Answer:
Explanation:
According to ohm's law current flowing in a conductor is directly proportional to the voltage applied across two end of conductor.
i.e. 

where R=resistance


whee L and d are length and Diameter
thus 
where k=constant of Variation
By using the equation speed = distance/time we can solve for distance. The speed is 4 m/s and the time is 12 seconds. We need to rearrange the equation to Speed * Time = distance. 4(12) = 48; 48 = distance. The cliff is 48 meters high.
Answer:

Given:
Object distance (u) = 25.0 cm
Image distance (v) = -50.0 cm
To Find:
Magnification (m)
Explanation:

Substituting values of Image distance(v) & Object distance (u) in the equation:

-(-50) = 50:



Meteor maybe?
I’m pretty sure it’s meteor but if not sorry
