Horizontal electric power lines supported by vertical poles can carry large currents. assume that earth’s magnetic field runs parallel to the surface of the ground from south to north with a magnitude of 0.50×10−4 t and that the supporting poles are 38 m apart. 1) find the magnitude of the force that earth’s magnetic field exerts on a 38-m segment of wire carrying 95 a if the current runs from north to south. (express your answer to two significant figures.)

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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

i believe the answer is a hope it and is correct
