PHYS 165 FINAL EXAM
Which declaration pleasant describes the medical method?
A systematic technique used to find a method to a problem
__________ can be concept of collectively as objects in nature
count number
an amazing hypotheses is one that is both _________ and ________
manageable and testable
while an boom inside the independent variable reasons the depended variable to increase that
is called an
direct share
which of the subsequent high-quality describes a principle
an cause of patterns in nature this is supported by using scientific proof and verified a couple of
instances via numerous agencies of researchers; this is a broader clarification of large portions
of nature
which of the subsequent is a size of time?
The second one
which of the subsequent is a measurement of electric cutting-edge?
The ampere
which refers to the settlement of several measurements among eachother?
Precise
how many sig figs are in 5,302,000?
4
,what number of sig figs are in 0.05021 kg?
Four
how many sig figs are in 5.20x10^6 m?
3
classical physics is an exquisite approximation as long as three matters are true. Which of the
subsequent statements is such a three things?
Remember must be transferring at speeds much less than about 1% of the velocity of light
except factors which are specific to the state of affairs, the factors contributing to uncertainty in a
size include:
barriers of the measuring tool, the skill of the character making the size.
The mass of a block of wooden is suggested as 548 +/- 21g. What is the percent uncertainty?
21g/548g x one hundred%=3.8321 ---> three.8%
the time for a drag race is 17.5 s +/- 8.1%. What's the absolute uncertainty?
17.5s x 8.1% = 1.4175 ---> 1.4s
convert zero.7km to meters
0.7km x 1000m/1km = 700m
convert 7200 mg to grams
7200mg x 1/1000mg = 7.2g
someone runs a race in 12,710s. What number of minutes is this time?
12,710s x 1min/60s= 211.8min
what do you get when you divide forty two.0m through 15.0s?
, Forty two.0m / 15.0s= 2.80m/s
in an test, the factors that affect the time it takes a ball to fall are being examined. During one
set of trials, the height from which the ball is dropped is systematically improved, and the
resulting time it takes the ball to fall is measured. The whole time the same ball is used. Identify
the impartial, structured, and controlled variable.
Impartial: top of the drop
dependent: time it takes to fall
managed: which ball is used
describe the position of experimentation in technology
experimental records can result in laws and theories, it is able to also refute presently standard
laws and theories. Statistics that has experimental information supporting argument is more
reliable than records that does not have helping experimental facts
you stroll into your bed room and discover your preferred machine damaged into portions in the
floor. Use the 6 steps of the clinical method to discover what occurred to the gadget
1. Discover the trouble- how did my smartphone get damaged?
2.Gather facts- my mom, father, and little brother could have been in my room today.
Three.Create a hypotheses- my brother knocked my cellphone off the table and broke it.
Four.Increase the speculation- my brother additionally broke my IPAD the day prior to this
five.Test the hypotheses- ask my brother if he broke those items
6. Evaluation of the hypotheses- he said no and I believe him so I have to move lower back to
the beginning of the list and try once more.
What is the first-rate definition of a reference body?
A set of objects which can be taken into consideration to be stationary this is used to describe
the motion of objects
a bodily amount that simplest has significance is called a
vector
classify distance as a vector amount or a scalar amount
scalar
