What type of particles are represented by the crosses (X)(X)?

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

answer: i dont know the answer but this might

explanation:

l

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
