Answer from: vannah94

8.9 m/ $s^{2}$

Explanation:

From Newton's law of universal gravitation,

F = $\frac{GMm}{R^{2} }$ .............. 1

and from Newton's second law of motion,

F = mg ........... 2

Equating the two expression,

mg = $\frac{GMm}{R^{2} }$

g = $\frac{GM}{R^{2} }$

Given that: mass of Venus = 4.87 x $10^{24}$ Kg, radius = 6.05 x $10^{6}$ and G = 6.67 x $10^{-11}$ N $m^{2} Kg^{-2}$

Thus;

g = $\frac{6.67*10^{-11}*4.87*10^{24} }{(6.05*10^{6} )^{2} }$

= $\frac{3.24829*10^{14} }{3.66025*10^{13} }$

= 8.87450

g = 8.9 m/ $s^{2}$

the acceleration of gravity on the surface of Venus is 8.9 m/ $s^{2}$ .

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

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
