Answer:
Pauli exclusion principle
Explanation:
Pauli's exclusion principle speaks to the quantum numbers assigned to an electron to describe it's general position and movement. Two electrons can occupy the same energy level (which is described by the first quantum number-the principal quantum number), the orbital angular momentum quantum number (represented by the second number) and magnetic quantum number. electrons that have the same value for all three numbers will have different spins. one will have positive a half while the other has negative a half. Therefore they will never have the same complement of quantum numbers
Answer:
Explanation:
Because of the following ,it is useful to select both objects as the system during collision between an electron and a hydrogen atom
1. The total momentum of the system does not change during the collision.
2.The forces the objects exert on each other are internal to the system and don't change the total momentum of the system.
3. During the time interval just before to just after the collision, external forces are negligible.
#1
Since Beth rode the Flying saucer ride which is spinning on its axis while axis is moving to and fro as well, so here Beth will experience two motions in this case
(i) Spinning motion
(ii) Rotational motion
#2
Jill and Scott both traveled for 30 min
So time of motion for both is 0.5 h as we know that 1 h = 60 min
Now from the formula of speed we know that
Speed of Jill
speed of Scott
so correct answer is
B) Scott had the faster speed since he rode at 20 k/h while Jill only traveled 10 km/h.
#3
Since we know that <em>acceleration is rate of change in velocity</em>
So here we can say that every motion where velocity changes with time then it is an accelerated motion.
Now change in velocity occurs when either the magnitude will change or its direction will change because here velocity is a vector quantity and it will change with magnitude and direction both.
so here due to oval path the direction of velocity will changes at many points and hence it will be an accelerated motion.
so correct answer is
<em>C) James was right since the car changed direction during the race.</em>
Aswer:
False, the values of the distance traveled and the displacement only coincide when the trayectorie is a straight line. Otherwise, the distance will always be greater than the offset.
Although these terms are used synonymously in other cases, they are totally different. Since the distance that a mobile travels is the equivalent of the length of its trajectory. Whereas, the displacement will be a vector magnitude.

Answer:
Olympus Mons on Mars.
Explanation:
It was discovered on Mars in 1971 and stands at a monstrous 21.9 km.
For reference, Mount Everest stands at 8.8K.
