Number a is a correct one
<span>I think the average velocity b/w t =a and t= b would be
Avg vel. = change in vel./ change in time</span>
Proxima Centauri is approximately 4x1013 kilometers away from the sun. Which multiplies up to 40,000,000,000,000 km. Hope I helped! Thanks for asking us here at Brainly! Feel free to ask more questions at anytime!
Answer:
This is because, the flywheel has a very large moment of Inertia and hence sudden piston torques have negligible effect on the flywheel, but every piston combined has a significant torque. This smoothens out the vibrations.
Explanation:
Answer:
7.15/2 = 3.575m
1.78cos(45.4) = 1.25m
radius = 3.575 + 1.25 = 4.825 m
mg of seat = 10 x 9.8 = 98 N
98/sin(45.4) = 137.64 N
Horizontal force = 137.64cos(45.4) = 96.64 N
Centripetal force = 96.64 N
96.64/10 = 9.6644 = ca
9.6644 x 4.825 = v^2 = 46.63, sq-root = v = 6.83 m/s
(10 + 28.3) x 9.8 = mg = 375.34 N
375.34/sin(45.4) = 527.14 N
