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?​

1. 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

3. a kitten and a basket has a mass of 3 kg . A hamster and a similar basket has a mass of 1.4kg . the mass of the kitten is 5 times the mass of the hamster .a. what is the mass of the hamster ? , b. what is the mass of the kitten ?

kitten = x ,hamster = y and baskest = z

x+z = 3 kg
y+z = 1,4 kg

z = x- y = 3 kg - 1,4 kg = 1,6 kg

x+y = 4,4 kg - 1,6 kg = 2, 8 kg

x = 5y 
5y +y = 2,8 kg
    6y  = 2,8 kg
      y = 2,8 kg /6
      y = 0,47 kg
x = 5y
   = 5 * 0,47 kg
   = 2,35 kg 

a. mass off  hamster = 0,47 kg
b. mas off kitten = 2,35 kg

bonus...mass of basket = 1,6 kg

5. The mass of a bag of rice is 3 times the mass of a bag of fruits. If the mass of the bag of the rice is 15 kg, find the mass of the bag of fruits. (please put the calculation)

Jawaban:

5kg

Penjelasan dengan langkah-langkah:

Mass of bag of rice : 3 = Mass of bag of fruit

15 : 3 = 5

Jawaban:

5 kilograms

Penjelasan dengan langkah-langkah:

15 divided by 3 equal to 5

because the weight of the bag of rice is 3 times the weight of the bag of fruit, so the weight of the bag of fruit is the weight of the bag of rice divided by three

6. 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

8. 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

9. calculate the molar mass of a compound if 0.372 mol of it has a mass of 152g​

Jawaban:

Massa molar suatu senyawa yang memiliki 0,372 mol dan massa 152g adalah 408.6g/mol

MENGHITUNG MASSA MOLAR :

Massa molar suatu zat dapat dihitung dengan membagi massa zat dengan jumlah molnya . Itu adalah;

Massa molar (g/mol) = massa (g) no. mol ( mol)

Berdasarkan pertanyaan ini, suatu senyawa memiliki 0,372 mol dan massa 152g, maka massa molar senyawa tersebut adalah sebagai berikut:

Massa molar = 152g 0,372mol

Massa molar = 408.6g/mol

Jadi, massa molar suatu senyawa yang memiliki 0,372 mol dan massa 152g adalah 408,6 g/mol.

13. the mass of a watermelon is 7/1 kg. the mass of a apples is 2/5 kg less than the mass of the watermelona. what is the mass of the applesb.what is the total mass of the apples and watermelon​

Diketahui:

Berat semangka = 7/1 kg

Berat apel = 2/5 kg kurang dari semangka

Maka:

a. Berat apel = 7/1 - 2/5

                     = 35/5 - 2/5

                     = 33/5 = 6 3/5

b. Berat apel dan semangka = 7/1 + 6 3/5

                                                = 35/5 + 33/5

                                                = 68/5 = 13 3/5

18. Ron divided 207 kg of rice into 3 bags, A, B and C, the ratio of the mass of rice in Bag A to the mass of rice in Bag B was 1 : 2. The ratio of the mass of rice in Bag B to the mass of rice in Bag C was 4 : 3. a. Find the ratio of the mass of rice in Bag A to the mass of rice in Bag B to the mass of rice in Bag C. b. Find the mass of rice in Bag A dengan cara ya!!

Jawaban:

a. 2:4:3

b. 46 kg

Penjelasan:

a. A : B = 1 : 2

B : C = 4 : 3

multiply either equation so that both equations have the same value for B. i choose to multiply the first equation by 2. so,

A : B = 2 : 4

since both ratios have the same value for B, we can merge them together.

A : B : C = 2 : 4 : 3

b. mass A = A/total mass x total mass

since we have the ratio for A and the total mass = 2:(2+4+3),

mass A = 2/9 x 207

= 2 x 23

= 46 kg
