Answer:
A. 112 J
Explanation:
KE = ½mv² = ½(0.14)40² = 112 J
Answer:
ok so
Explanation:
Im not sure rn but ill get back to you.
Answer:
Speed; v = 17 m/s
Explanation:
We are given;
Radius; r = 110m
Angle; θ = 15°
Now, we know that in circular motion,
v² = rg•tanθ
Thus,
v = √(rg•tanθ)
Where,
v is velocity
r is radius
g is acceleration due to gravity
θ is the angle
Thus,
v = √(rg•tanθ) = √(110 x 9.8•tan15)
v = √(288.85)
v = 17 m/s
Ok, condensation is part of the water cycle. Acid rain comes from acidic air pollution. Burning fossil fuels is a green house gas that contributes global warming. I'd have to go with B.
