Answer:
shielding of electrons
Explanation:
The addition of electrons shells results in the shielding of electrons away from the nucleus, most importantly the nuclear pull resulting from the charge.
- The nucleus pulls electrons to itself due to the net positive charge on it.
- As more electronic shell is added, the effect of the pull weakens outward.
- The inner shell experiences the nuclear pull more than the outer shell electrons.
The effect is responsible for a wide range of properties of elements.
Answer:
Explanation:
The equation for acceleration is
where vf is the final velocity and v0 is the initial velocity. Filling in:
so
a = 2.5 m/s/s
Answer: 90000 kgm/s
Explanation:
Given that,
Momentum of car = ?
Mass of car = 1,5000 kg
Velocity of car = 6 m/s
Recall that momentum is the product of mass of the moving object by its velocity
i.e Momentum = mass x velocity
Momentum = 15000kg x 6m/s
= 90000kgm/s
Thus, the momentum of the car is 90000 kgm/s
Somersaulting- for longer distances.It bends the narrow end in the direction it wants to go & takes grip with tentacles. It releases the broad end and straightens up. like this it continues. looping- for shorter distances.
Hope this helps
Answer:
C
Explanation:
The change in momentum of x has to be the opposite of the change in momentum of Y because the momentum is just transferred from one to another. But I'm still trying to figure it out how to calculate.
