distance d = 5 km = 5 x 1000 m = 5000 m
time taken = 25 minute = 25 x 60 sec = 1500 sec
average velocity V = d/t
V = 5000/1500
V = 3.33 m/s towards east
Answer:
Exerxingtransforms the chemical energy in the food you eat into Kinetic Energy.
Therefore, the answer is A. Kinetic Energy
The electricity would stop flowing through the wire and the battery would stop charging
As long as the moon orbits the Earth in the same way, the phases will be the same.
Answer:
15 nC and 10 nC
Explanation:
qA + qB = 25 nC = 25 x 10^-9 C
F = 5.4 x 10^-4 N
d = 5 cm = 0.05 m
Use the Coulomb's law

By substituting the values, we get

qA x qB = 1.5 x 10^-16 C
So, 



qA = 15nC or 10nC
So, qB = 10 nC or 15 nC
