Answer:

<h3>The answer is 41.05 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual density = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

So we have

p(\%) =  \frac{0.39}{0.95}  \times 100 \\  = 41.0526315...

We have the final answer as

<h3>41.05 %</h3>

Hope this helps you

A cylindrical grain has a base radius of 5m. the surface area is 1099m^2. What is the height of the bin to the nearest metre?
Inessa05 [86]

The height of the bin is 29.9m.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.

The radius of the cylinder, r = 5m

Surface area = 1099 m²

∴ A = 2πrh + 2πr²

  h = \frac{A- 2\pi r^2}{2\pi r}

  h = \frac{1099- 2 (3.141) 5^2}{2 (3.141) 5}

  h = \frac{1099- 157.05}{31.41}

  h = \frac{941.95}{31.41}

  h = 29.9 m

Therefore, the height of the bin is 29.9m.

How do you find the pressure in a container if you don't have the temperature? 
BARSIC [14]
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.


For adiabatic process,

PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.

where gamma = Cp
                          ------
                           Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.

Value of Gamma will be given in question.
Hope this helps!
