Answer:
0.284 A
Explanation:
We are given that
Mass,m=0.246 kg
Potential difference,V=1.50 V
Efficiency=30.6%
Time,t=7.88 s
Initial speed=0
Speed,v=2.89 m/s
Kinetic energy=
Using the formula
30.6% of Electric energy=K.E
Using the free fall formula for height:
H = 1/2 gt^2 ( height = 1/2 x gravity x time^2)
H = 1/2 x 9.8 x 0.6^2
H = 1.764 meters
I say 1 it seems the most accurate
The biosphere doesn't have clear boundaries because life always comes to a end. The biosphere is the global sum of all ecosystems. The two joined words are "bio" and "sphere". It can also be termed as the zone of life on Earth, a closed system, and largely self-regulating.<span> </span>
