A projectile is launched from point A with an initial speed v0 = 100 ft /sec. Determine the minimum value of the launch angle for which the projectile will land at point B.

Ithink the answer would be a

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 !

How are period and frequency related to each other? dperiod is the reciprocal of frequency.
