Length of the sheet is given as

L = \frac{200}{3} yards = 6096 cm

width of the sheet is given as

w = 12 inches = 30.48 cm

now let say its thickness is "t"

so the volume of the sheet is given as

V = L*w*t

V = 6096*30.48* t

V = 185806.08*t cm^3

mass of the sheet is given as

m = 0.83 kg = 830 gram

now we have

density = \frac{mass}{volume}

2.70 = \frac{830}{185806.08*t}

by solving above we have

t = 1.65 * 10^{-3} cm

so the thickness of sheet will be above

Explain the process of <br>anomalous expansion of water​
Kay [80]

The anomalous expansion of water refers to the fact that water, unlike most substances, expands when it freezes. The density of water increases as temperature decreases but reaches a maximum at 4° C then begins to expand.

When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

\There was a truck pulling a horse trailer. If the horse trailer weighted 150kg, went 250 miles, and the trucked used 20N to mak
mestny [16]

Answer:

a  = 0.13m/s²

Explanation:

Given parameters:

Weight of horse trailer  = 150kg

Distance covered  = 250miles

Force applied on trailer  = 20N

Unknown:

Acceleration of trailer = ?

Solution:

According to newton's second law of motion,"the acceleration of a body is directly proportional to the force on it and inversely proportional to the mass" .

          Mathematically;

                                    F  = m x a

 where f is the force

             m is the mass

               a is the acceleration

Input the parameters and solve;

                  20  = 150 x a

                      a  = 0.13m/s²
