Use the following photoelectric graph to answer the question: Photo electric Effect for a Photomis sive Metal NA Kinetic Energy (en) Frequency (E14 Hz) If the incoming photon had a frequency of 2.0 E14 Hz, would you have a photo-electron ejected? (5 points)​

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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.
