Un puente(construido de acero) que conduce hacia una bahía mide 1.30X10-3m entre sus torres de apoyo. ¿Cuánto se dilata el puente durante un día en el que la temperatura alcanza una diferencia de 30°C?

Where are the options ?

If its history of, then b) because a) implies only present day (now)

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 !

The object needs to be bigger than you, or (most people would say) you’d be attracting it. no matter how small an object is, if it has mass, it has gravity.
