Answer:
a. The apparent depth of the object is less than the real depth.
Explanation:
When we observe for any object lying at the bottom of the pool from the edge of the pool then we are actually viewing an object from an optically rarer medium into an optically denser medium.
The schematic shows the apparent view of the object due to the bending of the rays coming form the object to our eyes.
The rays when coming from a denser medium to a rarer medium they bend away from the normal of the interface.

Check the explanation
Explanation:
Each number in the wheel spans 360/12 = 30 degree
Therefore 41.91 degree corresponds to the number 29 on the wheel when the wheel spins clockwise.
True because when the independent answer changes, then the dependent variable, which relies on the independent variable, changes.
Answer:
A) Motion-sensor activated cameras
Explanation:
Motion sensor activated cameras are the ones which actuate a trigger when any sort of motion is detected by them. They can play alarming sound, send e-mails and zoom the frame of motion as a response to the detected motion.
Motion sensor cameras can be of two types:
1. Fixed view camera
2. Rotating view camera
Fixed view cameras are in fixed position and they always point in the same direction for the view while the rotating cameras are the ones which can change their direction of view.
For a small and high security space we can use the fixed type camera so that we do not miss any suspicious movements. For wide areas and distant vision we use rotating cameras.
Answer:
DescriptionA storm surge, storm flood, tidal surge or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low pressure weather systems, the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.
