Aparticle moves in a plane elliptical orbit described by the position vectort- 2b sin(ot)1+ b cos(ot)0. (a) find the velocity, the acceleration, and the speed of the particle. (b) determine expressions for the velocity and the acceleration and find the angle between them at the time t-t/2o

Look it up you feel me

Ireally don’t know

Because they're in different places for this the temperature varies.

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 !
