All the members of a construction crew work at the same pace. six of them working together are able to pour foundation in 22 hours.

how many hours will this job take if the number of workers increased by a factor of 4?

It will take additional 4 workers to complete the work in 13.2 hours

Step-by-step explanation:

Given:

6 men complete the work in 22 hours

we need to find number of hours to complete the work when workers are increase by 4 i.e with 10 workers

Solution:

6 men complete the work in 22 hours

hours taken for 1 men to complete the work =

∴ hours taken by 10 men to complete the work =

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
