Answer:
Answer for the question is given in the attachment.
Explanation:
Use ideal gas equation, with T constant.
pV =nRT => pV / n = RT = constant
n = K* [units of particles]
pV / [units of particles] = constant
13 psi * 160 mL / 15 units = p * 150 mL / 10 units =>
=> p = [13psi*160mL/15units]*[10units/150mL] = 9.2 psi
The answer is b) force exponerse by charge in electric field
Answer:
By induction method
Explanation:
Induction method involves charging an electrically neutral body by bringing it in contact with an electrically charged body.
For the electrophus, a charge opposite that on the slab is induced on the side in contact with the slab; driving the opposite charge (this will be the same as that on the slab) to the other end of the elctrophus. Touching the electrophus removes the charge opposite the charge induced on the electrophus by the charged slab either by drawing up charge from the earth or taking the charge to earth (depends on the charge. A negative charge is drawn to earth while a positive charge draws up electrons from the earth)
