The dog walked 5 meters backwards in the first 10 seconds, then 5 meters forward from 10-20 seconds. After 20 sec he was back where he started. Displacement (20sec) = zero.
Lol i think i had the same worksheet!! lol anyway look up newtons first law and it will be pretty self explanatory from there
Answer:

Explanation:
From the question we are told that
The hydraulic conductivity is 
The effective matrix potential 
The intensity of rainfall is 
The runoff rate 
Generally the run off rate is mathematically represented as

Here t is the amount of runoff generated
=> 
=> 
converting to minutes

The equation formula:
P V = n R T
1,245 * 2 l = n R * 300 K
n R = 1,245 * 2 : 300 = 8.3
P * 2.5 l = n R * 400 K
P * 2.5 = 8.3 * 400
P = 3,320 : 2.5 = 1328 J
Answer: A ) 1,328 joules.
The least amount of inertia would be the one with least mass.
Of all the options, the smallest mass is likely the insect the cricket.
