Which of the four elements is most likely to form cations in its reactions ? A. Nh

B. Ts

C. Mc

D. Og

the dependant variable is spilled water

the independent is the heat

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.
