<span>We can draw a free body diagram for one of the boxes.
There are two forces acting on the box.
The downward force is the force of gravity which is 50 N.
The upward force is the force from the tension in the rope.
Since the box is suspended, it is not accelerating.
Therefore, the net force must be zero.
Therefore the tension in the rope must be 50 N.</span>
Specific heat of a substance can be calculated using the equation q=mst, where “q” is heat applied to the system, “m” is the mass of the substance, “s” is the specific heat, and “t” is the change in temperature. In this case,
q=mst
(1495 J)=(339 g)(s)(+11 degrees C)
s=0.401 J/g•degrees C.
The specific heat of this substance is 0.401 J/g•degrees C). However, the problem is asking for the heat capacity of the metal, which is defined as C=ms using the same definitions as above. In this case, the heat capacity of the metal works out to be 135.91 J/g.
Hope this helps!
<span>2. mass of both objects doubled?
Hope it helped!</span>
C) When both objects have the same temperature.
