Which quantity best describes this description? justin walks at 3 miles per hour north, and then speeds up to 4 miles per hour.

(this is a question from ipc,)

i just wanted to check with

the answers are:

a. acceleration
b. velocity
c. inertia
d. speed

i went with acceleration, but it could also be velocity, since it's walking in a certain kind of direction.

i wanted to know if anyone else had thoughts, or if i should change my answer to b?

Personally, I agree with your answer, namely that the likely-intended event happening here is one of acceleration. Having said that, I also want to add: it pains me to see this type of wording because, clearly, it is vague and only invites confusion of the type you are talking about.

Good luck!

so easy. just google the electromagnetic waves and it’ll pop up.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
