The horizontal component of the motion is irrelevant.
The ball starts with a vertical velocity of 0 metres per second and has an acceleration of 9.8 metres per second squared.
It travels 50 metres so s = 1/2*g*t^2
that is, 50 = 1/2*g*t^2
therefore t^2 = 10.2
and so t = 3.19 seconds.
Answer: 44 meters
Assuming you throw the rock horizontally off the cliff it drops down at the acceletrtion of gravity. height= 1/2 gt^2 With g = 9.8 m/sec and t = 5 seconds we have height = (1/2) (9.8)(5)(5) = 122.5 meters notice it has nothing todo with the 50 meter distance, which depends on the horizontal velocity.
the meter socket should be 1.8m from finished ground
We have no idea how big the rock is, and no way to figure it out. But we can calculate that it reaches 11.48 meters above the ground before it starts falling.

Answer: 44 meters
The impact velocity of a rock thrown horizontally from a cliff will depend on the height of the cliff and the initial velocity at which it was thrown. If air resistance is neglected, the velocity of impact will be equal to the horizontal component of the initial velocity.
Assuming you throw the rock horizontally off the cliff it drops down at the acceletrtion of gravity. height= 1/2 gt^2 With g = 9.8 m/sec and t = 5 seconds we have height = (1/2) (9.8)(5)(5) = 122.5 meters notice it has nothing todo with the 50 meter distance, which depends on the horizontal velocity.
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!

A meter stick is a stick that, when rolled along the ground, click's every meter

If the meter is sensitive enough and there is a resistance between the neutral and ground then the meter should be able to detect it.
To ground a meter box, usually a grounding electrode conductor is connected to a grounding electrode, such as a ground rod, buried in the earth near the meter box. This provides a path for excess electrical current to safely dissipate into the ground, preventing potential hazards. It is important to follow local electrical codes and regulations when grounding a meter box.
To ground a home gas meter, you need to follow your local building codes and regulations. Typically, this involves connecting a copper wire from the gas meter to a grounding rod installed in the ground near the meter. It is important to hire a qualified electrician to ensure the grounding is done correctly and safely.
