A large ship is being towed by two tugs. The larger tug exerts a force which is 30 percent greater than the smaller tug, and at an angle of 25 degrees north of west. Which direction must the smaller tug pull to ensure that the ship travels due west

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
