Answer:α = 1.00 rad/s², τ = 90.0 N•m, KEr = 1.12 kJ
Explanation:
m = 795/9.81 = 81.0 kg
ω₁ = 47.79 rev/min(2π rad/rev) / (60 s/min) = 5.00 rad/s
α = (ω₁ - ω₀)/τ = (5.00 - 0.00)/5.00 = 1.00 rad/s²
I = ½mR² = ½(81.0)(1.49²) = 90.0 kg•m²
τ = Iα = 90.0(1.00) = 90.0 N•m
KEr = ½Iω² = ½(90.0)5.00² = 1,124.477 ≈ 1.12 kJ
Natural was thought to be straight up or straight down and violent was thought to be the result of a push or pull
Answer:
Combine to form heavier elements
Explanation:
as opposed to fission which splits heavier atoms into lighter elements.
Pretty sure it's C - The Earth is rotating from East to West. It's the only answer that really makes sense.
D. Equilibrium
Heat always diffuses from areas with lots of heat to lower heat, meaning once they are equal they will stay the same.
