Answer: (1, 30), (2,10), (3,40), (4,20)
Explanation:
Answer: The magnetic field is 4×10^-4T
Explanation:
Using the magnetic field equation
B=μI/2πr
B= magnetic field =?
l= current in the wire=2.0A
r= distance from the axis of wire=1.0mm= 0.001m
μ=magnetic permeability =4π×10^-7N/m
B= (4π×10^-7 × 2.0)/(2π × 0.001)
B= 4×10^-4T
Therefore the magnetic field is 4×10^-4T
There must be a equal opposite reaction.
E=mv2
Answer:
150 g= 0.15 kg
Momentum = mass * velocity
= 0.15 * 3
= 0.45 kg m/s
