Velocidad angular = (angulo total) / (tiempo total)

Velocidad angular = (1080 grados) / (20 segundos)

Velocidad angular = (1080/20) g/s

Velocidad angular = 54 g/s

Pero 180 grados = π radianes

V.A. = (54 g/s) x (π rad / 180 g)

V.A. = (54π gr-rad / 180 seg-gr)

V.A. = 0.3π rad/seg

V.A. = aproximadamente 0.942 rad/seg

A scientist wants to measure the relationship between humidity in the

ICE Princess25 [194]

Answer:

Explanation:

The most suitable testable question. in this case, would be that 'are there more home runs during the more humid months of the summer?'

Since the aim of the investigation is to find the relationship between humidity and the number of home runs, measuring the number of home runs during the more humid months in the summer and comparing the data to the number of home runs during the less humid months in the same summer would provide the answer.

Only option D raises a valid question that is relevant to the aim of the investigation.
