Answer:
The answer is below
Explanation:
The initial velocity = u = 82.5 km/h = 22.92 m/s, the final velocity = 32.5 km/h = 9.03 m/s, diameter = 91.55 cm = 0.9144 cm
radius (r) = diameter / 2 = 0.9144 / 2= 0.4572 m
a) Initial angular velocity (
) = u /r = 22.92 / 0.4572 = 50.13 rad/s, final velocity (ω) = v / r = 9.03 / 0.4592 = 19.67 rad / s
θ = 95 rev * 2πr = 95 * 2π * 0.4572= 272.9 rad
angular acceleration (α) is:
b)
c) θ = 95 rev * 2πr = 95 * 2π * 0.4572= 272.9 rad
a) When it stops, the final angular velocity is 0. Hence:
θ = 323 rad
C is the right image for that biological process.
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.
Answer:The anwser is B i Promise ok
Explanation:
High amplitude sound would be music, radio, or earthquakes.
Low amplitude sound would be a breeze or wind.
