Answer:
Let me look up a couple of things regarding this question.
Explanation:
Then I will get back to you.
Answer:
-------1
Explanation:
beacuse that is what i know
A) use v=u+at for both
First section, v=27, u=0, a=2.4. You should get 11seconds.
Second section, v=0, u=27, a=-1.3. You should get 21seconds.
This means that the total time is 22seconds.
b) You can either use s=ut+0.5at^2 or v^2=u^2+2as. Personally, I would use the second one as you are not relying on your previous answer.
First section, v=27, u=0, a=2.4. You should get 152m.
Second section, v=0, u=27, a=-1.3. You should get 280m.
This makes your overall displacement 432m.

Explanation:
A graduated cylinder measures the volume of a liquid.
A stopwatch measures the amount of time that elapses.
A scale measures the mass of objects.
A thermometer measures the temperature of any object.
Because we are measuring rain, a liquid, we would want to use a tool that would allow us to collect the rain for measuring. Therefore, the tool e would use to measure the amount of rainfall would be A. a graduated cylinder.
