15) Light with λ = 420 nm in incident normally onto the flat side of a plano-convex lens which is resting on a glass plate parallel to the flat side of the lens and forms a pattern of concentric luminous and dark rings (Newton's rings). The radius of the second dark ring is 2.0 mm. What is the radius of curvature of the curved side of the lens?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

false

hope this : d
