Ahorse performs 2600 joules of work pulling a wagon for 13 seconds. what is the horse's power? 33800 w 200 w 0.005 w 2600 wa horse performs 2600 joules of work pulling a wagon for 13 seconds. what is the horse's power?

33800 w

200 w

0.005 w

2600 w

200 W

Explanation:

The power is given by the ratio between the amount of work done and the time taken to perform the work:

where in this problem we have

W = 2600 J is the work done

t = 13 s is the time taken to do the work

Substituting the numbers into the equation, we find

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.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
