Answer- I would think low
Answer:
- Wind resistance made decrease in speed
-Gravity/Mass made decrease in velocity
Explanation:
Answer:
14.2 m/s
Explanation:
Given data:
Speed of the stream, v₁ = 7.1 m/s
let the cross section area at initial point be A₁
now area at the second point, A₂ = (1/2)A₁ = 0.5A₁
now, from the continuity equation, we have
A₁v₁ = A₂v₂
where, v₂ is the velocity at the narrowed portion
thus, on substituting the values, we get
A₁ × 7.1 = 0.5A₁ × v₂
or
v₂ = 14.2 m/s
Solar energy - A
nuclear energy - B
fossil fuel energy - C
wind energy - D
geothermal energy - E
It protects us from the magnetic/electrical radiation that comes from the sun. High radiation periods coincide with solar storms.
