Q2
- A.
  
  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
B. B

Explanation
Resistance should be the same for any of them, so use V=IR to find the resistance for each row, A,C,D all get a resistance of 2.4 ohms. B is different

- C.
  
  C
- D.
  
  D

B. B

Explanation
Largest current will come from wire of lowest resistance, so short length and thick

- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
A. A

Explanation
When rubbed together one object will GAIN electrons (negative) and the other LOSE electrons (positive) opposite charges, and they would attract

Q6
- A.
  
  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
C. C

Explanation
need to increase length AND make it thinner (if make shorter but thinner these have opposite effects as shorter reduces resistance)

Q7
- A.
  
  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
A. A

Explanation
Meter x must be current as in series, Y voltage as around the resistor.
Normally voltages are larger than currents so thats why C is not right (also can use V=IR to check)

  A
- B.
  
  B
- C.
  
  C
- D.
  
  D
Correct Answer
B. B

Explanation
Static needs INSULATORS, glass and plastic are only options (electrostatic = static)
