a)Gamma
Explanation:
Gamma rays are chargeless. So they cannot be deflected by electric or magnetic fields
Answer:
3.6 Ω
Explanation:
Resistance: This is defined as the opposition to the flow of current in an electric circuit. The S.I unit of Resistance is Ohm's (Ω).
From the question above,
Applying Ohm's law
V = IR...................... Equation 1
Where V = Voltage, I = current registered by the ammeter, R = Resistance.
make R the subject of the equation
R = V/I............... Equation 2
Given: V = 9 V, I = 2.5 A
Substitute into equation 2
R = 9/2.5
R = 3.6 Ω
Hence the resistance of the wire = 3.6 Ω
