6 physics questions, help please

Question

1. Does the charge that flows into the capacitor during the charging go all the way through the capacitor and back to the battery, or does it get stored somewhere in the capacitor?

a. It goes all the way through the capacitor and back to the battery.

b. It gets stored somewhere in the capacitor.

2. The direction of an electric field is defined as the direction of the force on a

a. negative test charge.

b. positive test charge.

c. either a positive test charge or a negative test charge.

3. Bulbs convert moving charge to light and heat.

a. True

b. False

4. If the cross-sectional area of a fixed length of wire were decreased, the resistance of the wire would

a. decrease.

b. increase.

c. remain the same.

5. How does increasing the number of resistors in a parallel branch change the total resistance of the system?

a. Decreases the total resistance of the circuit

b. Increases the total resistance of the circuit

c. Increases the total resistance of the circuit if the resistance of the added resistor is larger than the resistors already in the branch

d. Decreases the total resistance of the circuit if the resistance of the added resistor is smaller than the resistors already in the branch

6. What is the intensity of an electric field at a point where a 0.50 C charge experiences a force of 20. N?

Answer 1

1.b

2.b

3.b

4.b

5.a

6.according to the equation F=qE

then E=F/q==40 Newton/meter
