Answer:
It will reduce by 9 times and become 400 N.
I think that the velocity is 0.245m per second
Answer:
60N
Explanation:
force = mass * acceleration
force = 12 * 5
force =60N
Answer:
Biomedical engineering
Explanation:
this is because plant sees are important
Answer: The correct answer is : From the period-luminosity relation for Cepheids, he was able to determine the distance to Andromeda and show that it was far outside the Milky Way Galaxy.
Explanation: Hubble's law says that the recession velocity of a galaxy is directly proportional to its distance from us. Hubble measured the distance to the Andromeda galaxy by applying the period-luminosity relationship to Cepheid.
