The answer is -1, because protons are positive charges and electrons are negative charges. If you subtract them you would get you answer if -1
The free-body diagram of your question is; 2 downward forces (253 kg mass of barbell & 133 kg body mass of Kurlovich) acting together on a point supported by 2 upward forces as normal forces exerted by Kurlovich's feet.
Solving the normal forces exerted by 2 feet :
Summation of Forces Vertical = 0
2 Dowwnard Forces = 2 Upward Forces (2F)
253 + 133 = 2F
2F = 386 Kgs
F = 386 / 2
F = 193 Kgs (Normal Force Exerted by Each Foot)
penguins! so momentum is based on mass and velocity, the advantages is that they have stored mass in the form of like fats to keep them warm however they are built to slide basically so that there is less friction when they travel so sideways their bullet like shape helps increase velocity so they have both mass and considerable velocity!
