\\ a=2.31 \ m/s^2

Hence, the acceleration of each object will be 2.31 m/s².While the direction for mass 1 is down, mass 2 is left and mass 3 is up.

Suppose a scoentist was able to construct a barometer with a liquid being denser than mercury , then how high would the liquid r
ki77a [65]

Answer:

the liquid has less height than the mercury

      h_{ liquid} = \frac{\rho_{Hg} }{\rho_{liqid}}  \  h_{Hg}

Explanation:

The pressure as a function of the height is given by

        P = ρ g h

where ρ is the density of the liquid, g the acceleration of gravity and h the height reached by the column of the liquid

In that case they say that the pressure is the standard one that is P = 1.01 10⁵ Pa = 760 mmHg

The first way to give the pressure is in SI units and the second way is the height that the mercury column reaches

In the case of building a barometer with a liquid that has a density greater than that of mercury

            ρ_liquid > ρ_Hg

             

the pressure

              P =ρ_lquid g h_liquid

if we have the same pressure

            ρ_{Hg} g h_{Hg} = ρ_{liquid}  g h_{liquid}

            h_{ liquid} = \frac{\rho_{Hg} }{\rho_{liqid}}  \  h_{Hg}

therefore the liquid has less height than the mercury
