which are the correct sentences of particle an
1. which are the correct sentences of particle an
Jawaban:
Use an for a single thing that starts with vocal alphabeth such as a, i, u, e, o.
There is no choice though :/
2. A particle travels 28.5 km in 30 minutes. Find the speed of the particle in km/h
Jawab:
57 km/h
Penjelasan dengan langkah-langkah:
from the question, we know that:
D = 28,5 km
T = 30 minutes = 0,5 hour
Because the formula is Speed = [tex]\frac{distance}{time}[/tex]
so, Speed = [tex]\frac{28,5}{0,5}[/tex] = 57 km/h
Hope you find it helpful! Feel free to ask if there's something you don't understand from my explanation :)
3. Gas arrangement of particle
Jawaban:
Answer :
The particals which are atoms in gases are freely packed with no regular arrangements.
Additional information :
The atoms in gases are very free
to move from place to place. It also have very less intermolecular forces. The atoms in gases have more space between them when compared to liquids and solids.
hope this will help u !!!

6. An empty box has a mass of 46 grams. Jims packs 20 cans of soup into the box. Each can of soup has a mass of 450 grams. What is the total mass of the box of soup?
Jawab:
946 g
Penjelasan dengan langkah-langkah:
Diketahui :
[tex]m^{box}[/tex] : 46 g
can/box : 20
[tex]m^{can}[/tex] : 450
Ditanya :
[tex]m^{box of soup}[/tex] : ?
Jawab :
[tex]m^{box of soup}[/tex] = [tex]m^{box}[/tex] + n([tex]m^{can}[/tex])
= 46 g + 20(450 g)
= 46 g + 900 g
= 946 g
Jadi :
total mass of the box of soup is : 946 grams/0,946 kg
Sorry if im wrong :)

8. Which particle is an ion?
Jawaban:
Yang menunjukkan ion adalah opsi D
Penjelasan:
Jumlah proton dan elektron dalam unsur netral adalah sama. Jika jumlah proton dan elektronnya berbeda maka unsur tersebut adalah ion, bisa ion positif atau ion negatif.
Ion positif = kekurangan elektron
Ion negatif = kebanyakan elektron
9. An object has mass of 6kg and 6 m from ground. Calculate the potential energy!
Jawaban:
mass (m) = 6 kg
height (h) = 6 m
gravitational acceleration (g) = 10 m/s²
Potential Energy (Ep) = m×g×h
Ep = 6 kg × 6 m/s² × 10 m
Ep = 360 kg m²/s² = 360 Joule.

Jawaban:
49,2km/h
Penjelasan dengan langkah-langkah:
s = 24,6km
t = 30minutes or 0,5hours
v=s/t
v=24,6/0,5
v=49,2km/h

PROBLEMS Force F acting on a particle of mass m has the following dependencies: (a) F(x, t) = f(x)g(t) (b) F(x,t)=f(x)g(t) (c) F{x,x)=f(x)g{x) Write the differential equations describing these situations. Which of these differential equations can be solved to describe the motion of the particle? Explain.

