Understanding Acceleration: Remember, acceleration is speeding up, slowing down, or changing direction. Derections for the following statements. If a statement describes acceleration, say on Yes. If the statement does not describe acceleration, say on No.

1. Your pet dog runs around in circles, chasing his tail. *
Yes
or
No
2. A car slows down as it comes to a red light. *
Yes
or
No
3. You pedal your bicycle at a speed of 5km/hr. *
Yes
or
No
4. As you see your friend approaching, you jump up from your chair and run over to greet her. *
Yes
or
No
5. Your brother walks across the room to open the window. *
Yes
or
No
6. You begin to walk faster when you sense that someone is following you. *
Yes
or
No

Your answer should be:

1. No

2. Yes

3. No

4. Yes

5. No

Have a wonderful day!

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
