Answer:
Resistance is a measure of the opposition to the flow of current in an electrical circuit.
Explanation:
It is symbolized by the Greek letter omega (Ω), resistance is measured in ohms.
If an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm
Answer:
1.6 x 10^-5 T
Explanation:
i = 4 A
r = 0.05 m
The magnetic field due to long wire at a distance r is given by

B = 10^-7 x 2 x 4 / 0.05
B = 1.6 x 10^-5 T
Answer:
research topic and research question (hypothesis)
Explanation:
Answer:
Particles in a water wave exchange kinetic energy for potential energy. When particles in water become part of a wave, they start to move up or down. This means that kinetic energy (energy of movement) has been transferred to them
