Answer:
a North and South Pole :)
Explanation:
Answer:’B’
Explanation:Since, the nucleus is in the middle and it carries protons which carry positive charge and neutrons which carry no charge.
Answer:
Explanation:
Use the following equation:
and solve for F:
and filling in:
![F=\frac{.0600}{1500}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B.0600%7D%7B1500%7D)
F = 4.0 ×
N
Answer:
that's your 1st cousin which is your mom or dad's sibling's child sooo when you're that close and that related i would say that that would be the reason why.

Answer:48.2 Joules
Explanation:
Given
two masses of 0.2 kg and 0.4 kg collide with each other
after collision 0.2 kg deflect 30 north of east and 0.4 kg deflects 53.1 south of east
Velocity of 0.2 kg mass is
![v_{0.2}=12\cos (30)\hat{i}+12\sin (30)\hat{j}](https://tex.z-dn.net/?f=v_%7B0.2%7D%3D12%5Ccos%20%2830%29%5Chat%7Bi%7D%2B12%5Csin%20%2830%29%5Chat%7Bj%7D)
![|v_{0.2}|=11.99 m/s\approx 12 m/s](https://tex.z-dn.net/?f=%7Cv_%7B0.2%7D%7C%3D11.99%20m%2Fs%5Capprox%2012%20m%2Fs)
Velocity of 0.4 kg mass
![v_{0.4}=13\cos (53.1)\hat{i}-12\sin (53.1)\hat{j}](https://tex.z-dn.net/?f=v_%7B0.4%7D%3D13%5Ccos%20%2853.1%29%5Chat%7Bi%7D-12%5Csin%20%2853.1%29%5Chat%7Bj%7D)
![|v_{0.4}|=12.99 m/s\approx 13 m/s](https://tex.z-dn.net/?f=%7Cv_%7B0.4%7D%7C%3D12.99%20m%2Fs%5Capprox%2013%20m%2Fs)
Thus total Kinetic energy ![=\frac{0.2\times 12^2}{2}+\frac{0.4\times 13^2}{2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B0.2%5Ctimes%2012%5E2%7D%7B2%7D%2B%5Cfrac%7B0.4%5Ctimes%2013%5E2%7D%7B2%7D)
Kinetic energy=48.2 J
