Homework Statement What would be the effect of calculated value if: a. Jockey weight is in error by 1 g? b. Distance from vane center to pivot point is in error by 1 mm? c. diameter of nozzle 0.1mm different from actual nozzle diameter. Homework EquationsThe Attempt at a Solution as the error...

E.P.E =qV

V = kq/r ?

kq^2/r2 represent the electrostatic force between the two charges

so instead of kq^2/r^2 = kq^2/d^2 + 1/2m1*V^2 + 1/2m2*V^2. it should be kq^2/r^2 = kq^2/d^2 + 1/2m1*(V1)^2 + 1/2m2*(V2)^2 as the velocity is different. right?

i saw the r and d is highlighted from my computer screen so i thought you asked about it. lol my bad sorry

as i stated r = initial distance and d= final distance.

(3.00 10-3 )x 0 + (6.00 10-3 ) x 0 = (3.00 10-3) x 120 - (6.00 10-3 ) x V i this correct?

(3.00 10-3 )x 0 + (6.00 10-3 ) x 0 = (3.00 10-3) x 120 - (6.00 10-3 ) x V i this correct?

momentum?

Nope.

Homework Statement One particle has a mass of 3.00 10-3 kg and a charge of +8.00 µC. A second particle has a mass of 6.00 10-3 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.100 m...

For the internal energy. I should apply cp or cv? The pressure is constant

Homework Statement a mass of 15kg of air in piston-cylinder assembly is heated from 25°C to 77°C by passing current through a resistance heater inside the cylinder. the pressure inside the cylinder held constant at 300kPa during the process and heat loss of 60kJ occurs. (Cv= 0.718 kJ/kgK)...
