Answer: 12,600,000Cm
Explanation:
From the data's;
Charges(q) = 1.8 PC equal to 1.8 x 10^¹²C
Distance = 7 micrometer, is equal to 0.0000070m
From the equation of electric dipole moment, p= q x d, where q= charge, d=distance and p is the dipole moment.
Then we have 1.8x10^¹² x 0.0000070= 12,600,000Cm
NB: The charges are identical.
Advantages of copper cables are that copper is an extremely powerful conductor of electricity and much more stable over time. It can withstand higher temperatures than aluminum and is more resistant to damage.
Disadvantages: Copper is more expensive and heavier and thus requires structural support.
Advantages of aluminum cables are that it is less expensive, easier to work with and light weight and so does not need structural support when strung over long distance.
Disadvantages: Aluminum is more susceptible to corrosion and requires periodic replacement. It needs much greater maintenance.
Advantages of steel cables are that steel does not rust, is fairly cheap and readily available. It has a higher tensile strength too.
Disadvantages: Steel cables are less ductile and are therefore more susceptible to fatigue.
Answer: It would be 125 J
Answer:
180^2 + 390^2 = force ^2 (Pythagoras) root of force^2 = 429.5N approx resultant force Acceleration = Force/Mass 429.5/270 = 1.5907 ms^-2 in a Southwesterly direction.
