Answer : The specific heat capacity of the alloy 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of alloy = ?
= specific heat of water = 
= mass of alloy = 21.6 g
= mass of water = 50.0 g
= final temperature of system = 
= initial temperature of alloy = 
= initial temperature of water = 
Now put all the given values in the above formula, we get


Therefore, the specific heat capacity of the alloy 
Answer:
Motion
Explanation:
because when something moves its call motion
The answer is C,<span> The sum of all forces acting on the object is zero. hope that helps!!</span>
