Force = mass × acceleration

static force = coefficient of friction × normal force 
1.70 = 0.0600 × normal force...
normal force = 1.70 ÷ 0.0600.. to obtain....

Answer: The minimum force by which player should hit the puck to move it is 0.102 N.

Explanation:

Weight of the puck = 1.70 N

This weight of the puck is the force acting normal to the surface that is:

N = 1.70 N

The coefficient of friction =\mu _f=0.0600

Frictional force = F_f=\mu _f\times N=0.0600\times 1.70 N=0.102 N

The minimum force by which player should hit the puck to move it is 0.102 N.

A salt forms in the reaction of barium with chlorine. What is the most likely formula unit of this salt?
Scrat [10]
The answer to this question would be: BaCl 2
Barium is an alkali metal with 56 atomic number. Barium located in the group 2 of the periodic table because it has 2 valence electrons. Chlorine is a nonmetal that has 1 valence electron. When react, it would need 2 chlorine for each barium as the valence electron of barium is twice the chlorine.
