A=2i-3j+7k, b= i+2k, c=j-k find a. b×c

The value of is 0.

Explanation:

The three vectors provided are:

The value to be computed is:

Compute the value of (b × c) as follows:

Now compute the value of as follows:

Thus, the value of is 0.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
