newtons laws
F=MA
speed=
Distance/Time
homozygous
AA or aa
if wanting to test the relationship between screen time and sleep quality, what type of graph would be made from the experiment
line/scatter
force on car stopping the cars inertia
brakes
the reason why you move forward when someone slams on the brakes
1st law- inertia
acceleration=
(final speed-initial)/time
co-dominance
both traits are shown in the offspring
see graph- identify the trend
as people have more social media friends the more faces are perceived.
object stopping your inertia in a front on collision
seatbelt
3rd law
equal and opposite reaction
newtons for 100 kg motorbike to accelerate at 10 m/s/s
1,000
f=ma
genotype for II-3
Aa
see graph- draw a conclusion about the effect of sleep on the amount of correct answers
with more sleep, the number of correct answers increased
this is manipulated by crumple zones
2nd law- (de)acceleration takes longer meaning less force
using any of newtons laws- why A380 planes have 4 engines compared to smaller planes with only 2
2nd- more force needed because more mass for same acceleration
or
3rd-more speed for more air particles pushed down, pushing plane up
usain bolt weighs 94 kgs. his world record run was done in 9.58 seconds. his final speed was 12 m/s. calculate his acceleration
1.25 m/s/s
result for an x-linked trait cross between a heterozygous mother and recessive trait father
XAXa + XaY -->
1 XAXa : 1 XaXa : 1 XAY : 1 XaY
see graph- like the rat man experiment, where people were shown images that can be percieved differently. which condition has more precise data
outdoors
stops whiplash as a result of 1st law
head rest
almost zero rocket fuel makes it into space after a launch. why referencing all 3 laws
3rd: rocket exhuast pushes down pushing rocket up
2nd law- force needed to overcome earths gravity requires acceleration
1st law- no force stopping inertia in once space
rocket accelerates 9 m/s/s in 7 seconds from rest.
calculate the final velocity
* acceleration= (final- intial)/time
63 m/s
blood types with A and B being codominant, while o is reccessive to both. result of blood types from parents being heterozygous type A and heterozygous type B
Ao X Bo -->
1 AB : 1 Ao : 1 Bo : 1 oo
p value- is done to determine if there is a significant difference between 2 groups. what is the number that indicates if a difference is significant
p= <0.05
the amount of damage a tissue box in the backseat window cause in a car crash.
nothing- myth busters tested this. tissue box does not have enough mass to make any significant damage.
