Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
Answer:
Explanation:
Applying the Heisenberg uncertainty principle,
Δx X mΔv = h/4π
where Δx = uncertainty in measurement of position
Δv = uncertainty in measurement of velocity
m = mass of object
h = planck's constant
Here:
Δv = 0.4 A° = 4.0 x 10^-11 m
mass, m = 9.11 x 10^-31 Kg
Plugging the values,
4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)
4.0 x 10^-11 x Δ v = 5.791 x 10^-5
Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity
Answer = 1.45 x 10^6 m/s
Answers and explanation:
To answer these questions you use a periodic table.
A is In because it has 49 protons and In is element number 49.
B is 27 because Co is element number 27.
C is 73 because Ta is element number 73.
D is 49 because the number of electrons in an atoms is always equal to the number of protons.
E is 56 because the atomic number of Ba is 56.
F is 54 because 56 - 54 = 2. The charge is equal to the number of protons minus the number of electrons.
G is 66. The number of neutrons is equal to the atomic mass minus the number of protons. 115 - 49 = 66.
H is 108 because 181 - 73 = 108.
I is 32. The atomic mass of an element is equal to the amount of protons plus the amount of neutrons. So 16 + 16 = 32.
