1. Which of the force diagrams in the figure correctly displays all of the horizontal forces exerted on the cart by the surrounding air?
Jawaban:
The force that propels a rocket is that the force provided by _______.
the expelled gas pushing on the rocket
When hitting a tennis ball with your racquet, the force on the ball has the same magnitude as the force on the _______.
racquet
A Volkswagen bug and a Volvo truck have a head-on collision. Which statement is true?
The magnitudes of both forces are the same.
A heavy crate is attached to the wall by a light rope, as shown in the figure. Another rope hangs off the opposite edge of the box. If you slowly increase the force on the free rope by pulling on it in a horizontal direction, which rope will break? Ignore friction and the mass of the ropes.
Both ropes are equally likely to break.
(Since the attached rope doesn't have to support any weight (as it did in the vertical case), the tension is the same in both ropes.)
Earth pulls on Moon. What is the reaction?
Moon pulls on Earth.
Which force is greater, the Earth's pull on the Moon, or the Moon's pull on the Earth?
Both pulls are the same
Since the Moon pulling on the Earth and the Earth pulling on the Moon are a reaction pair, the strengths of the two forces must be equal to each other.
If the cannon's recoil is the result of an equal and opposite reaction, why is the cannon's acceleration lower than the shell's acceleration?
The cannon has more mass than the shell.
(Since the cannon has more mass than the shell, it will have a lower acceleration because both objects experience the force. This can be understood from Newton's second law (a=F/m).)
Since movement of an object or system requires that a net force be applied to it, how can this occur if all action forces have opposite and equal reaction forces?
The action force doesn't act on the same object as the reaction force.
(Newton's second law can be applied to each of the objects. In fact, this explains why the two objects can have different resulting accelerations.)
n Lesson 3 of the tutorial, the horse is pulling a cart. What allows the horse to accelerate forward even though the cart is pulling back on the horse?
The force of friction the ground exerts on the horse is larger than the force the cart is pulling back on the horse.
(The net force exerted on the horse must be to the right if the horse accelerates to the right. The only two horizontal forces acting on the horse are friction (pushing forward) and the cart (pulling backward), so the friction force must be stronger.)
Which of the following is NOT a statement or consequence of Newton's third law?
There can never be only one force acting on an object
(Newton's third law doesn't specify how many forces can act on any one object (it just states that each of the forces will have a reaction force acting on other objects).)

2. In the figure, find ∠x .
Jawab:
85
Penjelasan dengan langkah-langkah:
Temukan sudut apa yang jika ditambah 275 akan menjadi 360
Anggap saja sudutnya y
275+y= 360
y= 360- 275
y= 85
Ada sudut lagi yang berpelurus terhadap x, anggap aja y.
Karena y dan z pada dua garis sejajar, maka
y+z= 180
85+z= 180
z= 180-85
z= 95
x+z= 180
x+95= 180
x= 180-95
x= 85
3. Explain the movement of oxygen molecules in figure 2
Jawaban:
itu adalah otak maaf kgo salah
4. Find the value of x in the figure below.
X + 12° + (180° - 43°) = 180°
x + 12° + 137° = 180°
x + 149° = 180°
x = 180° - 149°
X = 31°
Maaf klo ada yg salah
5. in the figure, 4 quadrants, each of radius 2 m, are removed from a rectangle. find the perimeter and the area of the figure
Jawaban:
Pertanyaan=
Kok yang nanya pakai Bahasa Inggris ya?
6. in the figure below,the value of x is.... cm
6 / 18 = x / x + 16
18x = 6x + 96
18x - 6x = 96
12x = 96
x = 96/12
x = 8
7. find the total area of the shaded region in the figure
Jawaban:
The total area of the shaded reagion in the figure = 76 cm
Penjelasan dengan langkah-langkah:
Total area of the shaded region:
[tex] = \frac{(5 + 7 + 6) \times 8}{2} + \frac{(7 + 6) \times 8}{2} - 2 \times \frac{8 \times 6}{2}[/tex]
[tex] = 72 + 52 - 48 = 76 \: {cm}^{2} [/tex]
8. Find the value of x in the figure below.
Jawaban:
2x + 5x + 3x + 90° = 360°
10x + 90° = 360°
10x = 360° - 90°
10x = 270°
x = 270°/10
x = 27°

16. Find the area of the shaded part in the figure below
4. Area = 49.2075 m²
5. Area = 63.25 m²
Penjelasan/Explanation
Number 4
The area of that figure equals to the area of the square minus the area of the semicircle.
The length of each side: s = 9 mRadius of semicircle: r = ½sA = s² – ½πr²
⇔ A = s² – ½π(½s)²
⇔ A = s² – ½(¼πs²)
⇔ A = s² – (1/8)πs²
⇔ A = s²[1 – (1/8)π]
⇔ A = 9²[1 – (1/8)×3.14]
⇔ A = 81(1 – 0.3925)
⇔ A = 81(0.6075)
⇔ A = 49.2075 m²
Number 5
The area of that figure equals to the sum of the area of the right-angled triangle and the area of the semicircle.
Base of triangle: b = 8 mHeight of triangle: h = 6 mRadius of semicircle: r = (½×10) m = 5 mA = ½bh + ½πr²
⇔ A = ½(bh + πr²)
⇔ A = ½(8×6 + 3.14×5²)
⇔ A = ½(48 + 3.14×25)
⇔ A = ½(48 + 78.5)
⇔ A = ½(126.5)
⇔ A = 63.25 m²
KESIMPULAN/CONLUSION4. Area = 49.2075 m²
5. Area = 63.25 m²
17. find the value of X in the figure below

20. find the value of b in the figure
b°+b°+90° = 180°
2b°+90°=180°
2b°=180°-90°
2b°= 90°
b° = 90°/2
b° = 45°
Value of b in the figure is 45°
