Time = Distance / speed
Time = 2.5 km / 23 km/h
= 0.1087 hours 1 hour = 60 minutes
= 0.1087 * 60 minutes
= 6.522 minutes.
The atomic number tells you the number of protons in an atom. This value never changes because the number of protons in the nucleus always remains constant. The mass number tells you the number of protons and neutrons (or nucleons) together: protons + neutrons = mass number. Since the number of neutrons in the nucleus varies, you can have different amounts of neutrons in the same type of atom. These varied types are called isotopes.
Hope this helps.

Answer:
The acceleration of gravity on the Moon is only one-sixth of that on Earth. If we hit a baseball on the moon with the same effort(and at the speed and angle)that we would on earth, the ball would land 6 times as far. The ball on the moon will cover 6 times more distance than Earth.
Explanation:
Speed=distance travelled/Time required speed
Speed=d/t
Acceleration of gravity on earth=9.8 m/s^2
Acceleration of gravity on Moon=1.62 m/s^2
So the maximum height of ball will be the ration of these both gravity.
