A pickup truck has a width of 78.1 in. If it is traveling north at 36 m/s through a magnetic field with vertical component of 41 μT, what magnitude emf is induced between the driver and passenger sides of the truck?

The magnitude of induced emf is 0.115 volts.            

Explanation:

Given that,

Length of the truck, l = 78.1 m

Speed of the truck, v = 36 m/s

The vertical component of magnetic field,

We need to find the magnitude of emf induced between the driver and passenger sides of the truck. It is a case of motional emf. The induced emf is given by :

So, the magnitude of induced emf is 0.115 volts.

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

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.
