If 2.2 lbs = 1.0 kg, and Megan Progress weighs 130 lbs, what is her weight in newtons?
1. If 2.2 lbs = 1.0 kg, and Megan Progress weighs 130 lbs, what is her weight in newtons?
Jawaban:
as it is given that
2.2 lbs = 1 kg
here we know that Megan Progress weighs 130 lbs
so its mass in kg is given as
m=130 1/2.2=59.1 kgnow to find the weight in Newton unit we can say
W=mg
W=59.1 * 9.8
W=579N
so 130 lbs weighs as 579 N in SI units

5. The ratio of Li Na’s mass to her father’s mass is 2 : 5. Li Na weighs 30 kg. Find her father’s mass. pls bantu akuuuuu
Jawaban:
her father’s mass is 75kg
Penjelasan dengan langkah-langkah:
lina : father
2 : 5

30 : 2 = n : 5
15 = n : 5
n = 15 x 5
n = 75
6. herry weighs 40kg hendra weighs 45kg hendy weighs 5kg lighter than herry what is the total weighs of them? they weighs kg
Jawaban:
In total, they weigh 120kg.
Penjelasan:
Herry = 40kg
Hendra = 45kg
Hendy = 40kg - 5kg (35kg)
40kg + 45kg + 35kg = 120kg
Semoga membantu :)
Jawaban:
120 Kg
Penjelasan:
to be known:
Herry weighs = 40KgHendra Weighs = 45KgHendy weight 5Kg lighter than Herry (Hendy lebih ringan 5Kg daripada Herry) = 40Kg - 5Kg = 35 KgHerry weighs + Hendra Weighs + Hendy Weighs
= 40Kg + 45Kg + 35Kg
= 120Kg
So, their total weight is 120Kg.

13. PLS BANGET AKU BUTUH CEPETWhich object has the greatest weight?A. A an object of mass 10 kg in a 15 N / kg gravitational fieldB. B an object of mass 15 kg in a 13 N / kg gravitational fieldC. C an object of mass 20 kg in a 9.0 N / kg gravitational fieldD. D an object of mass 50 kg in a 3.0 N / kg gravitational field
Jawaban:
Jawabannya adalah B
Penjelasan:
Soal tersebut mencari Weight (Berat). Adapun rumusnya adalah W= M×G
Jadi,yang paling berat adalah B karena
W = M×G
W = 15×13
W = 195 Newton.

15. The pressure due to the atmosphere is 100,000N/m2. If 10 newtons are equivalent to 1kg how much mass is pressing down on every square centimeter of our body?
Penjelasan:
Diketahui :
P = 100.000 N/m²10 N = 1 kgDitanya :
Tekanan dalam bentuk = kg/cm²
Jawab :
100.000 N/m² = ......... ( kg/cm²)
= (100.000 : 10)/(1 x 10.000)
= 10.000/10.000
= 1 kg/cm²

Jawab:
[3] 34 kg
Penjelasan dengan langkah-langkah:
Given that (the)
Number of students (n) = 3
ma = 33 kg, mb = 29 kg, mc = 40 kg
Find the average weight (Avg.)
Avg. = (ma+mb+mc)/n
Avg. = (33+29+40)/3
Avg. = 102/3
Avg. = 34 kg
So the average weight among the
three students is 34 kilograms (option 3)