12. An elevator with a mass of 2000 kg rises with an acceleration of 1.0 m/s/s. What is the tension in the supporting cable?
Jawaban:
T - W = ma
W = mg
T = m(g + a)
Asumsikan g = 10 m/s^2
T = 2000(10 + 1)
T = 22000N
Penjelasan:
maaf kalo salah
Jawaban:
22000 newton
Penjelasan:
m = 2000kg
a = 1 m/s²
g = 10 m/s²
berat elevator terhadap bumi = m x g = 20000 Newton
tegangan yang ditimbulkan harus melebihi berat elevator terhadap bumi
dengan kata lain percepatan yang dihasilkan harus lebih besar dari percepatan gravitasi
sehingga percepatan sebenarnya tanpa pengaruh gravitasi = g + a = 10 + 1 = 11 m/s²
Tegangan yang dihasilkan = m x 11 = 2000 x 11 = 22000 newton
13. In fig 21-25 particle 10f charge + 1.0 Nc and particle 2 of charge -3.0 Nc are held at sparation L=10.0 cm on an X axis. If particle 3of uknown charge 93 is to be located such that the net elescrotastic force on'in from particle 1 and 2 is zero,what must be the (a) x and (b) y cordinates of particle 3?
Diketahui:
q1 = 1 nC
q2 = -3 nC
L = 10 cm
Ditanya:
a. Koordinat x
b. Koordinat y
untuk q3 dimana F=0
Jawab:
q3 tidak mungkin diantara q1 dan q2 karena gaya dari q1 dan q2 searah.
q3 tidak mungkin di kanan q2 krn gaya dr q2>gaya dari q1.
Jadi q3 ada dikiri q1.
F₁₃ = F₂₃
kq1.q3/d² = kq2.q3/(L+d)²
(L+d)²/d² = q2/q1
[(L+d)/d]² = 3/1
(L+d)/d = √3
L+d = d√3
L= d(√3-1)
d = L/(√3-1)
d = 10/0,7 = 13,6 cm
a. q3 harus ditempatkan pada x = -13,6 cm sepanjang sb x.
b. karena q3 harus pada sb x maka y=0
14. The mass of an Encyclopaedia is 1.05 kg. The mass of the encyclopaediais thrice the mass of a storybook.The mass of a dictionary book is 0.72 kgmore than the storybook. What is the mass of the dictionary bookuse working
Jawaban:
Massa sebuah Ensiklopedia adalah 1,05 kg. Massa ensiklopedia adalah tiga kali massa buku cerita. Massa buku kamus adalah 0,72 kg lebih dari buku cerita. Berapa massa buku kamus?
Massa ensiklopedia = 1.05 kg
Massa buku cerita = ⅓ massa buku ensiklopedia
cara — ⅓ x 1,05 = 0,35 kg
Massa kamus = massa buku cerita + 0,72 kg
cara — 0,35 + 0,72 = 1,07 kg
semoga membantu

15. what force is needed to give a mass of 20kg an acceleration of 5.0 m/s
Jawaban:
100 N
Penjelasan:
Rumusnya a=f/m
Caranya substitusi dulu hal yang diketahui yaitu massa dan akselerasi
5=f/20
langsung kali silang saja
F=20 X 5
=100 N

16. the ratio of amy's mass to bala's mass is 4 : 3. the ratio of bala's mass to chandra's mass is 9 : 7. what is the ratio of amy's mass to bala's mass to chandra:s mass?
A : B
4 : 3
B : C
9 : 7
A : B : C
= (4x9) : (3x9) : (7x3)
= 36 : 27 : 21
= 12 : 9 : 7
Jadi perbandingannya adalah 12 : 9 : 7
17. an empty box has a mass of 75 g. David packs 12 jars of jam, each mass 380 g into the box. What is the total mass of 9 such boxes of jam ?
Jawaban:
1 box = 12 jars of jam
the mass of 1 box of jam = 75g + (12 × 380g)
= 75g + 4.560g
= 4.635g
total mass = 9 × 4.635g
= 41.715g
Jawab:
the process:
380 x 9 = 3. 420
3. 420 + 75 = 3. 495
sorry klo salah :))

20. The mass of a dictionary is 1.28 kg. The mass of the dictionary is twice the mass of a storybook. The mass of an encyclopaedia is 1.4 kg more than storybook. What is the mass of the encyclopaedia?
Jawaban:
2.04 kg
Penjelasan dengan langkah-langkah:
Jika berat sebuah kamus 2 kali berat buku cerita, maka berat buku cerita adalah setengah dari berat kamus. Sehingga berat ensiklopedia adalah
1.4 kg + (1.28 ÷ 2) kg
= 1.4 kg + 0.64kg
= 2.04 kg
