Jason applies a force of 4.00 newtons to a sled at an angle 62.0 degrees from the ground. what is the component of force effective in pulling the sled horizontally along the ground?

In science and physics what is the standard unit of measure for speed?

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.

The mantle is made up of which structural zones?
