Answer from: jfrey7621

The tension in the string is 128.625 N.

Explanation:

Given that,

Side length = 0.25 m

Density of balsa wood = 160 kg/m³

We need to calculate the volume of the cube

V= l^3

V=(0.25)^3

$V=0.015625\ m^3$

We need to calculate the mass

Using formula of density

$\rho=\dfrac{m}{V}$

$m=\rho\times V$

Put the value in to the formula

$m=160 \times0.015625$

$m=2.5\ kg$

We need to calculate the weight

W = mg

$W=2.5\times9.8$

$W=24.5\ N$

We need to calculate the buoyant force

$F=V\rho g$

Where, V = volume

$\rho$ = gravity

g = acceleration due to gravity

Put the value into the formula

$F =0.015625\times1000\times9.8$

$F=153.125\ N$

We need to calculate the tension in the string

T=F-mg

T=153.125-24.5

$T=128.625\ N$

Hence, The tension in the string is 128.625 N.

Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colourless liquid organic compound with the chemical formula ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called glacial acetic acid. vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. it is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7 3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366 chemblchembl539 chemspider171 drugbankdb03166 echa infocard100.000.528ec number200-580-7e numbere260 (preservatives)gmelin reference1380iuphar/bps1058keggd00010 meshacetic+acidpubchem cid176rtecs numberaf1225000uniiq40q9n063p un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4) key: qtbsbxvteameqo-uhfffaoysa-n smilescc(o)=o
