Answer:
Statement 1) False
Statement 2) False
Statement 3) True
Explanation:
The uncertainty principle states that " in a physical system certain quantities cannot be measured with random precision no matter whatever the least count of the instrument is" or we can say while measuring simultaneously the position and momentum of a particle the error involved is
![P\cdot\delta x\geq \frac{h}{4\pi }](https://tex.z-dn.net/?f=P%5Ccdot%5Cdelta%20x%5Cgeq%20%5Cfrac%7Bh%7D%7B4%5Cpi%20%7D)
Thus if we measure x component of momentum of a particle with 100% precision we cannot measure it's position 100% accurately as the error will be always there.
Statement 1 is false since measurement of x and y positions has no relation to uncertainty.
Statement 2 is false as both the momentum components can be measured with 100% precision.
Statement 3 is true as as demanded by uncertainty principle since they are along same co-ordinates.
The explanatory variable is placed on the x-axis and the response variable is placed on the y-axis.

Answer:
a periscope use total internal reflection to allow us to see things
the reflection happens at 45°
Explanation:
<span>The question says, what drives surface current. The correct option is A, that is wind. There are two different current system in the ocean, they are deep circulation and surface circulation. Surface current is majorly driven by the wind. The wind is capable of moving the top 400 meters of the ocean, thereby creating ocean surface current. The pattern of the surface current is determined by the direction of the wind, forces from the earth rotation and the position of the landform that interact with the current.</span>
