Un bat golpea una pelota de 400g que se movia horizontalmente hacia la izquierda a 20m/s. La pelota sale despedida por el bat con una velocidad de 60m/s, a un angulo de 30° con respecto a la horizontal. ¿Cuales son las componentes horizontal y vertical del impulso impartido a la pelota?

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:

where are the vectors ?

i think it would be 5
