A barrel (mass mLoad) is attached to a massless rope, which is attached to a hook (mass mHook), which is attached to the massless cable of a crane. The cable is accelerating up with an acceleration a. What is the tension of the rope?
1. (mHook+mLoad)·(g-a)
2. mHook·g+mLoad·a
3. mLoad·g+mLoad·a
4. mHook·(g-a)
5. mLoad·a
6. (mHook+mLoad)·(g+a)
7. mLoad·g
8. mLoad·g+mHook·a

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.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
