A moving particle encounters an external electric field that decreases its kinetic energy from 8830 eV to 7750 eV as the particle moves from position A to position B. The electric potential at A is -60.5 V, and the electric potential at B is +25.1 V. Determine the charge of the particle. Include the algebraic sign (+ or ?) with your answer.

What is the composition of the last solid remaining prior to complete melting?
water is pump from a lake to a storage tank at 18m above at a rate of 70 ls while consuming 20.4 kw of electric power.
Determine the resulting stress equations for σx, σy and τxy given the Airy's stress function ? = a1x^4 + a2(x^3)y + a3(x^2)(y^2) + a4x(y^3) + a5(y^4), where ai are constants. Also determine, if any, the restrictions between constants.
A 40 mm diameter hole is drilled 3 m deep into the steel shaft. When the two torque are applied, determine (a) the maximum shear stress in the shaft: and (b) the angle of rotation of the free end of the shaft. Use G= 83GPa for steel.
The magnetic flux that passes through one turn of a 12-turn coil of wire changes to 4.0 from 9.0 Wb in a time of 0.050 s. The average induced current in the coil is 230 A. What is the resistance of the wire?
