En un depósito de gran capacidad, lleno de
agua, se tiene un orificio situado a 8 m por
debajo de la superficie libre del líquido.
Sabiendo que en dicha superficie se ejerce
una presión de 208 kPa, determinar la
velocidad, en m/s, del chorro de agua que
sale por el orificio. (2g m s = 10 /).
a) 8
b) 12
c) 16
d) 24
e) 20

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
