<span>I believe the answer is: Dynamic lookup
When we use dynamic lookup cache, the cache would be updated everytime we insert a row or update our table. This would make the power cache to create memory cache based on each partitions and transform them into some sort of hierarchy.</span>

pentagon [3]

Answer:

The collision occurs at a height of 1/3 of the total height of cliff.

Explanation:

The situation is represented in the attached figure:

For the stone dropped from top of cliff we have

Initial velocity of drop= 0 m/s.

Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as

$v_{f}=u_{i}+gt\\\\2v=0+gt\\\\\therefore t=\frac{2v}{g}$

Thus the distance it covers in this time can be calculated using third equation of kinematics as

$v_{f}^{2}=v_{i}^{2}+2gh\\\\(2v)^{2}=2gh_{1}\\\\\therefore h_{1}=\frac{2v^{2}}{g}$

For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as

$v=v_{i}-gt\\\\\therefore v_{i}=v+gt\\\\v_{i}=v+g\times \frac{2v}{g}\\\\\therefore v_{i}=3v$

The height over which it changes it's velocity from '3v' to 'v' can be again obtained from third equation of kinematics as

$v^{2}=(3v)^{2}-2gh_{2}\\\\v^{2}=9v^{2}-2gh_{2}\\\\\therefore h_{2}=\frac{4v^{2}}{g}$

$\therefore h_{2}=2h_{1}$

Thus the collision occurs at at a fraction of 1/3 of height.

The system with the highest level of government control is communism. In theory, a communist economy is one in which the government owns all or most enterprises. Central planning by the government dictates which goods or services are produced, how they are produced, and who will receive them.

If a radiographer receives an exposure of 0.05 millisievert (msv) at a distance of 1.5 feet from the tube of a portable x-ray un

otez555 [7]

Answer:

0.003125 msv

Explanation:

$I_1$ = Initial Exposure = 0.05 msv

$I_2$ = Final Exposure

$D_1$ = Initial distance = 1.5 ft

$D_2$ = Final distance = 6 ft

Exposure is inversely related to the distance squared (inverse square law)

$I\propto \dfrac{1}{D}$

So,

$\dfrac{I_1}{I_2}=\dfrac{D_2^2}{D_1^2}\\\Rightarrow I_2=\dfrac{I_1D_1^2}{D_2^2}\\\Rightarrow I_2=\dfrac{0.05\times 1.5^2}{6^2}\\\Rightarrow I_2=0.003125\ msv$

The exposure at the given distance is 0.003125 msv
