Answer:
It covers distance of 9.15 football fields in the said time.
Explanation:
We know that
Thus distance covered in blinking of eye =
Thus no of football fields=
<span>The
answer is B. When the system absorbs energy, the molecules gain more kinetic energy
and hence start to move faster. Doubling the size of the system also gives
more room for the molecules to move randomly around
the system <span>before colliding with other molecules
hence increasing their motion. </span></span>
Answer:
Explained below:
