Make a puzzle and each puzzle piece represent a state
B. Universal Gravitational Law
Answer:

Given:
Initial velocity (u) = 0 m/s
Final velocity (v) = 44 m/s
Acceleration (a) = 5 m/s²
To Find:
Time taken (t)
Explanation:
From equation of motion we have:

By substituting value of u, v & a in the equation we get:

Answer:
Electric field, 
Explanation:
Given that,
Charge, 
We need to find the magnitude of electric field 17.1 cm (0.171 m) above an isolated charge. Electric field at a point is given by :



So, the electric field is
. Hence, this is the required solution.
