An object experiences no acceleration. Which of the following cannot be true for the object? (a) A single force acts on the object. (b) No forces act on the object. (c) Forces act on the object, but the forces cancel.
1. An object experiences no acceleration. Which of the following cannot be true for the object? (a) A single force acts on the object. (b) No forces act on the object. (c) Forces act on the object, but the forces cancel.
Maaf, jawabannya adalah <C >, karena pernyataan B sangat tepat, sementara untuk opsi A, memang ada sebuah gaya yang bekerja pada benda yaitu gaya berat.
SEMOGA MEMBANTUAn object experiences no acceleration.
Which of the following CANNOT BE TRUE for the object?
(a) A single force acts on the object.
F = m a
F ≠ 0 → a ≠ 0
2. two forces of magnitude 3N and 7N respectively act on body. What are the maximum and minimum resultant forces that act on the body?
Jawaban:
Max = 10 N
Min = 4 N
Penjelasan:
If there are two force act on the same body, the value will be maximum if both of them in same direction so we can add to calculate. Otherwise if one another isn't in same direction, it will be minimum (because we can subtract the big one with the little one)
3. When both forces on an object are the same size, the forces are balanced. True or False?
Jawaban:
true
Penjelasan:
Ketika gaya individu yang diterapkan pada suatu benda memiliki besaran yang sama dan arah yang berlawanan, maka gaya tersebut dikenal sebagai gaya seimbang
4. Find the total work done by forces A and B if the object undergoes the displacement C. Hint : can you add the two forces first? Ini peljrn vektor
work = sigma forces x displacement. Try to find sigma symbol, I cant make is here with my cell phone.
Sigma means kumpulan, kalo bhs indonesia resultan gaya, atau jumlah gaya. Jadi gayanya dijumlahkan dulu terus dikali perpindahan.
5. Which of the following is true ofan object whenever work is doneon the object? *a. The object moves.b. The object accelerates.c. The forces acting upon the object are balanced.d. The forces acting upon the object are unbalanced
The true statement whenever work is done on the object is A,B,and Distruestatement.
PreliminaryHi dude ! Now we will learn about "work (physics)". In the physics, we said work if any force that make anything move (including us) from a place to another place. From the meaning of work, we know that work are depend on two factor. There are :
Force. When you increase the force to move, the number of work is increase too. But, when you decrease the force, the number of work is decrease too.Shifting. When the distance of shifting increase, the number of work is increase too.Problem SolvingLet's go we check again by the option :
(A) : The object movesYes, we know that when the distance of moving is increase, the number of work is increase too. So, even the object starting move, its mean that we have do the work to the object.
(B) : The object acceleratesYes, its a true statement too. We know that we need force to moving any other thing (including ourself). Flashback again, that when we do a force, that mean"there is mass that has been moving with a certain acceleration". So, if we have do the work, we have do the force too. If we do the force, the acceleration is exist.
(C) : The forces acting upon the object are balancedYes, this statement is false. But, there may be confusion between "balanced" and "constant". If we say balance its meaning, "The object has not passing its equilibrium point or the forces acting (between left and right) are the same".
If the object has not passing its equilibrium point, the object not moving. If the object not moving, the number of works is zero.If the force acting is balance, so the resultant number is zero. When resultant ia zero, there is no force and also there is no works.(D) : The forces acting upon the object are unbalancedThisstatementistrue. From the explanation on point C, we can conclude if the imbalance of the force that occurs will cause the object to move or the occurrence of a force that causes a resultant in a certain direction. The existence of a shiftig or force causes the value of the work done by the object.

9. I had five books on my table two days ago but now ... only two on it A. there is B. there was C. there are D. there were karena ini pernyataannya present seharusnya antara opsi A dan C kan? dan karena objectnya ada dua berarti C. There Are kan? tapi saya masih ragu apa bener itu jawabannya, tolong beri penjelasan
Jawaban:
Betul sekali. Untuk countable noun yang jamak (seperti book => books) maka kita pakai There are....
Books nya tidak diulang lagi (there are two) adalah hal biasa dalam bahasa Inggris, karena merujuk kepada book yang sudah disebutkan sebelumnya.
Contoh lain:
I have three books, while my brother has two
Contoh lain penggunaa there is/there are
There is a man standing in the corner.
There are people in the stadium (people adalah jamak)
There is milk in the refrigerator. (milk adalah uncountable noun, jadi menggunakan is)
There are three hats under my bed.

16. What two conditions must be met if an object is to be in equilibrium?
Jawaban:
Syarat keseimbangan yang berlaku pada benda tegar adalah syarat keseimbangan translasi dan rotasi. Adapun syarat yang harus dipenuhi yaitu resultan dari semua gaya yang bekerja pada benda tegar harus sama dengan nol (∑F = 0) , dan resultan torsi yang bekerja pada benda tegar harus sama dengan nol (∑T = 0)

folow ya

20. Sorry if I posted this in the wrong subject but here's the question In the forces in pair are equal in strength, the object which they act does not move
Jawaban:
Penjelasan:
if the force is working in the opposite direction, obviously the object will not move tends to stay still, because the resultant force will be equal to zero but if the forces are moving in the same direction, the object can be said to be moving
