The famous motorbike artist evel knievel enjoys jumping. he departs from an inclined plane witha velocity of 100 km/h and no rotation. he wants to try a summersault while he is airborne within 2 s. based on the conservation of angular momentum, he will start to rotate if his wheels' rotation is slowed down. his wheels are hollow cylinders with a radius of 0.4 m and a mass of 10 kg. the inertia of the bike and him is 200 kgm2. calculate, how much the wheels' rotation has to be modified in order to make a full rotation of the bike during 2 s. let's assume the angular velocity can be changed within 0.1 s which angular acceleration does that correspond to?

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

show the wavelengths of a wave. show the crests of a wave.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
