It tells us the number of protons that are present in the nucleus, the positively charged region of that atom.
They travel like waves. Just throw rock at lake you will see wave. When it bumps to barrier barrier reflects some part of it . Not like a line lika a wave
Answer:
17.82J
Explanation:
Kinetic energy = 1/2 mv^2
Given
Mass M = 0.45kg
Velocity v = 8.9m/s
Therefore,
K.E. = 1/2 x 0.45 x (8.9)^2
= 1/2 x 0.45 x (8.9 x 8.9)
= 1/2 x 0.45 x 79.21
Multiply through
= 35.6445/2
= 17.82J
The kinetic energy of the ball is 17.82J
Answer:
15.88°C I am not 100% sure this is right but I am 98% sure this IS right
Angstrom = 10^-10 m
for nucleus size are used fermi (femtometer 10^-15 m )
