Several employees in a newly formed group must work together to develop a new product. no one in this group has worked with anyone else in this group before and the development of this product has not been attempted previously. according to the media richness model, which of the following communication channels is most appropriate in this situation?

Face to face meetings

Explanation:

In this case the employees are all new to each other, they don't understand each other, they don't know how to relate with each other and have never worked with each other, so for them to be able to function effectively and efficiently they need to organise a face to face meeting where they can get to know each other and share their opinions about the project. According to media rich model face to face meeting/interviews are the best form of communication when uncertainty and equivocality may be involved.

the earthquake in haiti was a magnitude of 7.0 according to the u.s geological survey yet the smaller earthquake in haiti killed more than 200,000 and left more than 1.2 million people homeless. the chile earthquake was a magnitude of 8.8 and 500 times more stronger but chile's earthquake only injured 712 people.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
