Answer:5seconds

Explanation:

initial velocity(u)=0

Final velocity(v)=49m/s

acceleration(a)=9.8m/s2

Time(t)=?

V=u+axt

49=0+9.8xt

49=9.8t

t=49/9.8

t=5seconds

Which statement BEST describes the condition of steady-state equilibrium? - System slowly adjusts to long-term changes in input
krok68 [10]

Answer:

System inputs and outputs fluctuate around a stable average so the system does not move far from its average condition.

Explanation:

Steady-state equilibrium can also be called dynamic equilibrium. The main difference between the two is the type of system we are considering. When a system is closed, and it attains equilibrium, there is no transfer of energy. In  the case of an open system, even if the system achieves equilibrium there will be some transfer of energy but it will not deviate far from it's equilibrium point, that is, it will be in a steady-state.
