To find the height a block can be raised using 490 J of work, we can use the formula for work: ( W = F \cdot d ), where ( W ) is work, ( F ) is force (weight of the block), and ( d ) is the distance (height raised). Rearranging the formula gives ( d = \frac{W}{F} ). Substituting the values, we have ( d = \frac{490 , \text{J}}{7 , \text{N}} = 70 , \text{m} ). Therefore, the block can be raised 70 meters.
