How much power is used if a force of 35 newtons is used to push a box a distance of 20 meters in 5 seconds

140 W

Step-by-step explanation:

Power is measured in joules per second, or watts. A joule is a measure of energy equal to 1 newton-meter. These unit relationships tell you how to combine the numbers:

power = (35 N)(20 m)/(5 s) = (35·20/5) N·m/s = 140 J/s = 140 W

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
