By definition, we have that the number of neutrons is given by:
# neutrons = atomic mass - # protons
We know that the atomic mass is equal to 84.
We know the atomic number of Krypton is equal to 36. This means that the Krypton has 36 protons and 36 electrons.
Therefore, substituting values we have:
# neutrons = 84 - 36
# neutrons = 48
Answer:
The Krypton has 48 neutrons
Answer:
A
Explanation:
More potential energy equals more kinetic
Answer:
Jupiter's gravitational acceleration is 24.8 m/s^2
Explanation:
Recall that the weight under the influence of a gravitational acceleration G is defined as:
Weight = m * G
Then, in our case we have
372 N = 15 kg * G
G = 372/15 m/s^2
G = 24.8 m/s^2
Answer: Its in explanation.
Explanation:
Because the electroscope is made from conducting material, some of its electrons move up to the top of the electroscope to be near the charged rod when the rod is held close.
