Answer
Mass m = 78 kg
Vertical height in each stage h = 11 m
(a).
Initial speed u = 0
Final speed v = 1.1 m / s


a = 0.055 m/s²
Work done




(b).Work done

W_b = 78× 9.8× 11

c)
Work done

Where V = final speed
= 0
v = 1.1 m / s
for deceleration a = -0.055 m/s²
now,

W_c = 545.75 × 11

Answer:
the answer is tropical rainfores
Explanation:
Formula depicting relation between total flux and total charge Q is as follows.
(Gauss's Law)
Putting the given values into the above formula as follows.
Q =
= 
= 
= -8.4 nC
Therefore, when the unknown charge is q then,
-14.0 nC + 33.0 nC + q = -8.4 nC
q = -27.4 nC
Thus, we can conclude that charge on the third object is -27.4 nC.
The answer is B, because oxygen and sulfur are in the same group (group 6A)
