An 11 kg salami is supported by a cord that runs to a spring scale. a second 11 kg salami is attached to a second cord which is also attached to the spring scale. the spring scale will show a reading of: a. 0 n b. 11 n c. 110 n d. 220 n

The weight of any object =

(mass) x (acceleration gravity in the place where the object is) .

Now, the acceleration of gravity on Planet Earth = 9.81 m/s²

Weight of one 11kg salami = (11 kg) x (9.81 m/s²) = about 107.9 Newtons

Weight of two 11kg salamis = (22 kg) x (9.81 m/s²) = about 215.8 Newtons

The last choice on the list, Choice-D is the choice nearest to 215.8 Newtons.  

Notes:

1). Choice-D was obtained using 10 m/s² for the acceleration of gravity on Earth.

2). Contrary to the assumptions of Drs. A. Einstein, R. Feynman, E. M. Hafner, and other great leaders and thinkers in Physics, the laws of Physics are NOT always precisely reversible, and may even become hazardous if reversibility is attempted.  To illustrate, using the current exercise:

Two 22-kg salamis, if hung from a spring scale, increase the reading of the spring scale by some 215 Newtons.  BUT ... any attempt to EAT 215 Newtons of salami, although resulting in an immediate increase in mass of 22 kg, proceeds ... inexorably and usually catastrophically ... to a DECREASE of MORE than 22 kg of mass, approximately balanced with more than 50% in each direction.  22 kg translates to 48.5 pounds of salami ... a critical mass leading to spontaneous bilateral projectile evacuation, in any language.  

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
