Answer:
Fraction of engine is 0.23
Explanation:
Given Data
m=700 kg
v=2.5 m/s
Fraction=?
Solution
Work done against gravity is given as
P=Fv
where F=mg
So
P=mgv
P=(700kg)×(9.8m/
)×(2.5m/s)
P=17.15 kW
To find Fraction

AC or DC
someone use active current or Direct current
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
