<h3>
Answer:</h3>
B. The object moves some distance
<h3>
Explanation:</h3>
- Work is the product of force and distance.
- Work is done on an object when a force is applied on the object making it move some distance.
- For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.
- Applying a force on an object without making it move some distance then there is no work done.
- Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.

They are indeed placed from the far left hand side of the periodic table in almost the same column. If you step around the table between left to right, the movement of electrons rises by one. When you progress down the line, the number of power increases by the one.
Answer: 2.02 J/g°C
Explanation:
To find the heat capacity, we have to manipulate the equation for heat.
q=mCΔT becomes C=q/(mΔT) to find heat capacity. Since we are given our values, we can plug in to find C.
*Please ignore the capital A in front of the °C. In order to have ° in the equaiton, the A pops up.
