The data which is accurate means it can't be changed further is called accurate data. while, The data which is changed again and again is called reproducible data. Reproducible data is one component of the precision of a measurement or test method and accurate data is one of the components of data quality.
When calcium oxide reacts with water, then it combines with water and forms calcium hydroxide.
CaO + H2O → Ca(OH)2
Calcium oxide + Water → Calcium hydroxide
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base

Answer:
v = 2.94 m/s
Explanation:
Given that,
Mass of anvil, m = 15 kg
The gravitational potential energy relative to the floor, P = 65 J
We need to find the speed just before it hits the floor when the Anvil is released. Let it is v.
We can use the conservation of energy.
![\dfrac{1}{2}mv^2=mgh\\\\65=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{65\times 2}{15}} \\\\v=2.94\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%3Dmgh%5C%5C%5C%5C65%3D%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%5C%5C%5C%5Cv%3D%5Csqrt%7B%5Cdfrac%7B65%5Ctimes%202%7D%7B15%7D%7D%20%5C%5C%5C%5Cv%3D2.94%5C%20m%2Fs)
So, the required speed is 2.94 m/s.
The displacement distance from my house to school never changes but the time it takes varies due to traffic and it's effects on my vehicle's speed and position in line at stop lights.
Answer:
Here,
Initial velocity(u)=0 m/s
acceleration(a)=1.5m/s
time(t)=0.5s
Now,
distance covered(s)=ut+(1/2)at^2
=0*0.5+(1/2)*1.5*0.5*0.5
=0+(1/2)*0.375
=0+0.1875
=0.1875(nearly 0.19)
Hence,0.19 is correct answer.
