Well, it happens a few weeks ahead, then for a total of 3 hours and 40 minutes.
C is true, and just one of those has as much mass as about 1,840 electrons.
Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
