Answer:
Every action has an equal and opposite reaction. If the student doesn't push, nothing moves, is one student pushes, both move which is an example of newtons third law.
Explanation:
Answer:
Elements that are made from only one type of atom
Explanation:
As we know that force F makes an angle of 60 degree with X axis
so the X component is given as
![cos60 = \frac{F_x}{F}](https://tex.z-dn.net/?f=cos60%20%3D%20%5Cfrac%7BF_x%7D%7BF%7D)
now we have
![F_x = F cos60](https://tex.z-dn.net/?f=F_x%20%3D%20F%20cos60)
![F_x = 0.50 F](https://tex.z-dn.net/?f=F_x%20%3D%200.50%20F)
Similarly we know that force F makes an angle of 45 degree with Y axis
so the X component is given as
![cos45 = \frac{F_y}{F}](https://tex.z-dn.net/?f=cos45%20%3D%20%5Cfrac%7BF_y%7D%7BF%7D)
now we have
![F_y = F cos45](https://tex.z-dn.net/?f=F_y%20%3D%20F%20cos45)
![F_y = 0.707 F](https://tex.z-dn.net/?f=F_y%20%3D%200.707%20F)
Now for the component along z axis we know that
![F_x^2 + F_y^2 + F_z^2 = F^2](https://tex.z-dn.net/?f=F_x%5E2%20%2B%20F_y%5E2%20%2B%20F_z%5E2%20%3D%20F%5E2)
now plug in all components
![(0.707 F)^2 + (0.50 F)^2 + F_z^2 = F^2](https://tex.z-dn.net/?f=%280.707%20F%29%5E2%20%2B%20%280.50%20F%29%5E2%20%2B%20F_z%5E2%20%3D%20F%5E2)
![0.5 F^2 + 0.25 F^2 + F_z^2 = F^2](https://tex.z-dn.net/?f=0.5%20F%5E2%20%2B%200.25%20F%5E2%20%2B%20F_z%5E2%20%3D%20F%5E2)
![F_z^2 = F^2(1 - 0.75)](https://tex.z-dn.net/?f=F_z%5E2%20%3D%20F%5E2%281%20-%200.75%29)
![F_z^2 = 0.25 F^2](https://tex.z-dn.net/?f=F_z%5E2%20%3D%200.25%20F%5E2)
![F_z = 0.5 F](https://tex.z-dn.net/?f=F_z%20%3D%200.5%20F)
