A Styrofoam ball with a charge of -1.00 x 10-6 C experiences an upward force of 0.0200 N in an electric field. What is that electric field

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

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 is not a transverse wave? a) soundb) lightc) radiod) all of thesee) none of these
