The isotope notation for the isotope of iodine that has 67 neutrons is
<h3>Meaning of Isotope</h3>
Isotopes can be defined as an element members that all have the same number of protons but different numbers of neutrons.
Isotopes possess the same number of protons in a nucleus and this is what defines the element's atomic number.
In conclusion, The isotope notation for the isotope of iodine that has 67 neutrons is

Answer:
2966 m
Explanation:
Assuming g = 9.8 m/s and ignoring air resistance,
the coin reaches 60 m/s in t = v/a = 60/9.8 = 6.12 s
h = 3150 - ½(9.8)6.12² = 2,966.326
Answer:
a) ball K <K₀, b) the speed of the ball after the collision, c) can K> 0
d) can moves in the same direction as the ball
Explanation:
a) the kinetic energy is given by
K = ½ M v²
in this case before the collision the kinetic energy of the ball is
K₀ = ½ M v₀²
After the collision the aluminum can has a certain speed, therefore the kinetic energy of the ball must decrease, the velocity of the ball after the collision is
v <v₀
therefore the kinetic energy is
K = ½ m v²
in consecuense
K <K₀
b) an evidence of this fact is to measure the speed of the ball before the collision and the speed of the ball after the collision,
c) In the case of the aluminum can, the initial kinetic energy is ero, because it is stopped
K₀ = 0
after the collision a part of the cal momentum of the ball is transferred to the can, therefore its velocity is different from zero
K = ½ m v_can²
K> 0
d) the clearest evidence of this fact is that the can moves in the same direction as the ball
