Answer:
the cell which does not contain acid is called dry cell
Explanation:
it is made in a zinc container. if the dry cell is not used for a long time, it stops working due to local action.
<h3>thank you :)</h3>
Answer:
Removing Energy: Removing energy will cause the particles in a liquid to begin locking into place. A. Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas.

Answer: The smallest effort = 300N
Explanation:
Using one of the condition for the attainment of equilibrium:
Clockwise moment = anticlockwise moments
900 × 1 = 3 × M
Where M = the weight of the strong man
3M = 900
M = 900/3 = 300N
Therefore, 300N is the smallest effort that the strongman can use to lift the goat
We begin by noting that the angle of incidence is the one that's taken with respect to the normal to the surface in question. In this case the angle of incidence is 30. The material is Flint Glass according to the original question. The refractive indez of air n1=1, the refractive index of red in flint glass is nred=1.57, finally for violet in the glass medium is nviolet=1.60. Snell's Law dictates:
![n_1sin(\theta_1)=n_2sin(\theta_2)](https://tex.z-dn.net/?f=n_1sin%28%5Ctheta_1%29%3Dn_2sin%28%5Ctheta_2%29)
Where
![\theta_2](https://tex.z-dn.net/?f=%5Ctheta_2)
differs for each wavelenght, that means violet and red will have different refractive indices in the glass.
In the second figure provided details are given on which are the angles in question,
![\Delta x](https://tex.z-dn.net/?f=%5CDelta%20x%20)
is the distance between both rays.
![\theta_{2red}=Asin(\frac{sin(30)}{1.57})\approx 18.5705](https://tex.z-dn.net/?f=%5Ctheta_%7B2red%7D%3DAsin%28%5Cfrac%7Bsin%2830%29%7D%7B1.57%7D%29%5Capprox%2018.5705)
![\theta_{2violet}=Asin(\frac{sin(30)}{1.60})\approx 18.21](https://tex.z-dn.net/?f=%5Ctheta_%7B2violet%7D%3DAsin%28%5Cfrac%7Bsin%2830%29%7D%7B1.60%7D%29%5Capprox%2018.21)
At what distance d from the incidence normal will the beams land at the bottom?
For violet we have:
![d_{violet}=h.tan(\theta_{2violet})\approx 0.0132m](https://tex.z-dn.net/?f=d_%7Bviolet%7D%3Dh.tan%28%5Ctheta_%7B2violet%7D%29%5Capprox%200.0132m)
For red we have:
![d_{red}=h.tan(\theta_{2red})\approx 0.0134m](https://tex.z-dn.net/?f=d_%7Bred%7D%3Dh.tan%28%5Ctheta_%7B2red%7D%29%5Capprox%200.0134m)
We finally have:
