5m
Explanation:
Given parameters:
Weight of object = 50N
Work done in lifting object = 250J
Unknown:
Vertical height = ?
Solution:
The work done on an object is the force applied to lift a body in a specific direction.
Work done = force x distance
Weight is a force in the presence of gravity;
Work done = weight x height of lifting
Height of lifting = 
Height of lifting =
= 5m
The vertical height through which the object was lifted is 5m

Actually the third one is introns, trust me I did the test
Answer: Nucleosynthesis
Reason: the definition for this is “the is the process that creates new atomic nuclei from pre- existing nucleons”
Hope this helps
