Answer:
Explanation:
Let the normal force of the wall on the ladder be N2 and the normal force of the ground on the ladder be N1.
Horizontal forces:
[1]
Vertical forces:
[2]
Substitute [2] into [1]:
![N_2 = (u1)*[m*g - (u2)(N_2)]](https://tex.z-dn.net/?f=N_2%20%3D%20%28u1%29%2A%5Bm%2Ag%20-%20%28u2%29%28N_2%29%5D)
![N_2= \frac{(u1)m*g}{[1 + (u1)(u2)]}](https://tex.z-dn.net/?f=N_2%3D%20%5Cfrac%7B%28u1%29m%2Ag%7D%7B%5B1%20%2B%20%28u1%29%28u2%29%5D%7D)
[3]
Torques about the point where the ladder meets the ground:
![[1 + (u1)(u2) - 2(u2)(u1)]/2 [1 + (u1)(u2)]= [(u1)/[1 + (u1)(u2)]]cot\alpha](https://tex.z-dn.net/?f=%5B1%20%2B%20%28u1%29%28u2%29%20-%202%28u2%29%28u1%29%5D%2F2%20%5B1%20%2B%20%28u1%29%28u2%29%5D%3D%20%5B%28u1%29%2F%5B1%20%2B%20%28u1%29%28u2%29%5D%5Dcot%5Calpha)
tanα = 
Answer:
1. matter
2. kilograms
3. same
4. gravitational
5. gravity
6. space
7. weightlessness
8. Newton
9. weight
10. more
I HOPE THESE ARE CORRECT AND IT HELPS
Answer:
it becomes a gas
Explanation:
the matter expands, turning into steam, a gas.
Explanation:
Warm,tropical cumulus cloud more likely to produce precipitation because they have high liquid content, strong and consistent updraft, these clouds are very thick. Moreover, they have large range of cloud droplet sizes. Whereas, stratus cloud have somewhat opposite characteristics, hence tropical cumulus clouds produce more precipitate.
