ASAP: A bird lands on a wire. When the bird comes to rest, the wire experinces tension on the two sides of the bird. The tensions on both sides of the bird are 30.5N oriented at 21.0 above the horizontal. What is the mass of the bird

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
