Two current-carrying wires are perpendicular to each other. The current in one wire flows vertically upwardand the current in the other wire flows horizontally toward the east. The horizontal wire is 1 m south of the vertical wire. What is the direction of the net magnetic force on the horizontal wire? Explain.

There is no net magnetic force on the horizontal wire.

Explanation:

The magnetic field due to vertical wire is in same plane in which the horizontal wire is present.

Magnetic force on the wire is given by the formula:

F = I L B sin θ  

Where, I is the current through the wire, L is the length, B is the magnetic field strength and θ is the angle between the direction of current and magnetic field.

As θ = 0, therefore F =0

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
