1. Take a breaker
2. Put a sieve on it
3. Pour the mixture and shake the sieve gently
4. Wait for the flour to fall. After the flour falls pour the rice from the sieve into other beaker then do experiment again for fair testing(optional)
Answer:
![2.8 m/s^2](https://tex.z-dn.net/?f=2.8%20m%2Fs%5E2)
Explanation:
We are given that
Initial speed,u=8 m/s
Final speed,v=6 m/s
Distance,s=5 m
We have to find the magnitude of her acceleration as she shows.
We know that
![v^2-u^2=2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as)
Using the formula
![(6)^2-(8)^2=2a(5)=10a](https://tex.z-dn.net/?f=%286%29%5E2-%288%29%5E2%3D2a%285%29%3D10a)
![-28=10a](https://tex.z-dn.net/?f=-28%3D10a)
![a=\frac{-28}{10}=-2.8 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B-28%7D%7B10%7D%3D-2.8%20m%2Fs%5E2)
Magnitude of acceleration=![\mid a\mid=2.8 m/s^2](https://tex.z-dn.net/?f=%5Cmid%20a%5Cmid%3D2.8%20m%2Fs%5E2)
I believe the correct answer from the choices listed above is option D. <span>The process of bringing the solvent to boiling, evaporating it all away, and leaving the solute behind, is known as evaporation. Hope this answers the question. Have a nice day.</span>
Answer:
Explanation:
The momentum of the 25 kg mass is
![p=mv](https://tex.z-dn.net/?f=p%3Dmv)
![p=25kg*3m/s= 75kg*m/s](https://tex.z-dn.net/?f=p%3D25kg%2A3m%2Fs%3D%2075kg%2Am%2Fs)
If this whole momentum of the object is transferred to the 5.0 kg object then according to the law of conservation of momentum, the momentum of the 25.0 kg object must be transferred to the 5.0 kg object:
![75kg*m/s = 5.0kg*v](https://tex.z-dn.net/?f=75kg%2Am%2Fs%20%3D%205.0kg%2Av)
![v=\dfrac{75}{5}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B75%7D%7B5%7D)
![\boxed{v=15m/s}](https://tex.z-dn.net/?f=%5Cboxed%7Bv%3D15m%2Fs%7D)
To stop the movement of Earth's tiny the inner core of the planet would have to lose loads of heat so it turns solid, then it would stop moving but if this happens we would lose lots of magnetic shield generated by the liquid metal near the core of the planet which protects from radiation the sun gives us.
Hope that helps!
