You're the operator of a 15,000 v rms, 60 hz electrical substation. when you get to work one day, you see that the station is delivering 6.10 mw of power with a power factor of 0.940.

what is the rms current leaving the station?

how much series capacitance should you add to bring the power factor up to 1.0?

how much power will the station then be delivering?

Astudent pushes on a 20.0 kg box with a force of 50 n at an angle of 30° below the horizontal. the box accelerates at a rate of 0.5 m/s2 across a horizontal floor. what is the value of the normal force on the box? 200 n 243 n 156 n 225 n

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.
