A.rock breaking and D movement below ground
Answer:
1.53 g
Explanation:
Given,
Initial speed = 30 m/s
Final speed = 0 m/s
Period of stretch, t = 2 s
average deceleration = ?
we know


a = -15 m/s²
Deceleration of the jumper = 15 m/s²
Deceleration in terms of g


Hence, the deceleration of the jumper is equal to 1.53 g
Your answer should be A, because every reaction has an equal opposite reaction
Explanation:
Drinking water requirement in town 2.0 m^3/s of water per second
nitrate in local well nitrate per 15
of water
nitrate in distant reservoir 
Let the flow rate of well
flow rate of reservoir 
Drinking water requirement is
or 
therefore, the total flow of drinking water
