It’s c
Because velocity; just like speed will be distance over time
However on this case it’s displacement over time
Anyway in case ur wondering ,
the only difference between distance and displacement is that displacement requires a direction
so
100m/4s
=25 m/s to the east since the direction is already mentioned in question
u know u can always look it up
but u can also lok up malkovich earth cycle :)
That rlly long I don’t think a lot of people have courage to do that
If you use chemicals to kill insects, you could risk getting the chemicals in unwanted areas. This could kill plants, animals, and other living things. You could also contaminate water if the chemicals get rinsed/drained into a water source.
