I need help with this asap You went to coconino national forest at flagstaff for a five day/s camping trip. you started from base camp. the first day, you hiked 25 km in a direction 60 degrees north of east; second day hiked 31 km 39 degrees north of west; third day, hiked 29 km 21 degrees south of east; fourth day, hiked 18 km 45 degrees south of west; and on the fifth day, you hiked 48 degrees north of west. what is the resultant displacement from the base camp?
(use component's method. figure out the direction and magnitude of the resultant displacement vector)

Um vetor representa um deslocamento cujo módulo é 20 m. se v faz um ângulo de 60 graus com a horizontal, qual é o valor das componentes horizontal e vertical deste vetor?

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.

Iwill give brainliest if you answer right : )
