Answer:
10 m/s
Explanation:
Kinetic energy= mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=mv²
v²= (use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s
Answer: 118 elements
Step-by-step explanation:
In the periodic table, the elements are sorted by atomic number. Therefore, as the list is sorted, there are 118 elements in total contained for the science periodic table.
