Atrough is filled with a liquid of density 865 kg/m3. the ends of the trough are equilateral triangles with sides 10 m long and vertex at the bottom. find the hydrostatic force on one end of the trough. (use 9.8 m/s2 for the acceleration due to gravity.)

Explanation:

Since each side of the triangular end is of equilateral triangle with side length a = 10 m

so height of the triangle h = a sin60

h = 10sin60 = 8.66 m

now we will take a small strip of width L and thickness dy at a depth of y from top

so here width L is given as

now the force on this small strip is given as

now the total force on the triangular part

now the limits of y is from y = 0 to y = 8.66 m

so we have

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

it has to be b, about 97 percent.
