1. An object has weight 2 N on the surface of the earth. What is its weight if it is brought to the height of 1 500 km from the surface of the earth? [Radius of the earth = 6 370 km, g= 9.81 N kg-']


Jawaban:

w = 1,310700617 N

Penjelasan:

Karena soal ini berada di brainly.co.id, maka saya akan menjawab soal ini menggunakan bahasa indonesia

Cara mengerjakan soal ini adalah dengan cara memahami konsep gravitasi, maka

//Pertama Kita cari dulu massa dari objek

w = m . g

m = w / g

m = 2 / 9,81

m = 0,20387 Kg

//Kita cari Percepatan gravitasi pada h = 1500 Km = 1500000 m

g = G . M / R²

g = 6,67 e-11 . 5,97 e24 / (6370000 + 1500000)²

g = 6,4291 m/s

//Kita cari w pada h = 1500 Km

w = m . g

w = 0,20387 . 6,4291

w = 1,310700617 N

2. If the gravitational acceleration at Earth’s surface g and the radius of the earth R, the gravitational acceleration at a point has a distance R from the surface of the earth is…. 1/2 g g 2 g 1/4 g 4 g


Penjelasan:

`°Gravitasi Newton°`

g1/g2 = (r2/r1)²

g/g2 = ((R + R)/R)²

g/g2 = (2R/R)²

g/g2 = 2R²/R²

g/g2 = 2/1

g2=1/2g(A)

4. Please help me to solve this question The gravitational force of a satellite on the surface of the Earth of radius R is F. What is the gravitational force on the satellite when its height is R above the Earth?​


Jawaban:Jawaban:

F/4

Penjelasan:

h = distance from earth core to satellite

h = R+R = 2R

Fb = gravitational force on the satellite when its height is R above the Earth

F = G m / R^2

Fb = GM m / (2R)2

Fb = GM m / 4R2

Fb = (GM m / R2) / 4

Fb = F/4

5. find the surface area of a cylinder of radius 5cm and height 10cm​


Jawaban:

=150πcm

Penjelalasan:

Given

The Radius of a solid cylinder (r)=5cm

Height (h)=10cm

Hence

Total surface area =2πrh+2πr  

2

 

=2πr(h+r)

=2π×5(10+5)

=π×10×15

=150πcm

7. On a particular day, the height of the tide at East Coast Park was 0.8 m at dawnAt dusk the height of the tide increased by 40%. Find the height of the tide at duse​


Jawab:

Hi, Oppung will answer your question.

Here it is.

The height of the tide at East Coast Park = 0.8 m at dawn

increased by 40% means:

[tex]40\% \times 0.8 \\= \frac{40}{100} \times 0.8\\=0.4 \times 0.8\\=0.32[/tex]

Therefore, the height of the tide at East Coast Park = 0.8 m + 0.32 = 1.12 m

at dusk.


8. a warter reservoir at a height of 1.2 m is full of water. at the height of 90 cm from the water


90 cm = 0,09 m
12 m-0,09 m = 1,11 m

9. The gravitational force of a satellite on the surface of the Earth of radius R is F. What is the gravitational force on the satellite when its height is R above the Earth?​


Jawaban:

F/4

Penjelasan:

h = distance from earth core to satellite

h = R+R = 2R

Fb = gravitational force on the satellite when its height is R above the Earth

F = G m / R^2

Fb = GM m / (2R)2

Fb = GM m / 4R2

Fb = (GM m / R2) / 4

Fb = F/4

17. Determine the gravitational force attractional between the earth ( m=5,98 X 10^24 kg) and a 66,7 kg satelite is flying on the earth surface at distance of 6.67 X 10^6 m from earth center


GRAVITATION

F = ___?
M = 5.98×10^24 kg
m = 66.7 kg
r = 6.67×10^6 m

F = G M m / r²
F = 6.67×10^−11× 5.98×10^24 × 66.7)/(6.67×10^6)^2
F = 598 N ✔️Dicari Fgravitasi

Fgravitasi = G.mbumi.msatelit/r²
G = 6,67x10^-11
Mbumi = 5,98x10^24
Msatelit = 66,7 kg
Maka
Fgravitasi = 6,67x10^-11 . 5,98x 10^24 . 66,7/ 6,67 x 10^6 . 6,67 x 10 ^6

Tinggal dicoret yah, jadinya
F gravitasi = 5,98x10^24. 10. 10^-23
F gravitasi = 598N

20. A satellite moves in a circular orbit around Earth at a speed of 5000 m/s. Determine (a) the satellite’s altitude above the surface of Earth and (b) the period of the satellite’s orbit.


v = 5000 m/s
G = 6,67×10^-11
M = 5,98×10^24 kg
r = 6378×10^3 m

a. Circular orbit velocity follows the equation below :
v = square root GM/r+h
Where,
v ; circular orbit velocity
G ; universal gravitational constant
M ; Earth's mass
r ; Earth's radius
h ; height
h = GM/v^2-r
h = 9586399 m = 9586 km

b. Period of the satellite
T = square root 4pi^2(r+h)^3/GM
T = 5,57 hours
