Answer:
Velocity = 94.85m/s
Explanation:
<u>Given the following data ;</u>
Height = 1200m
Vertical distance = 1050m
To find the time, we would use the second equation of motion;
Substituting into the equation, we have;
t = 11.07 secs
To find the velocity;
Mathematically, velocity is given by the equation;
Substituting into the above equation;
Velocity = 94.85m/s
Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.

Answer:
Eddy currents
Explanation:
When a magnetic flux linked across the coil changes, an induced emf is developed in the coil and hence the induced current is also developed in the coil.
If the induced current in the large conductor, the current is called eddy current. It produces the heating effect.
There are several applications of the eddy current.
(1) Electromagnetic brakes
(2) Induction furnace, etc.
To minimize the effect of eddy current we use choke coils, in which the core is made of laminated thin sheets.
Answer:
Nicolaus Copernicus
Explanation:
With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it.
Answer:
2276.1 N
Explanation:
We are given that
Mass of person,m=62.3 kg
Initial velocity,u=0
Final velocity,v=0
Initial kinetic energy=Final kinetic energy=0
y=3.11 m
d=1.14 m
h=3.11+1.14=4.25 m
Final height, h'=0
Work done=Change in P.E energy
