4. E A charge of−8.3휇C is traveling at a speed of 7.4 × 106 m/s in a region of space where there is amagneticfield. The angle between the velocity of the charge and thefieldis 52°. A force of magnitude5.4 ×10−3N acts on the charge. What is the magnitude of the magneticfield?

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.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
