Thanks so much!
If anybody is still looking for the answers to this quiz, I got a 100 with these answers:
1. False
2. C
3. D
4. B
5. D
6. A
7. B
8. A
On number 9, give an example in change of velocity. The change of velocity is known as acceleration, and it is the rate at which velocity changes. The change can be speed, direction, or both. So if you were driving at 50 mph and sped up to 55, you would be accelerating 5 miles per hour. Get it?
If you go to Connexus for the writeing question that Anon answered change stuff around and use different words because now they are finding out if your cheating and I got caught once and I got in trouble so switch words around and use different words, so you don't get caught I'm helping you out
I'm sorry about her, she can be a silly old cow sometimes. But don't cheat in science or math. You CAN cheat in Language arts and social studies, but for some reason this dam site has no social studies pages.
1. False
2. C
3. D
That is all I know! sorry! hope these are useful!
1: false
2: C
3: D
4: B
5: D
6: A
7: B
8: A
9: in system international (SI) or metric units motion involves the unit meters and seconds. The consistency of the units makes it easier for someone from a different country to understand even if they do not speak the same language
the 2021 answers :)
Anon is 100% correct
THANK YOU SO MUCH ANON
You guys are so kewl. Y'all are my fam, fam
1. Nope. If the net forces are zero, it means that the object is at an equilibrium state (may be static of dynamic), and thus implies the forces cancel or balance each other out.
2. It's actually air resistance. I suggest you read about Aristotle's and Galileo's experiment about the topic (gravity).
3. Ain't sure with this one. ^^;
4. Recall that gravitational force can be measure using the formula:
F = G*m1*m2 / r^2
where m1 and m2 are the masses of the objects, and r is the distance between them.
Thus, F is largest when the objects are very massive, and they are close with each other. And therefore, it's "two stars very close to each other".
5. I think it's the rolling friction, because there would be less contact between the tracks and the wheels of the train.
6. It's "a cruise ship travels west at a constant speed". Note in order to have a constant velocity, you must have both magnitude and direction as constant.
7. It's the size of the object. Note that distance, velocity and acceleration are the essential concepts of kinematics.
Hope this helps~ :3
Anon is 100% right!
I got 100% but I only used this site for clarification Haha
Do these answers actually still work?
yes!!1
Anon is right
anon is 100% correct
anon is right
Yay Thanks! 100%
THANKS YALL OML
people have been on here today, that's amazing
meeeee. Georgia studies is hard.😿
but at lets I got a 100 in science.
thanks guys for the thank yous I will help you guys aging some day
Thank you Anon
SYSTEM INTERNATIONAL
LMFAOAOA
Moth thank you so much for the 2021 answers much love !!!!!!!!!
that makes no sense... (@Saredenis)
YEEYEE
OH WAIT IT IS SYSTEM INTERNATIONAL
NVM
