To solve this problem we will apply the concepts related to the balance of forces. In this case the force caused by the weight and the buoyancy force on the Fluid. Both are forces that start from Newton's second law and can be expressed as

Weight

F_W = mg

Here,

m = mass

g = Gravity

Buoyant Force

F_B = \rho_{fluid}V_{pin}g

Here

\rho_{fluid} = Density of Fluid

V_{pin}=Volume

g = Gravity

By equilibrium we have that

F_W = F_B

mg=\rho_{fluid}V_{pin}g

m=\rho_{fluid}V_{pin}

m=\rho_{fluid}(\frac{4}{3} \pi r^3 )

Replacing,

m=(1.1*10^3) [(4/3)\pi(0.11)^3]

m =6.132 Kg

Now the Weight of the balls would be

F = mg

F = 6.132 (9.8)

F = 60.0936N

Therefore the  heaviest bowling ball that will float in this fluid is 60.0936N

The length of time over which the conditions are measured

Explanation:

Weather captures the daily atmospheric conditions over a short duration hence it is short-term. Climate is the average of weather and covers a longer duration hence long-term. Therefore, what differentiatea these two is the length of time over which the conditions are measured.

Teams red and blue are having a tug-of-war. According to Newton's third law, the force with which the red team pulls on the blue

There are a few reasons that one teams could win. It depends if the on of the  teams has a better grip on the rope or not or maybe one off the teams has more friction between the ground and there shoes. So really it no matter what one of the teams will win.

An insulated rigid tank contains 3 kg of H2O in the form of a saturated mixture of liquid and vapor at a pressure of 150 kPa and
Andre45 [30]

Answer:

change in entropy is 1.44 kJ/ K

Explanation:

from steam tables

At 150 kPa

specific volume

Vf = 0.001053 m^3/kg

vg = 1.1594 m^3/kg

specific entropy values are

Sf = 1.4337 kJ/kg K

Sfg = 5.789 kJ/kg

initial specific volume is calculated as

v_1 = vf + x(vg - vf)

      = 0.001053 + 0.25(1.1594 - 0.001053)

v_1 = 0.20964  m^3/kg

s_1 = Sf + x(Sfg)

     = 1.4337 + 0.25 \times 5.7894 = 2.88 kJ/kg K

FROM STEAM Table

at 200 kPa

specific volume

Vf = 0.001061 m^3/kg

vg = 0.88578 m^3/kg

specific entropy values are

Sf = 1.5302 kJ/kg K

Sfg = 5.5698 kJ/kg

constant volume  sov_1 -  v_2  = 0.29064 m^3/kg

v_2 = v_1 = vf + x(vg - vf)

       =0.29064 = x_2(0.88578 - 0.001061)

x_2 = 0.327

s_2 = 1.5302 + 0.32 \times 5.5968 = 3.36035 kJ/kg K

Change in entropy \Delta s = m(s_2 - s_1)

              =3( 3.36035 - 2.88) =  1.44 kJ/kg

Which is a scalar quantity displacement distance force acceleration​
cestrela7 [59]

A scalar is a quantity that is fully described by a magnitude only. It is described by just a single number. Some examples of scalar quantities include speed, volume, mass, temperature, power, energy, and time. A vector is a quantity that has both a magnitude and a direction.

I hope this helps you.
