is so confusing like I’m just trying to pass. I’m stuck on my physics class in the momentum and conservation of momentum tutorials and mastery tests on edmentum.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.

Which of the following list the divisions of the geologic time scale in order from longest to shortest

Which type of reaction is shown in this energy diagram ?
